10 Best ATV Rear Storage Boxes 2026 in the United States

The Black Boar ATV Rear Storage Box & Lounger is an interesting option for ATV enthusiasts looking to combine comfort with functionality. It offers around 2 cubic feet of storage, divided into a secure lower bin and an easily accessible upper bin, making it suitable for carrying essentials on your rides. The mounting system is user-friendly, compatible with most tubular racks, and comes with all the necessary hardware, which simplifies installation.

One of its notable strengths is the integration of a comfortable seat cushion along with lumbar and back support pads, allowing riders to rest during breaks. Additionally, it includes two cupholders, which is a thoughtful feature for hydration on long trails. The construction from durable polymer ensures that the unit is lightweight yet strong enough to withstand regular use.

However, there are some drawbacks to consider. While the storage box is weather-resistant, it may not be completely waterproof, so users might need to be cautious during heavy rain. Also, since the accessory is designed to be used only when the vehicle is stationary, it limits its convenience during active rides. Although the built-in locking system adds a level of security, it’s worth noting that some users might prefer more robust options for protecting their belongings.

The TCMT 95L Rear Seat Rack Trunk is a roomy storage box for your ATV, offering a solid 95 liters of space that can hold quite a bit of gear or luggage. It's made from heavy-duty LLDPE, a durable plastic known for being tough and weather-resistant, which means it should stand up well to rain and rough outdoor conditions. The box has a universal fit, so it can work with most ATV models, making it versatile for different riders. Weighing about 24 pounds, it’s sturdy but not overly heavy.

The smooth exterior is easy to clean, and it offers convenient access for loading and unloading. This storage box is a practical choice if you need a durable, spacious container for carrying gear on your ATV, especially if you value weather resistance.

It is advisable to verify mounting compatibility with your ATV’s rack and consider adding your own lock if you plan to leave valuable items inside.

The Polaris Lock & Ride Rear Audio Cargo Storage Box is a solid choice for Sportsman ATV owners looking for a hard-shell storage solution with the added bonus of built-in audio. Its plastic material keeps the box lightweight at 31 pounds while offering decent durability and water resistance, protecting your gear and the integrated speakers from the elements. The storage box is fairly spacious with dimensions of 44.5 x 21 x 14.5 inches, fitting well on the rear rack using Polaris’s Lock & Ride mounting system, which makes installation straightforward and secure. However, if you have a Sportsman 850 or 1000 model, you’ll need to remove some stock tie-down points for fitting, which might be a minor inconvenience.

A key highlight is the integrated audio system featuring dual Rockford Fosgate 6.5-inch speakers with Bluetooth connectivity and a 150W amplifier, perfect for those who want to enjoy music while riding without extra gadgets. The audio system requires an additional Rear Audio Harness (part 2889070) which adds to the cost. The sealed lid keeps the speakers safe from rain or dust. Access to your gear is easy thanks to the rear rack mounting and the lid design. This storage box suits ATV riders who want reliable storage combined with quality sound, though it might be less ideal if you prioritize maximum security or don’t need audio functionality.
