Rear ATV Box for Polaris Sportsman XP 450/570

This rear storage box is custom-designed for the Polaris Sportsman XP 450 and 570 models, offering the perfect balance of functionality, comfort, and style. Taking into account the specific geometry of the rear rack, the box mounts seamlessly—without overhanging the sides or interfering with the rider’s comfort.

Thanks to its ergonomic construction, the case features a built-in soft backrest, providing additional support during long rides. Its ribbed design not only reinforces the structure for maximum durability but also blends harmoniously with the modern look of the quad.

Installation is simple and tool-free. The included 4 quick-release fasteners allow the box to be mounted or removed in under 30 seconds—just align with the factory rack holes and tighten by hand.

The 145-liter capacity gives you plenty of space for helmets, tools, or supplies, while two secure metal locks with keysensure your belongings stay protected. A rubber gasket seal between the lid and body keeps out dust, moisture, and mud, making it reliable even in extreme off-road conditions.
