Fits 1988-1998 Chevrolet/GMC GMT400 Trucks and SUVs. The BROTHERS Trucks floor mats are a great looking and practical add-on for your GMT 400 (OBS) pickup and SUV's! These mats, featuring the trademarked "GM" logo, are based on the nearly impossible to find originals and are officially licensed by Chevrolet. They are modeled to provide all of the same dimensions and detail as the factory originals. They are made from extremely durable, easy-to-clean PVC rubber, providing protection for your carpet and insulating your interior from heat and road noise. Backed with anti-slip spikes, these floor mats won't slip and slide around while you're out cruising.
