1973-87 Square Body Chevy & GMC Truck Standard Cab Foil Heat Sound Deadener Insulation, All Humps

Make every drive in your Square Body Chevy or GMC truck more comfortable with this 1973-87 Square Body Chevy & GMC Truck Standard Cab Foil Heat Sound Deadener Insulation, All Humps. Designed to fit all standard cab floor pans, this insulation works with small hump and large hump floors, as well as 2WD, 4WD, manual transmission, and automatic transmission applications.

Each insulation pad is pre-cut for an easy installation and features 3/8-inch-thick insulation bonded to a reflective aluminum foil layer. The foil helps block radiant heat from the engine, transmission, exhaust system, and road surface, while the insulation reduces engine noise, road noise, and floor pan vibration for a noticeably quieter ride.

Installed beneath your carpet or flooring material, this insulation helps keep the cab cooler during warm weather and warmer during colder months. By reducing noise and vibration, it also makes conversations inside the cab easier and creates a more enjoyable driving experience whether you're cruising, working, or restoring your classic pickup.

Installation is simple. Test fit the insulation first, then place it on a clean, dry floor pan. Minor trimming may be required depending on your application. A few spots of spray or weatherstrip adhesive are recommended to keep the insulation in position while installing the carpet.
