Stow your gear without fear of the elements and ride off to wherever adventure takes you! This locking ATV cargo box has ample storage space to hold anything you need on the trails. And, with a built-in cushioned backrest, you can ride in comfort!


Secure, key-locking design

To prevent unauthorized access, this ATV cargo box has two latches that come with a key lock and two keys. The unobtrusive black finish doesn’t draw attention to the locking mechanism or latches.

Weather seal in the lip prevents moisture from entering

The tongue-in-groove lid design features a weather strip to seal the cargo box and keep rain, snow and moisture at bay. Your gear will stay dry no matter what.

Cushioned backrest for lumbar passenger support

If your ATV is able to support a passenger, this cargo box adds to their comfort with a cushioned backrest and jutting elbow rests.

More Information

The cushioned backstop of this box keeps you comfortable even over rugged terrain. Rear reflectors improve nighttime visibility for low-light rides. It’s the last ATV cargo box you’ll ever need and everything you expect from a rack-mount, hard-form storage container.

The durable high-density polyethylene can take a beating and keep on going. This box is waterproof, crack and warp resistant, and sturdy—not to mention secure. The key-locking lid protects valuable items from theft, and the box can be permanently mounted to the rear rack of your ATV with the four included U-bolts (requires drilling into box).
