Polaris RZR 4 XP 900/1000 Cab Enclosure (upper doors only) by SideXSide Enclosures

Polaris RZR XP 4 1000 / 900 / Turbo Upper Door Enclosure by SideXSide Enclosures

Close up the cab on your Polaris RZR XP 4 without giving up your factory setup. This SideXSide upper door enclosure works with the hard roof, windshield, and rear window you already run, adding heavy-duty ballistic upper doors to your 4-seater. It keeps wind, rain, dust, and trail debris out of the cab, and it goes on and comes off fast once you set it up. Made from tough ballistic material, this RZR 4-door cab enclosure is built to ride hard and hold up.

Before you order, remember to pick how you want your enclosure to attach in the drop-down menu.

Key Features

• Heavy-duty ballistic material built to take real trail use

• Sides wrap around your roll cage and across the top of your factory door
• Your choice of attachment: Velcro, self-adhesive snaps (no drilling), or pop rivet snaps (drilling required) — select in the drop-down
• Each window unzips from the bottom, so the door opens fully without unsnapping a thing
• First-time setup takes under an hour; after that, remove or reinstall in about a minute
• Comes complete with everything needed to install, plus a free storage bag
• Custom made in the USA

Good to Know

• Velcro and self-adhesive snaps are not guaranteed
• Velcro or adhesive applied over decals can damage them
• Velcro is sewn along most of the enclosure so you can place it where it works best — use small pieces instead of long strips for better hold
• We do not recommend trailering with the enclosure installed; trailering voids the warranty
• Backed by a 1-year warranty for quality and workmanship
