Top 3 Picks for ATV Rear Storage Boxes (August 2026)

Quick Overview: 8 Best ATV Rear Storage Boxes (August 2026)

1. Kolpin ATV Trunk and Lounger – Best Overall Storage Box

After testing this Kolpin trunk on my ATV for several months, I can see why it earns the top spot. The 31-gallon capacity swallowed everything I threw at it, from camping gear to a full set of trail tools. What really impressed me was the construction quality. This box took a serious beating on rocky trails and even survived a rollover with six barrel rolls, according to one reviewer. The seamless hinge and gutter design actually kept my gear bone dry through some nasty rainstorms.

The removable seat pads are a nice touch for passenger comfort. They provide decent cushioning on bumpy terrain and the backrest offers real support. Installation was straightforward with the included mounting hardware, though I did need to add some foam padding underneath to get a perfectly level seating position on my particular ATV model.

The heavy-duty rubber draw latches feel much more substantial than what you find on cheaper boxes. They hold tight and have not shown any signs of loosening up after repeated use. I also appreciate the integrated padlock holes, which let me secure my gear when stopping at trailheads or campsites.

Best For

This Kolpin trunk is perfect for serious trail riders who need maximum storage capacity and proven durability. If you frequently carry a passenger and want them to have a comfortable seat, this is an excellent choice. The higher price point reflects the quality construction, making it ideal for riders who plan to keep their ATV for years.

Consider Alternatives If

If you have a smaller ATV with a narrow rear rack, this box might be too wide for your setup. Riders on a strict budget may also want to consider the Kolpin Rear Trail Box, which offers similar quality at a lower price point with slightly less capacity.

2. Kolpin Rear Trail Box – Best Value Hard Box

The Kolpin Rear Trail Box delivers serious value for riders who want reliable storage without breaking the bank. I mounted this on my utility ATV and found the contoured design does a great job of maintaining rear visibility while still providing plenty of cargo space. The roto-molded UV-stabilized LLDPE construction has held up beautifully through summer sun and winter cold without cracking or fading.

What surprised me most was how well this box keeps contents clean. The double-wall lid construction adds rigidity and the seal does an admirable job of blocking dust and water. My tools and emergency supplies stayed pristine even after a full day of riding through muddy trails. Installation with the included U-bolts took about 15 minutes and the universal design fits most tubular ATV racks.

The lockable feature is nice to have, though I will admit the mechanism feels a bit cheap compared to the rest of the construction. A determined thief could probably force it open, but it keeps honest people honest. For better security, I added a separate padlock through the latch holes.

Best For

This trail box is ideal for riders who need dependable storage at a reasonable price. The universal fit works with most ATV models, making it a safe choice if you are not sure about compatibility. If you want to store two helmets and some extra gear without spending a fortune, this is your best bet.

Consider Alternatives If

If security is your top priority, the built-in lock may not satisfy your needs. Riders who want passenger seating should look at the Kolpin Helmet Box or Trunk and Lounger models instead, as this is purely a storage box without seating.

3. Kolpin ATV Rear Helmet Box – Best for Passenger Comfort

The Kolpin ATV Rear Helmet Box combines storage with passenger seating in a well-designed package. I have used this box extensively when riding with a partner, and the cushioned seat provides genuine comfort on longer trips. The 26-gallon capacity easily holds two adult helmets with room left over for gloves, goggles, and other essentials.

What sets this apart from basic storage boxes is the wraparound design. The arm cavities give your passenger somewhere to rest their hands, which reduces fatigue on extended rides. The rear access door makes it easy to grab items without having to climb off the ATV, which I found handy during hunting season when quick access to gear matters.

The construction quality matches what I expect from Kolpin. The roto-molded UV-stabilized plastic has survived multiple seasons without issues. My main gripe is that the latches can vibrate open on particularly rough terrain. I solved this by adding zip ties through the latch holes during aggressive riding.

Best For

This helmet box shines for riders who frequently carry a passenger. The combination of storage and comfortable seating makes it perfect for couples or families who share ATV adventures. The 26-gallon capacity hits a sweet spot between bulk and usability for most recreational riders.

Consider Alternatives If

If you ride solo most of the time, the extra cost for passenger seating may not be worth it. Riders who need maximum storage should consider the Trunk and Lounger model instead, which offers 31 gallons of space.

4. Black Boar ATV Rear Storage Box – Premium Lounger

The Black Boar ATV Rear Storage Box takes a different approach with its dual-compartment design. I really appreciate having two separate storage areas. The lower lockable bin provides 1.5 cubic feet of sealed storage for valuables, while the upper bin offers quick access to items you might need while seated. This split design works great for keeping frequently used items separate from secure storage.

Comfort is where this box excels. The 12-by-20-inch seat cushion is generously padded, and the lumbar support makes a noticeable difference on long rides. The angled backrest is more comfortable than the flat designs on many competing boxes. Two built-in cupholders are a thoughtful touch that my passengers have definitely appreciated.

Universal compatibility with tubular racks meant installation went smoothly on my ATV. The polymer construction feels durable enough for regular use, though it does not quite match the tank-like build of the Kolpin products. The integrated stainless steel lock is a nice feature, but like many ATV box locks, it is more of a deterrent than serious security.

Best For

This Black Boar model is perfect for riders who want easy access to certain items while keeping other gear locked away. The comfortable seating with lumbar support makes it ideal for long trail rides with a passenger. If you enjoy having drinks within reach, the cupholders are a practical bonus.

Consider Alternatives If

Riders on a budget may find better value in the Kolpin options. If you need maximum storage in a single compartment, the dual-bin design reduces overall space compared to single-box alternatives.

5. Guide Gear ATV Lounger Seat – Budget Hard Box

The Guide Gear ATV Lounger Seat offers solid value for riders watching their budget. This American-made box provides enough space for two helmets plus some extra gear. The cushioned seating and padded backrest deliver decent comfort for passengers, though the 90-degree backrest angle is not as relaxed as contoured designs.

Installation uses four U-bolts to attach to tubular racks, which is standard for this type of product. I did run into some challenges getting the box level on my ATV because the bottom is not completely flat. Adding some rubber spacers solved the issue, but it was an extra step I was not expecting. The extra-wide hatch opening makes loading and unloading gear easy once everything is mounted.

The heavy-duty UV-stabilized polyethylene construction should hold up well to sun exposure. I appreciate that the two latches include space for a padlock, letting me add my own higher-quality lock for better security. Just be aware that some users have reported quality control issues with warped doors affecting the seal.

Best For

This Guide Gear lounger is ideal for budget-conscious riders who still want reliable storage and passenger seating. The made-in-USA construction and lockable design offer good value at this price point. If you need a basic box that gets the job done without premium features, this fits the bill.

Consider Alternatives If

If you want something truly plug-and-play, the installation challenges might frustrate you. Riders who demand perfect sealing should look at higher-end options, as the door fit can be inconsistent between units.

6. KEMIMOTO ATV Storage Bags – Best Soft Storage System

The KEMIMOTO ATV Storage Bags offer a different take on ATV cargo management. This soft storage system provides a massive 76 liters of capacity spread across three compartments plus a dedicated cooler bag. I found the flexibility of separate bags useful for organizing different types of gear, and the included rain cover kept everything dry during an unexpected downpour.

The insulated cooler bag is a standout feature. It kept drinks cold for hours using the aluminum foil lining, which is perfect for day trips. The TPU water-resistant fabric feels durable and the zipper-free flap design means no stuck zippers to deal with. Reflective strips add a safety element for low-light riding conditions.

Assembly took me longer than expected. The three-piece design requires fitting structural pieces into pouches to give the bags shape. Once assembled, the soft breathable cushion and backrest provide comfortable seating. Just know that the bags tend to collapse when empty, so they work best when you actually have gear stored inside.

Best For

This KEMIMOTO system is perfect for riders who want maximum storage flexibility and an integrated cooler. The detachable design lets you customize your setup based on each trip. If you prefer soft bags over hard boxes for weight savings, this is one of the most capable options available.

Consider Alternatives If

If you want something you can mount and forget, the assembly process may be more work than you want. Riders who prioritize security should stick with hard-shell boxes, as soft bags are easier to cut into.

7. Tusk Trail-Runner ATV Rear Rack Bag – Best Budget Bag

The Tusk Trail-Runner ATV Rear Rack Bag punches above its weight class for the price. With 56 liters of total capacity spread across three compartments, this soft bag system offers impressive storage without the premium price tag. The removable cooler bag holds 8 to 12 cans, making it perfect for day trips when you want cold drinks waiting at your destination.

I really like the zipper-less design. Instead of zippers that can jam or break, this bag uses flaps with buckles for quick access. The molle attachment points on the outside let you customize your setup with additional pouches or accessories. The included water bottle holder is a thoughtful touch that keeps hydration within reach.

Assembly proved to be the biggest challenge with this bag. Getting the structural supports into the side pouches took some effort, and even then the walls bowed outward slightly. The padded seat is comfortable once everything is in place, but budget some extra time for the initial setup.

Best For

This Tusk bag is ideal for riders who want maximum features at a budget price. The combination of storage, cooler, and comfortable seating delivers exceptional value. If you are new to ATV storage and want to try a soft bag system without a big investment, this is a great starting point.

Consider Alternatives If

If you want something truly waterproof, the included rain cover helps but hard boxes offer better protection. Riders who struggle with assembly should consider pre-assembled options or hard boxes that mount directly.

8. Kimpex Outback 2.0 Trunk – Basic Rear Storage

The Kimpex Outback 2.0 Trunk delivers straightforward rear storage without unnecessary frills. This basic trunk fits two helmets and provides enough room for essential gear. At 31 pounds, it is light enough to remove easily when you need to use your ATV rack for other purposes. The passenger seating area offers decent comfort for the price.

Installation was one of the easier experiences I have had with ATV storage. The trunk mounts to the rear rack with basic hardware, and I had everything secured in under 20 minutes. The 42-by-28-by-17-inch dimensions provide a good balance between storage capacity and not overwhelming smaller ATV frames.

The plastic construction feels lighter duty than premium options like Kolpin. While it has held up fine for recreational trail riding, I would have concerns about long-term durability in harsh conditions. The lack of an integrated key lock is also a limitation if you need to secure valuable gear.

Best For

This Kimpex trunk is ideal for riders who need basic storage and passenger seating without paying for premium features. The lightweight design works well if you frequently remove your storage box. If you want something functional and straightforward, this delivers the essentials.

Consider Alternatives If

If you need built-in security, the lack of a key lock will be a dealbreaker. Riders who demand heavy-duty construction should invest in higher-end options from Kolpin or Black Boar for better long-term durability.

How to Choose the Best ATV Rear Storage Boxs?

Finding the right ATV rear storage box comes down to matching features with your specific needs. I have broken down the key factors to help you make an informed decision. If you also venture into muddy terrain, check out our guide on kinetic recovery ropes for mud extraction for when you get stuck.

Storage Capacity and Size

Consider what you actually plan to carry. If you need to store two helmets plus gear, look for boxes with at least 25 gallons of capacity. For hunting equipment, tools, or camping supplies, the 31-gallon options like the Kolpin Trunk and Lounger provide ample space. Measure your ATV rack dimensions before purchasing to ensure proper fit.

Material and Durability

Hard boxes typically use high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE). These materials offer excellent impact resistance and UV stability. Roto-molded construction tends to be more durable than injection-molded alternatives. Soft bags use water-resistant fabrics like TPU, which are lighter but offer less protection.

Weather Protection

Look for boxes with seamless hinges, foam gaskets, and gutter designs that channel water away from the lid. Water-resistant is not the same as waterproof. If keeping gear absolutely dry matters, prioritize boxes with proven sealing systems. Many soft bags include rain covers as backup protection.

Mounting and Installation

Most boxes use U-bolts to attach to tubular racks. Universal fit options work with most ATVs, but some may require modification for specific models. Consider how often you will remove the box. Soft bags with quick-release straps are easier to take on and off than hard boxes requiring bolt removal.

Security Features

Built-in locks provide convenience but are often not very secure. Look for boxes with padlock holes that let you add your own higher-quality lock. Hard boxes offer better security than soft bags, which can be cut open. For valuable gear, consider a box with a dedicated lockable compartment like the Black Boar model.
