Kill the rattle, drone, and heat — butyl sound deadener that makes an old Squarebody ride like a quieter truck.

This is DC Audio butyl sound deadener, a vibration and heat control kit built to quiet down a noisy cab. Old trucks have a lot of character — and a lot of noise. Road vibration, exhaust drone, tire roar, rattling door skins, and heat soaking through the floor are all part of the Squarebody experience. This kit cuts all of it down.

Lay it on your doors, floor, roof, and firewall and you'll feel the difference — less rattle, less drone, less heat, and noticeably better sound from your speakers because they're no longer fighting a buzzing sheet-metal panel. It's the foundation of any serious audio install and a massive comfort upgrade on its own. Available in a 36 sq ft single pack or a 72 sq ft double pack for a full cab.

Why It Works

• Butyl construction — quality vibration damping that stays put and doesn't melt off like cheap asphalt mats.
• Kills rattle & drone — quiets door skins, floors, and panels against road and exhaust noise.
• Heat control — helps block heat soaking through the floor and firewall.
• Better audio — speakers sound cleaner when the panel behind them isn't buzzing.
• Sized for the job — 36 sq ft single pack or 72 sq ft double pack for a full cab.
