This is a genuine factory style replacement product with full manufacturer warranty & support. Constructed from the upgraded specialty fabric that stretches for fast installation and returns to its original shape for tautness. It allows you to open your tailgate without opening the rear window. Features DOT approved windows, over-sized zippers, and factory-spec velcro, thread, webbing, and door seals. Sierra Offroad replacement soft tops require use of your factory-original top frame and hardware. It may be used with aftermarket hardware designed as a factory original replacement. Designed and manufactured to directly replace the factory original soft top and requires a factory original or factory style frame. Diamond patterned vinyl was the original material on the 2003 through 2006 Wrangler TJ.
