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 Polaris 2019 - 2021 RZR 4 XP Turbo S,  2019 - 2021 RZR 4 Turbo S Velocity, 2018 - 2021 RZR XP Turbo S, 2019 - 2021 Turbo S Velocity 2021 RZR XP Turbo S  and RZR 4 XP Turbo S Lifted Lime LE. This 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. 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 2019 - 2021 RZR 4 XP Turbo S,  2019 - 2021 RZR 4 Turbo S Velocity, 2018 - 2021 RZR XP Turbo S, 2019 - 2021 Turbo S Velocity 2021 RZR XP Turbo S and RZR 4 XP Turbo S Lifted Lime LE is easy to install and features Trail Armor's fast clamps.
