ATI Super Dampers The preferred damper of quality drag race and endurance engine builders!

ATI Super Damper Why the Super Damper? It's the ONLY damper to provide engine protection and performance Designed specifically for high RPM engines All but eliminates worn parts and timing problems The "2 dampers in 1 diameter" design is fail-safe Tunable in the field, rebuildable and extremely efficient at all RPM's Available for virtually any engine application

The inner and outer shells are available in steel and in light weight aluminum to contain the steel inertia weight. The inertia weight has six (2-ring design) or eight (3-ring design) computer machined grooves to retain the proper durometer O-rings (dyno tested for each application). O-ring life has been tested to over 3 million cycles in Winston Cup competition and 10 years in drag racing engines. The unit is rebuildable to new specifications by installing new O-rings. Extensive dyno and on-track testing has proven the Super Damper™ far superior to all other designs, especially on engines that turn over 5000 rpm, and is used by every Winston Cup engines builder. Shells are black zinc chromate finished and come with laser engraved 360-degree timing marks. Exceeds SFI 18.1 specs.
