Trail Armor’s Rear Window Dust Shield kit provides the most effective barrier for keeping cargo, dust and debris out of the cab of your 2017 - 2018 RZR XP 1000. The upper rear windshield is made from ¼” thick (not 3/16” or 1/8”) clear polycarbonate, making it the strongest and most durable rear window on the market. Unlike some of the other rear windows on the market, Trail Armor’s Rear Window Dust Shield kit has a UV protective coating on the exterior of the window to inhibit yellowing. Additionally, instead of just fitting between the roll cage bars (leaving sizable gaps between the shield and the bars), Trail Armor’s Rear Window Dust Shield kit overlays the roll cage bars for a professional, tight fit as a cab back – essential when used as part of a full cab enclosure for those winter rides - and will not interfere with hard or soft tops. The bottom dust shield is made of ¼” black HMW haircell polyethylene and fits securely between the lower cage and the bed of your vehicle. It will not interfere with any bed function and will accommodate seat belt harness straps. Like all Trail Armor windshields, skids and debris shields, this Rear Window Dust Shield kit is cut with a CNC 5-axis router to ensure a smooth-edged, accurately cut product every time. Trail Armor’s Rear Window Dust Shield Kit for the Polaris RZR XP 1000 is easy to install and features Trail Armor's new fast clamps. Kit comes with all mounting hardware and detailed, photo-documented instructions. Please specify year and model as the bottom panel of the 4 seater is slightly different from the 2 seater. Also if your vehicle is the DESERT EDITION or if it has the POLARIS SIX POINT HARNESS, please specify using the drop down box. Also will not fit the Highlifter edition due to the snorkles.
