This fully custom-molded die cut system provides a rugged spray-in look in minutes without the need of any labor intensive prepping or removal of seat brackets or center console. Sold as a separate front and rear kits, individual pieces can be quickly removed and hosed off after a long day on the trail if desired. The BedTred material is 100% waterproof, wont absorb water, and will never stain, stink, mold or mildew; dries quickly and resists all harsh chemicals. The 1/4-inch thick 100% polypropylene foam insulates your interior from road noise and heat. Bedrug does not recommend additional mats and liners because the nibs on the back of mats or liners will not grip, but rather slide on the BedTred material.
