ATI SUPER HARMONIC 7" RACE DAMPER K-SERIES ACURA RSX DC5 HONDA CIVIC SI FD2 K20

Description

ATI Performance Products, Inc. is proud to introduce its renowned Super Damper for the Honda K-series engine racing applications. Unlike unbalanced underdrive pulleys, which offer no protection to high performance engines, the ATI Super Damper provides balanced dampening of torsional crankshaft vibrations. 

ATI Race dampers allow for the mounting of a dry sump oiling drive gear to the front of the pulley. ATI’s 7” and 6.325” race versions are built with all-out power in mind. You won’t find any provisions for a drive belt here. Hub has laser engraved 360° timing marks on outer damper shell. 

All K-series Super Dampers exceed SFI 18.1 Safety Certification and are approved for NHRA & IHRA competition.
