This 100 waterproof, fully custom-molded die cut system is sold as a combination kit containing the front and rear kits and installs quickly without the need to remove any seat brackets or the center console. Individual pieces can be quickly removed and hosed off after a long day on the trail if desired. The BedRug material dries quickly, resists all harsh chemicals, and will not stain, stink, mold or mildew. The 1/4-inch polypropylene foam kit, with provided heat shields, insulates your interior from road noise and heat.
