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 2014 - 2016 Polaris Sportsman ACE 325 and 570. 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. 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. With Trail Armor's quick clamps, this kit is easy to install/remove and comes with all mounting hardware and detailed, photo-documented color instructions.
