Description

The HushMat 617483 is a custom vehicle door sound deadening and insulation kit designed for 1971-1976 Cadillac 70 Series Sedans. This kit utilizes HushMat Ultra, a proprietary adhesive technology that offers a peel-and-stick application without the need for special tools or harmful chemicals. It effectively reduces road noise, wind noise, and vibrations from the doors, creating a quieter cabin environment. The material is also a thermal insulator, contributing to a more comfortable ride by reducing heat.
