New SFi approved harmonic balancer for Datsun 240Z, 260Z, and 280Z, 1970-1978 and 510 68-73.  Fits all 1968-83 L series engines.  This Sfi damper is designed for higher RPM usage. This is a single groove pulley, so will not work with A/C, however it has 2 thread inserts on the front to add a pulley.

*  These balancers have been tested and have the correct fitment onto the crankshaft.
