Dynamat SuperLite

Sound Deadening Without the Weight Penalty

Most sound deadening buys quiet with thicker, heavier material. Lightweight sound deadening takes a different route: it damps panel vibration and blocks road noise while keeping weight off the build. 

Dynamat SuperLite is a USA-made, high-efficiency sound-deadening material designed for applications where every pound counts, from race cars to large-area coverage in daily drivers.

How SuperLite Saves Weight

Standard butyl mats damp vibration with a thicker, heavier build. That works, but across a full build, the pounds add up. Lightweight sound-deadening material like SuperLite delivers strong vibration control while running 30% lighter and 30% thinner. 

SuperLite prioritizes weight efficiency, so on thin, resonant panels, it controls ring and drum without loading the chassis. For weight-sensitive sound-deadening jobs, that balance is exactly what you need. You quiet the car without giving horsepower back to the scale.

Performance and Race Builds

When you’re chasing lap times, mass is the enemy. Every pound counts, so sound deadening for race car interiors must control resonance without undoing the weight savings you fought for elsewhere. Where heat is part of the problem, pair it with a thermo-acoustic layer like Dynaliner.

SuperLite treats large areas, floors, firewalls, trunk pans, and roof skins at a lower weight cost than heavier mats, so you can cover more of the cabin inside a tight weight budget. For weight-conscious street and track builds that watch the scale as closely as the audio, it lets you have both.

Choosing SuperLite vs. Xtreme vs. ProX

SuperLite is the right call when weight is the priority. If maximum damping takes precedence, move up to Xtreme or ProX. 

Dynamat Xtreme is the flagship standard for doors, floors, and full-cabin treatments where you want more vibration control per square foot. For the toughest jobs, big flat panels, work trucks, and heavy-gauge metal, heavy-duty sound deadening with Dynamat ProX delivers the highest mass and the greatest damping. 

Building a system and still watching weight? Pair SuperLite with the right coverage for car audio sound deadening that stays clean and controlled. The same weight-saving approach also works for marine sound deadening on boats and RVs where added weight can affect performance.

Product Guide: Tri-Pack vs. Bulk Pack

Two SuperLite packs cover most builds:

• Dynamat SuperLite Tri-Pack: Sized for targeted jobs like doors, trunk lids, and smaller panel sets where you want measured coverage
• Dynamat SuperLite Bulk Pack: Built for large-area work, including full floors, firewalls, and complete interior treatments where you're covering serious square footage. 

Match the pack to the surface area you're treating, buy the coverage you need, and install it right the first time. If your priority shifts to maximum damping on large, flat panels rather than weight savings, that's when it's time to move up to Xtreme or ProX.
