SoundSkins

Give your Sierra's sound system a leg up in the fight against road noise with this GMC-specific SoundSkins sound-deadening kit. Designed to perfectly fit each door of your 2014-18 GMC Sierra Crew Cab trucks, each pre-cut panel of 3-layer acoustical dampening material limits the noise getting into your car and improves the acoustical properties of the doors by reducing vibration. SoundSkins' self-adhesive backing makes application easy and provides a long-lasting hold.
