Weathertech TechLiner Tailgate Liner; Black (07-12 Sierra 3500 HD)Find parts that fit my vehicle

Precision Protection for Your Tailgate. The TechLiner tailgate liner perfectly matches the contours of your Sierra’s tailgate, creating a rugged barrier against scratches, dents, and chemical spills. Its raised lip traps water, mud, and loose cargo, preventing damage to the painted surface. The textured TPE polymer provides a stable, non-slip platform for loading gear, while its resistance to UV rays and automotive fluids ensures the liner retains its shape and color over years of exposure.

Durable, No-Tools Install. Engineered for a snap-in fit, the liner mounts using your factory tailgate latch—no drilling or adhesives are required. The flexible yet sturdy material bends slightly for insertion and then springs back into place, locking securely. When cleaning is due, simply hose off or wipe down the surface and reinstall.

Installation. Open the tailgate, insert the liner into the top edge, press down along the profile to seat into the latch and side channels, then close the tailgate to lock the liner in place.

Application. The WeatherTech TechLiner Tailgate Liner; Black fits 2007–2012 GMC Sierra 3500 HD tailgates.
