Sound Deadeners - OEM-Style Insulation Kits Made in the USA
Restore your vehicle’s interior with precision-fit automotive sound deadener kits manufactured to OEM specifications for classic cars, trucks, and SUVs. Each kit is custom-cut or molded to match the original floor pan, firewall, and interior contours of your vehicle—delivering a factory-correct fit and measurable reduction in road noise, heat transfer, and vibration.
Our sound deadener kits are available in three materials to match the original factory application: EVA (Ethylene Vinyl Acetate), a flexible foam-like material ideal for floor and firewall coverage; Mastic with Pad, a heavyweight asphalt-based compound laminated with a foam layer for superior damping in high-vibration areas; and Jute, the classic fiber-based padding used as original firewall insulation in many vintage applications. Multi-piece kits are engineered to cover the complete passenger area, firewall, and transmission tunnel for thorough coverage in a single order.
