ACC Plymouth Sound Deadening & Insulation

Choose your vehicle application, then compare materials, coverage and options on each listing.

This collection has 16 ACC EVA sound deadening kits for Plymouth, mostly 1960s and 70s Mopar muscle and A-body cars. Each kit is pre-cut and goes down on the floor before the carpet.

Muscle cars

Kits cover the 1967-1971 GTX, 1968-1975 Road Runner, 1970 Superbird, 1966-1970 Satellite and Belvedere, and Barracuda kits for 1966-1974 and 1970-1974, plus the 1970-1974 Cuda. These cars are loud and hot inside, and a new interior with no insulation under the carpet makes that worse.

Valiant, Duster and Scamp

A-body coverage includes Valiant kits for 1967-1976 and 1970-1976, the 1967 Valiant Signet, the 1970-1976 Duster and the 1971-1976 Scamp. These are 4-piece kits.

Fury and Gran Fury

Full-size cars get 6-piece kits: the 1965-1974 Fury, 1970 Fury Gran Coupe and 1972-1977 Gran Fury.

Common questions

Will a Dodge kit fit my Plymouth? Many Mopars share floors, but buy the Plymouth listing for your car so the fit is right.

Do I remove the old jute? Yes. Jute holds moisture and leads to floor rust. Pull it, clean the floor, lay the EVA, and install the carpet. Kits are made in the USA by Auto Custom Carpets.

Every kit on this page is about $124, and all ACC products ship free.
