Product Details
Chevy Blazer 5.7L 1981, Powerforce™ Harmonic Balancer by Professional Products®. These dampers are the dimensional duplicate of the O.E. damper used on the 2V engine. If used on a 4V engine, the accessories (alternator, A/C, etc) will rotate 3% slower than stock. Normally this is not a significant amount. This is due to a slightly different diameter of the damper. These dampers do not have timing marks on them but do have a notch in the back rim of the damper indicating TDC.
