Description Your 1988-1999 GMC Sierra Extended Cab was built to work hard, and the WeatherTech All-Weather Front Rubber Floor Mats in Black match that same no-nonsense work ethic. Manufactured from an advanced Thermoplastic Elastomer (TPE) compound, these front mats provide the toughness and flexibility needed to protect your truck’s front footwells against years of harsh use.
