Replace that old worn out Rear Soft Top window on your factory original Jeep Soft Top with a window replacement from MasterTop. Since MasterTop uses only OE quality Zippers, fabric and 40 mil window glass in their tops, these zip-in windows are a perfect replacement to up-grade your current soft top. Each window is built to factory specifications making the replacement of your windows a breeze. Each window has durable 40 mil tinted window glass with 31% tint to keep the heat out. All use ultra-high quality YKK scoop count zippers which should match your current zipper down to the exact tooth count level. The Vinyl replacement windows use 28oz black Diamond, US made Sail Cloth fabric that is an exact match to what you currently have on your vehicle. Each replacement window includes a rear window only. Before ordering confirm you have a factory original soft top and measure your current rear window. 07-09 JK Wrangler rear windows measure approximately 44” across. 2010-2018 JK Wrangler rear windows measure approximately 51” across. NOTE: These Windows will only work with Mopar Factory Soft Tops. Look in the corner of your current soft top window for the Chrysler or Mopar logo embossed in the window to ensure you have a factory soft top.
