ATI Super Damper - C6 ZR1/LS9 (14% OD)

ATI Performance Products, Inc. is proud to introduce its Super Damper® for LS9 engines including the new 2009 Supercharged Corvette ZR1. ATI offers the OEM replacement sized damper (P/N 918634) along with the overdrive damper. The overdrive damper (P/N 918624) for the LS9 small-block, V-8 engine is designed with a 14% overdrive and is bolted in the OEM location. Factory dampers and non-dampened pulleys offer no protection to modified engines that produce more HP than stock. The ATI Super Damper® provides balanced dampening of torsional crankshaft vibrations through all RPM ranges. This damper exceeds SFI 18.1 Safety Certification, for competition use.

ATI Performance Products, Inc., located in Baltimore, MD, specializes in producing and maintaining high performance products for street and strip applications. Over the years ATI has earned a reputation for its cutting edge technology, attention to detail, and rigorous testing under race conditions. By staying true to these basic principles, ATI has built a loyal customer base many of whom still use parts purchased from ATI in the 1980's.

The patented ATI Super Damper is the only crankshaft damper designed exclusively for high performance Chevy engines.
