1973-87 Square Body Sound Mat Sound Deadener & Heat Insulating Kit 36sq ft

Your Square Body Chevy or GMC truck may look great on the outside, but it should sound and feel just as good on the inside using our 1973-87 Square Body Sound Mat Sound Deadener & Heat Insulating Kit 36sq ft. Designed to dramatically reduce road noise, vibration, and heat transfer, making your classic truck quieter, cooler, and more comfortable to drive.

This kit includes 14 high-quality sheets made from 80 mil thick damping material, offering excellent sound control and thermal insulation. The advanced Bmastic formulation is engineered for automotive use and delivers professional level performance without the high cost of similar products.

Installation is simple and clean thanks to the peel and stick backing. Just trim to fit, remove the protective paper, apply to a clean surface, and press or hand roll for strong adhesion. No sprays, no mess, and no special tools required. While a roller is recommended, it is not included.

One full kit will cover most of the cab floor and still leave extra material for the doors, back cab wall, and roof strips. If you plan to insulate additional areas such as the engine compartment, bed sides, or firewall, additional material may be needed.
