Polaris RZR 4 900 Rear Seat Conversion Kit

Hauling gear in a four-seater RZR gets messy fast—loose stuff slides around, beats up your floorboards, and you can't keep anything organized. This rear seat conversion kit swaps out your back seats for tough UHMW plastic panels that give you a flat, secure cargo bed. It's also perfect if you want to bring your dog along for the ride.

What You're Getting

The kit includes two 1/2-inch UHMW panels. You can replace just one seat if you want to keep the other, or pull both out and get a full flat bed. Both panels bolt straight down to your existing seat base—no frame modifications needed. The panels are molded with ratchet strap notches built in so you can lash down cargo without fumbling around looking for tie-down points.

SuperATV also threw in pop-out access hatches so you can still reach down into your floorboards to stash smaller items underneath. And since the panels are cut around your seatbelt paths, your existing belt system stays functional—handy if you're traveling with a dog and want to use a seatbelt harness to keep them secure.
