Description

The HushMat 622642 is a firewall deadener and insulation kit designed for the 1964-1967 Chevrolet Chevelle. This kit aims to reduce thermal transfer from the engine, headers, and exhaust into the vehicle's interior, making for a more comfortable ride year-round. Its self-adhesive backing allows for an easy peel-and-stick installation without the need for special tools or expertise.
