Description

The ATI Super Damper is a patented harmonic damper designed to eliminate torsional crankshaft vibrations. It exceeds SFI 18.1 specs and is OEM equipment on ZZ572 GM Crate Engines. It is tunable, rebuildable, and highly efficient at all RPMs, featuring laser-engraved timing marks. The inner and outer shells are available in aluminum or steel and contain a steel inertia weight with computer-machined grooves to retain proper durometer O-rings. This specific damper is designed for LS7 and LS9 DRY SUMP engines with a 6-rib and 4-rib configuration.
