This fully custom-molded die cut system is sold as a separate front and rear kit 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 is 100% waterproof, dries quickly, resists all harsh chemicals, and will not stain, stink, mold or mildew. The 1/4-inch thick 100% polypropylene foam insulates your interior from road noise and heat. BedRug liners vs. spray-in liners? Quick install and removal - no removal of seats or center console necessary. Heat and noise insulation and removal or grinding of factory paint not necessary.
