Description

ATI has added a crankshaft damper for the earlier 4G63s to their lineup, designed for higher hp and high-rev applications.

Fits 4G63/4G64 engines in the 1990-1999 GVR4 and DSM cars.

Replaces both the OEM harmonic balancer and the crankshaft timing/balance shaft sprockets.

Please note that these are 12% larger than the OEM damper at 6.325″ diameter, and the timing belt cover will have to be slightly trimmed to clear the ATI inner hub diameter.
