MasterTwill Fabric Replacement Tops for JK/JKU Jeep Wranglers are designed to fit over your factory Soft top bow system. Each top is made with our exclusive MasterTwill woven three layer soft top fabric that is both mildew and UV resistant. The MasterTwill fabric is extremely durable providing both sound absorbing properties as well as outstanding weather protection. This woven twill fabric gives your vehicle that up-graded fabric soft top look and feel found on the most expensive convertible tops . All MasterTwill Tops use press polished 40 mil ultra-clear windows that are DOT compliant and feature a 31% dark tint to keep interiors cool even in the hottest summer months. Unlike rolled glass that is used in low cost off branded soft tops, MasterTop windows do not distort your view and the 40 mil thickness ensures the glass lasts longer than other aftermarket soft top glass with thicknesses in the 20-30mil range. MasterTwill replacement soft tops can be enjoyed with the side and rear windows completely removed creating an open air Bimini top. Furthermore, high quality scoop count OE quality matching zippers allow for easy side and rear window replacements if you happen to damage a window. All MasterTop Early model JK and JKU (2007-2009 models) applications include the exclusive MasterTop conversion kit that turns your old style door surrounds into a cable style top design found only on 2010-2018 JK/JKU models. This unique kit makes the top fit tighter over the doors and makes the folding back of the front portion of the top easier. No more need to release the over door attachments to fold back your top! Our highly engineered custom designs provide a tight, weatherproof fit while ensuring a quiet comfortable ride. Custom fit design along with using superior quality zippers, MasterTwill fabric and 40 mil press polished glass makes MasterTop quality the best value in a soft top replacement.
