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

New ATI racing damper for your L6 or L4 engine (choose in drop down).  This balancer is intended for racing but can be used on strret applications if the pulley will fit your application.  Factory dampers and non-dampened pulleys offer no protection to high performance engines. ATI Super Damper sport compact harmonic balancers provide the balanced dampening of torsional crankshaft vibrations at all rpm levels.  The smooth-shell race version dampers are designed for high performance race use. Both dampers come with laser-etched timing and exceed SFI 18.1 Safety Certification standards for competition use.   

Aluminum pulley for L4 balancer sold separately.  Aluminum pulley is 6.6" diameter.

L6 fits L24, L26 and L28

L4 fits L16, L18 and L20B (no V belt pulley)

6.325" damper diameter, V belt pulley is 2.75" diameter (L6)

*Longer balancer bolt will most likely be required for the ATI damper over stock.  PT# 800-1984.
