Show original supplier description

The ATI Performance 918434 is a patented Super Damper harmonic balancer specifically designed for high-performance Chrysler, Dodge, and Mopar engines, including the new HEMI. It exceeds SFI 18.1 specifications and is built for both racing and street driving applications. Constructed with a steel inertia weight, the Super Damper is available with either aluminum or steel shells. The inertia weight features either six (2-ring design) or eight (3-ring design) computer-machined grooves designed to retain proper durometer O-rings, which have been dyno-tested for each specific application. The damper also boasts laser-engraved timing marks for precise tuning and is tunable and rebuildable for long-term efficiency at all RPMs. This particular model, the 918434, features a 7.48-inch diameter, 4% overdrive, and an aluminum shell. It is intended for non-VVT 5.7L Hemi engines found in Dodge Ram 1500, 2500, and 3500 trucks, as well as Durango and Aspen models from 2003-2008.
