    • Will work on 2026 Mud Edition if modified
I was able to modify the box to have it fit the Mud edition. I removed the rear cargo rack and used it as a template to drill two holes. I then installed the front normally as designed. The rear I had to remove the inside spacer to the outside and it locked the unit in. I am pleased with the product as it seems well built. ... show more

Perfect for our Polaris 570. Easy to attach too!! No drilling necessary.

    • Almost great
I don't like the hinge and it could be taller. Otherwise it's fine. Fits 570

    • Cargo RV box
This box fits perfectly on my new Polaris 4 wheeler. Has lots of space for road essentials. I’m not worried about the box being stolen off the rv because of the way it’s attached

    • No good!!
Holes are not drilled correctly! Still had to end up drilling myself! Had I known that, I would've went with a much cheaper option that offered way more than this overpriced plastic container! Thin cheaply made!!!

    • Very poor quality!!!
Wrong hardware!!!! Poorly packed. Soft plastic. A very expensive plastic box.

    • Nice storage add to the Polaris 570.
Box looks good on the 570. One big compartment which is good for larger items but not good for organizing smaller items. Easy to install with one clamp that goes under a small shelf in the unit that’s a bit challenging. Great add to our ATV.
