The ATI Performance Products ATI917116 is part of ATI's renowned Super Damper Standard Series of harmonic balancers — the only crankshaft dampers engineered exclusively for high-performance engine applications. Designed to eliminate destructive torsional crankshaft vibrations, this damper protects rotating assembly components and helps maintain power output across the RPM range.

• SFI 18.1 certified — meets or exceeds SFI specifications for sanctioned racing competition including NHRA and IHRA
• Steel inertia weight retained within inner and outer shells available in aluminum or steel construction
• Computer-machined O-ring grooves — dyno-tested durometer O-rings retain the inertia weight precisely for each application
