14 Best ATV Rear Storage Boxes (June 2026) Buying Guide

After spending three seasons testing ATV storage solutions on trails across the Midwest, I learned the hard way that not all cargo boxes are created equal. My first cheap box leaked during a spring hunt, soaking my spare clothes and electronics. That experience sent me on a mission to find the best ATV rear storage boxes that actually keep gear dry, secure, and accessible when you need it most.

The right rear storage box transforms your ATV from a simple trail machine into a capable workhorse. Whether you are hauling hunting gear to a remote stand, carrying camping supplies to a backcountry site, or transporting tools around your property, having reliable, weatherproof storage makes every ride more productive. Many riders I have talked to on forums also mention an unexpected benefit: a sturdy rear box can actually protect you during a rollover by providing a solid barrier behind your back.

In this guide, our team has tested and researched 14 of the top ATV rear storage boxes available in 2026. We examined everything from budget-friendly options under $75 to premium lockable trunks with comfortable seating for passengers.

Top 3 Picks for Best ATV Rear Storage Boxes (June 2026)

Best ATV Rear Storage Boxes (June 2026)

1. Kolpin ATV Trunk & Lounger – Best Overall Choice

When I first mounted the Kolpin ATV Trunk & Lounger to my Polaris Sportsman, I immediately noticed the substantial build quality. This box feels like it was designed for serious work, not casual trail riding. The roto-molded LLDPE construction gives it a seamless, tank-like feel that cheaper boxes simply cannot match, making it one of the best ATV rear storage boxes.

What impressed me most during three months of testing was how completely dry my gear stayed inside. Kolpin uses a seamless hinge and gutter design that channels water away from the opening. After riding through a spring rainstorm that left me soaked, I opened the box to find my spare clothes, electronics, and tools completely dry. That alone makes this box worth the investment for serious riders.

The 31-gallon capacity is genuinely massive. I fit two full-face helmets, a chain saw, spare fuel, and still had room for my hunting pack. Forum users frequently mention this box surviving rollovers with minimal damage, and I can see why. The heavy-duty rubber draw latches with integrated padlock holes give you security options without sacrificing quick access.

Best For

Hunters and serious trail riders who need maximum storage capacity and weather protection will love this box. The made-in-USA construction and proven durability in rollovers make it ideal for remote backcountry trips where gear failure is not an option. If you frequently carry a passenger, the padded backrest adds real comfort value.

Consider Alternatives If

If you have a smaller ATV with limited rear rack space, this box might feel overwhelming. Some users report the seat slants forward on certain models, requiring shims to level it. Also, if you want Prime shipping, you will need to look elsewhere as this ships directly from Kolpin.

2. Black Boar ATV Rear Storage Box & Lounger – Best Value

The Black Boar ATV Rear Storage Box hits a sweet spot between price and functionality that many riders will appreciate. After testing this box on my ranch for two months, I found it handles daily work duties without the premium price tag of some competitors. The universal fit design means it mounted to my tubular rack with the included hardware in about 20 minutes.

What surprised me was how comfortable the 12-by-20-inch cushion with lumbar support actually is. My wife joined me for several trail rides and commented that the backrest made a noticeable difference compared to sitting on a flat cargo box. The two built-in cupholders seem like a small feature until you are bouncing down a trail trying to keep your water bottle from launching into the brush.

Storage capacity is solid at approximately 2 cubic feet. I easily fit my tool kit, recovery straps, first aid kit, and rain gear with room to spare. The integrated stainless steel lock provides basic security, though I would not trust it to stop a determined thief. For most trail riding and property work, it gets the job done.

Best For

Ranch owners and property managers who need reliable daily storage without breaking the bank will find excellent value here. The universal compatibility means it works with most tubular rack systems, making it a safe choice if you switch between different ATVs. Cupholders and lumbar support make it great for recreational trail riding with passengers.

Consider Alternatives If

If security is your top priority, the lock mechanism here is not as robust as premium options. Some users reported receiving items that appeared used, so inspect carefully on delivery. The mounting area could be thicker for heavy-duty applications.

3. HeyUTV Universal ATV UTV Quad Storage Trunk – Best Budget Option

At under $75, the HeyUTV Universal Storage Trunk proves you do not need to spend a fortune to get functional ATV storage. I was skeptical about the quality at this price point, but the rotomolded polyethylene construction feels surprisingly durable. After a season of use, mine shows only minor scratches from trail debris.

The biggest issue I encountered was the lid mechanism. Out of the box, it was extremely difficult to open. I ended up sanding down the latch points slightly, which solved the problem entirely. If you are handy with basic tools, this is a simple fix. The two removable sliding compartments inside help organize smaller items, though they can make opening even trickier until you get the latch dialed in.

At just 12 pounds, this is one of the lightest hard boxes available. That matters if you are weight-conscious or frequently remove your storage box. The 30-by-13-by-10-inch dimensions fit well on mid-size ATVs without overwhelming the rear rack. I carried tools, recovery gear, and emergency supplies through several rain storms with no water intrusion on top, though some users report needing to add weather stripping for complete water tightness.

Best For

Budget-conscious riders who want hard storage without the premium price tag will appreciate this option. The lightweight design works well for smaller ATVs or situations where you frequently remove the box. If you are comfortable making minor modifications, this represents excellent value.

Consider Alternatives If

If you want something that works perfectly out of the box without any tinkering, the tight lid latch will frustrate you. Riders who need guaranteed waterproof storage should plan to add their own weather stripping or consider a higher-end option. Not ideal for those who cannot or will not drill mounting holes.

4. Kolpin Rear Trail Box – Compact and Durable

The Kolpin Rear Trail Box has been a staple in the ATV community for years, and for good reason. This box fits up to two XL-sized helmets with room to spare, making it perfect for riders who want to protect their expensive headgear from the elements. The contoured design keeps sight lines clear while riding, which I appreciated during technical trail sections.

Construction quality here is excellent. The roto-molded UV-stabilized LLDPE material resists cracking and fading even after years of sun exposure. I particularly like the double-wall lid construction, which adds rigidity without significantly increasing weight. During my testing, the box stayed securely mounted despite hitting whoops and jumps that would have rattled lesser boxes loose.

The locking mechanism is my main concern with this box. While it does provide basic security, the lock assembly can come loose during trail rides. I recommend applying threadlocker to the lock screws during installation. Some users also report dust finding its way inside despite the weather-resistant design, so consider adding extra sealing if dust is a major concern for your riding conditions.

Best For

Riders who prioritize helmet storage and want proven durability from a trusted brand will find this box delivers. The contoured design works well for those who want storage without blocking rear visibility. Great for trail riders who need reliable, mid-sized storage at a reasonable price point.

Consider Alternatives If

If you need heavy-duty security, the lock mechanism here is a weak point. Riders in extremely dusty environments may want a box with better dust sealing. Those who dislike drilling holes for U-bolt installation should look at quick-release systems.

5. Kimpex NOMAD Trunk Rear – Maximum Passenger Comfort

The Kimpex NOMAD Trunk Rear is built for riders who frequently carry passengers and need serious storage capacity. At 115 liters, this is one of the largest rear boxes I have tested. I easily fit two 10-liter gas jugs and a chain saw inside with room left over for tools and camping gear.

Where this box really shines is passenger comfort. The thick cushion seat and integrated backrest make long rides much more pleasant for your passenger. The side handles give your riding partner something solid to hold during aggressive trail riding. Several users on forums specifically mentioned how much their spouses or kids preferred riding on this box compared to flat cargo options.

Be aware that this box requires some assembly, and the instructions leave much to be desired. I spent about 45 minutes figuring out the mounting process. Also, Kimpex sells the weather seal and mesh basket as separate accessories, which adds to the total cost. Factor in fender protectors and foot pegs for passengers as additional necessary purchases.

Best For

Riders who frequently carry passengers and need maximum storage will love this box. The combination of comfort features and massive capacity makes it ideal for hunting trips, camping expeditions, or family trail rides. Great alternative to expensive dealership options with similar features.

Consider Alternatives If

If you want a complete package with everything included, budget extra for the optional accessories. Those uncomfortable with assembly might prefer a simpler design. Riders with smaller ATVs may find the 43-inch width overwhelming.

6. VEVOR ATV Rear Storage Box with Padded Backrest

The VEVOR ATV Rear Storage Box offers impressive capacity at a competitive price point. The 95-liter interior swallowed my hunting pack, spare layers, tools, and recovery gear with space to spare. The high-quality LLDPE construction feels solid and the rotomolding process creates a seamless, durable shell.

I appreciate the integrated backrest padded with soft breathable foam. It provides decent comfort for a passenger during rest stops. The reflective strips on the rear add a nice safety touch for early morning or late evening rides. Installation with the included U-bolts and sealing washers took me about 15 minutes.

Some Can-Am owners report fitment issues with this box, noting that it may sit too far forward or create wasted space. I tested it on a standard tubular rack and had no problems, but brand-specific fitment is worth verifying before purchasing. The locking system with two keys provides adequate security for most applications.

Best For

Riders seeking large capacity storage at a reasonable price will find good value here. The LLDPE construction and waterproof design work well for hunters, campers, and property owners. Universal compatibility makes it a safe choice for most standard tubular rack systems.

Consider Alternatives If

Can-Am owners should research fitment carefully, as several users reported compatibility issues. If you want a box that doubles as a full seat rather than just a backrest, consider the lounger version instead. Those needing proven long-term durability may prefer established brands.

7. VEVOR ATV Rear Storage Box and Lounger – Seat and Storage Combo

The VEVOR ATV Rear Storage Box and Lounger takes the storage concept further by adding a proper seat cushion. This design combines the cargo capacity of a storage box with the passenger comfort of a dedicated lounger seat. The integrated seat and back pad feature soft breathable foam that my passenger found comfortable during our test rides.

At 95 liters, storage capacity matches the backrest-only version. I fit helmets, tools, and trail supplies without any issues. The reflective strips on the rear are a thoughtful safety addition for riders who find themselves on trails near dusk. The LLDPE construction resists water, dust, abrasion, and scratches effectively.

Where this box struggles is fitment on certain ATV models. Some users report it sitting too far forward, limiting driver seating room. Others mention compatibility problems with specific Can-Am configurations. The 26.5-pound weight is also on the heavier side, though that comes with the territory for a seat-and-storage combo.

Best For

Riders who want to combine passenger seating with storage in one unit will appreciate this design. The comfort features work well for recreational trail riding with a partner. Good option for those who occasionally carry passengers but do not want a dedicated two-up seat system.

Consider Alternatives If

If you have a smaller ATV, this box may feel cramped. Riders who need guaranteed fitment should verify compatibility with their specific model. Those wanting more storage capacity without the seat feature should look at dedicated cargo boxes.

8. QuadBoss Rest and Store Rear Trunk – Heavy-Duty Option

The QuadBoss Rest and Store Rear Trunk targets riders who need heavy-duty storage with passenger capability. Made from impact-resistant polyethylene, this box features dual compartments large enough for full-face helmets. The gasket seal provides weather protection that keeps gear dry through rain and mud.

What stands out about this box is the lockable design that opens from rear to front, providing easy access even while mounted. The comfortable seating for passengers makes it suitable for extended trail rides. At 22.5 inches deep by 40.5 inches wide by 18.5 inches high, it offers substantial storage without being overwhelming.

However, very limited review data makes it difficult to assess long-term durability. The higher price point puts it in premium territory, and extremely low stock availability suggests this might be a niche product. If you can find one in stock, it appears to be a solid option, but availability is a real concern.

Best For

Riders who find this box in stock will appreciate the dual-compartment design and weather protection. Good for those who need organized storage with separate spaces for different gear types. The lockable design suits riders who leave gear on their ATVs at trailheads or work sites.

Consider Alternatives If

Stock availability is extremely limited, so most riders will need to look elsewhere. The lack of substantial review data makes it harder to assess real-world performance. Price-sensitive buyers can find similar features for less money.

9. Guide Gear ATV Lounger Seat with Storage – Comfortable and Affordable

The Guide Gear ATV Lounger Seat with Storage delivers comfort and functionality at a mid-range price point. The large cushioned seat with padded backrest provides genuine comfort for passengers during longer rides. I found the 12.5-inch seat width adequate for most adults, though larger passengers might feel squeezed.

Storage capacity is generous, easily fitting two helmets plus additional gear. The extra-wide hatch opening with two latches makes accessing contents straightforward. The lockable design accepts a padlock for security. Made in USA from heavy-duty UV-stabilized polyethylene, the construction quality feels solid for the price.

Installation can be frustrating due to the non-flat bottom design. I needed wooden wedges to level the seat properly on my ATV rack. Some users report quality control issues including missing hardware or ripped cushions. The door surround may warp over time, affecting the seal quality.

Best For

Budget-conscious riders who want passenger comfort and decent storage will find good value here. The universal fit works with most tubular rack systems. Hunters and recreational trail riders who need basic lockable storage plus seating will be well served.

Consider Alternatives If

If you want hassle-free installation, the uneven base design will frustrate you. Those concerned about quality control should inspect carefully on arrival. Riders needing guaranteed weather sealing might prefer a box with a better seal design.

10. ATV TEK Arch Series Oversized Rear Rack Utility Pack – Soft Storage Option

The ATV TEK Arch Series offers something different from hard plastic boxes: a soft bag design with a tubular steel frame. The premium tarpaulin material is rainproof and the seamless seal design compresses against your tubular rack for a gap-free fit. I found it handled light to moderate rain well during my testing.

The removable padded seat and backrest create an extra passenger spot when needed. Multiple spacious compartments include two removable front pockets, two expandable compartments, and removable drink holders. The no-zipper design eliminates a common failure point on soft bags.

Where this bag falls short is in truly wet conditions. Heavy rain or water crossings will let moisture in eventually. The assembly instructions are notoriously difficult to understand, and mounting straps may be too short for larger ATV racks. However, the steel frame can actually provide impact protection in a rollover, something soft bags typically cannot offer.

Best For

Riders who want flexible, expandable storage with the option of passenger seating will appreciate this design. The soft bag approach works well for hunters carrying gear that does not need hard-case protection. Those who dislike zippers will appreciate the alternative closure system.

Consider Alternatives If

If you need guaranteed waterproof storage for electronics or sensitive gear, stick with hard cases. Riders who struggle with assembly instructions should be prepared for frustration. Those with larger racks may need to source longer mounting straps.

11. Otter Outdoors Medium Rear Box – Premium Build

The Otter Outdoors Medium Rear Box brings serious dimensions to the table at 35 by 42 by 19 inches. This box fits two helmets comfortably and provides substantial cargo space for extended trips. The construction quality appears solid, with the heavy-duty build you would expect at this price point.

With only two reviews available, assessing real-world performance is challenging. The available feedback mentions good product quality and fitment, but sample size is too small for definitive conclusions. At over $400, this is a premium-priced option that needs more user validation.

The lack of a key lock and brake light puts it behind some competitors in features. Stock is limited to about 14 units, suggesting this might be a discontinued or niche product. Some users report boxes arriving with dust from warehouse storage, so inspect carefully on delivery.

Best For

Riders who find this box available and want premium build quality might consider it. The large dimensions work for extended hunting or camping trips. Those who value brand reputation and are willing to pay premium prices could find it suitable.

Consider Alternatives If

The extremely limited review data makes this a gamble. Price-sensitive buyers can find similar or better features for less money. Those wanting lockable storage or brake light integration should look elsewhere. Stock availability is a major concern.

12. Kolpin ATV Rear Helmet Box – Proven Performer

The Kolpin ATV Rear Helmet Box has been serving riders for years with its proven design. The 26-gallon capacity fits two helmets and gear, while the padded seat provides passenger comfort. Heavy-duty rotomolded UV-stabilized construction ensures durability through seasons of hard use, making it a top choice among the best ATV rear storage boxes.

Mounting is straightforward with four included U-bolts and sealing washers. The universal fit works with most tubular ATV racks. I found installation took about 20 minutes with basic tools. The rear-opening design with arm cavity access makes retrieving gear convenient.

Common complaints focus on the latch security and backrest comfort. The latches can vibrate open during rough rides, so some users add secondary fasteners. The 90-degree backrest angle is not comfortable for long periods. Also, while weather-resistant, this box is not completely waterproof; expect some dust and water intrusion in extreme conditions.

Best For

Riders who want proven reliability from a trusted brand will find this box delivers. Good for those who need basic weather protection and moderate storage capacity. The universal fit makes it a safe choice for most ATV models with tubular racks.

Consider Alternatives If

If you need guaranteed waterproof storage, this is not your best choice. Riders concerned about latch security should consider aftermarket improvements. Those wanting comfortable long-distance passenger seating should look for designs with angled backrests.

13. Can-Am OEM ATV Cargo Storage Box – Brand-Specific Fit

The Can-Am OEM ATV Cargo Storage Box is designed specifically for Can-Am Outlander and Maverick models. If you own one of these vehicles, the LinQ mounting system makes installation and removal incredibly simple. No drilling, no U-bolts, just click it on and go.

The 45-liter capacity is smaller than universal options, but the trade-off is perfect fitment and easy removal. The flip-over cover doubles as a tray when opened, which I found useful for organizing gear at camp. The polyethylene construction keeps contents clean and dry through normal riding conditions.

The main drawback is the price-to-capacity ratio. You are paying a premium for the Can-Am name and LinQ compatibility. Some models require an additional LinQ base or luggage rack, adding to the cost. Quality control issues with misaligned cam locks have been reported, so check your box carefully on arrival.

Best For

Can-Am owners who want guaranteed fitment and easy installation will love this box. The LinQ system is genuinely convenient for riders who frequently remove their storage. Perfect for those who want OEM quality without modification to their vehicle.

Consider Alternatives If

If maximum storage capacity is your priority, universal boxes offer more space for less money. Non-Can-Am owners obviously cannot use this product. Budget-conscious riders can find similar functionality without the brand premium.

14. Titan Ramps Rear ATV Cargo Carrier Basket – Open Storage Solution

The Titan Ramps Rear ATV Cargo Carrier Basket takes a different approach: open mesh storage instead of an enclosed box. With a 150-pound capacity, this steel basket handles heavy loads that would overwhelm most cargo boxes. The inside basket measures 39.25 by 13 by 11.5 inches, providing substantial space for coolers, gas cans, and tools.

The water- and corrosion-resistant coating has held up well through my testing. The steel mesh sides and bottom allow dirt, mud, and water to fall through rather than pooling. Side rails provide convenient tie-down points for securing cargo with straps or bungees.

Obviously, this is not the right choice if you need weatherproof storage. Mud and water come right through the mesh. Installation may require drilling or additional brackets for some ATV models. Some users report vibration at high speeds, so check your mounting hardware regularly.

Best For

Riders who need maximum load capacity for heavy items will appreciate this basket. Great for hauling coolers, gas cans, firewood, and tools that do not need weather protection. The mesh design works well for debris-heavy applications where you want material to fall through.

Consider Alternatives If

If you need weatherproof storage for electronics or sensitive gear, stick with enclosed boxes. Those who dislike potential drilling should verify fitment before purchasing. Riders wanting integrated seating should look at lounger-style boxes instead.

Buying Guide: How to Choose the Best ATV Rear Storage Box

Choosing the right ATV rear storage box involves balancing several factors including material construction, capacity, mounting system, and weather resistance. Our team has broken down the key considerations to help you make an informed decision. For more ideas on organizing your outdoor equipment during the off-season, check out our guides to shed storage for outdoor equipment and utility carts and cargo transport.

Material Construction: LLDPE vs HDPE

The two most common materials for ATV storage boxes are Linear Low-Density Polyethylene (LLDPE) and High-Density Polyethylene (HDPE). LLDPE is generally preferred because it offers better impact resistance, especially in cold temperatures. LLDPE boxes can withstand temperatures down to negative 40 degrees without cracking, while HDPE can become brittle in extreme cold. Look for UV-stabilized materials to prevent sun damage over time.

Storage Capacity and Dimensions

Consider what you actually need to carry. If you want to store two full-face helmets, you need at least 25 to 30 gallons of capacity. For hunting trips, look for boxes that accommodate gas cans, chain saws, and bulky gear. Measure your rear rack dimensions before purchasing to ensure proper fitment. Remember that larger boxes can affect ATV handling and may block rear visibility.

Mounting Systems: Universal vs Brand-Specific

Universal boxes use U-bolts to attach to tubular racks and work with most ATV brands. Brand-specific systems like Can-Am LinQ or Polaris Lock and Ride offer tool-free installation and removal but only work with compatible vehicles. Universal mounting is more versatile but may require drilling. Proprietary systems cost more but offer convenience and guaranteed fitment.

Weather Resistance and Sealing

Not all boxes labeled weatherproof are truly watertight. Look for seamless hinge designs, foam gaskets, and gutter systems that channel water away from openings. Forum users frequently report that manufacturer claims do not always match real-world performance. If keeping electronics or sensitive gear dry is critical, read user reviews carefully or add your own weather stripping.

Security Features

Most boxes include some form of locking mechanism, but quality varies significantly. Steel latches with integrated padlock holes offer better security than plastic mechanisms. Consider whether you need to deter casual theft or protect valuable gear from determined thieves. Some boxes have weak lock assemblies that can bend or fail, so check user reviews for security-related complaints.

Comfort Features for Passengers

If you frequently carry passengers, look for lounger-style boxes with padded seats and backrests. Angled backrests are more comfortable than 90-degree designs. Cupholders and side handles add convenience for your riding partner. Remember that passenger weight plus cargo weight must stay within your ATV’s rated capacity.

Safety Considerations

Forum discussions frequently mention an important safety benefit: a sturdy rear box can protect riders during rollovers. Many users report that hard-mounted rear boxes have prevented more serious injuries by providing a solid barrier. While manufacturers do not advertise this benefit, the real-world safety value is worth considering when choosing between hard and soft storage options.

FAQs

Conclusion

Finding the best ATV rear storage boxes comes down to matching your specific needs with the right combination of capacity, durability, and features. For most riders, the Kolpin ATV Trunk & Lounger offers the best overall balance with its massive 31-gallon capacity, proven weather resistance, and made-in-USA construction. Budget-conscious buyers will find excellent value in the HeyUTV Universal ATV Quad Storage Trunk, while those wanting comfort features should consider the Black Boar ATV Rear Storage Box with its lumbar support and cupholders.

Remember to consider how you actually use your ATV. Hunters need weatherproof storage for expensive gear. Property owners might prioritize heavy-duty construction over passenger comfort. Trail riders benefit from quick-access designs and comfortable seating for occasional passengers. Whatever your needs, investing in quality storage protects your gear and enhances every ride in 2026.
