The aluminum shell has an outer diameter of 5.5 inches. It comes with 4 and 5 serpentine groves and a bolt on power steering pulley.

The ATI Super Damper is the only damper designed exclusively for high performance engines that are rebuildable and tunable. Extensive dyno and on track testing by ATI has proven the Super Damper far superior to all other designs time and time again.
