Durable RZR Trail 900 Upper Doors It™s possible to have a good time when you™re exposed to the elements, but your odds are way better when you have excellent upper doors. With SuperATV™s Primal Soft Cab Enclosure Upper Doors installed on your Polaris RZR Trail 900, you get versatile protection that™s tough enough to keep the elements out. Plus, they™re compatible with our roofs, windshields, and lower doors so you can make the ultimate cab enclosure. Made with Pel-Tek Technology Punctures, abrasions, and mildew are no match for these upper doors. We make them from PVC-backed polyester that utilizes our innovative Pel-Tek technology. This makes the material stronger than what you can get elsewhere. To give these doors a professional finish, we use a premium stitching technique and bind the edges. They™re also CNC cut to prevent stretching over time. Easily attach them to your machine using heavy-duty Velcro and durable snaps. We also include cinch straps that will keep your doors firmly in place while trailering. Double Polished Vinyl Gives You Great Clarity There™s no such thing as too much visibility when you™re behind the wheel. That™s why we put so much time and effort into designing the perfect windows for these soft doors. The vinyl is double polished for exceptional clarity and UV resistant to prevent cracking or yellowing over time. Adapts to Changing Conditions Wild swings in weather can make your ride uncomfortable if you™re not ready for them. Luckily, our upper doors are ready for anything. The window uses heavy-duty, snag-free zippers to roll up on the fly. They can be secured with flaps and robust snaps to keep them safe from mud and debris. You can also remove the window completely without removing the whole upper door. These doors will keep you one step ahead of the weather. Make It a Full Cab Enclosure Need to take your protection over the top? Add a roof and windshields to seal your cab and keep all of the elements out. With a full cab enclosure, bad weather won™t ruin your ride.
