Harmonic Balancer Damper Crankshaft 240Z 260Z 280Z 280ZX 510

New harmonic balancer for Datsun L series engines 4* and 6 cylinder 1968-83. Stock replacement performance balancer.  This balancer is a 2 groove design but the outer pulley can be removed for cars running only 1 belt.  Small pulley diameter is 5", large pulley is 7.5".

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

The diameter of this balancer may vary from the balancer on your engine and may require different belt lengths than what you currently have.

*L series 4-cylinder engines in the 510 can use this balancer but will require changing other components over to 240Z alignment (water pump, pulley. alternator bracket).
