6-3/4" 400 Small Block Chevy Harmonic Damper (Ext.)

Part # 80001


Quick Overview

These dampers are 6.75" in diameter and approximately 1-1/8" thick.These are our most popular dampers for internally balanced small block Chevys. They both have 60° of timing marks with engraved marks every 90°. They are dimensionally identical to a stock 6-3/4" damper.



6-3/4" 400 Small Block Chevy Harmonic Damper (Ext.)

This unique design damper is for use on externally balanced small block Chevy engines. This would typically include 383 and 400 cid assemblies. Only a few damper manufacturers offer a small 6-3/4" damper for these engines and those dampers are usually very expensive. Note that although this model damper features a bolt-in counterweight, the damper cannot be used without the weight. Due to the windows cut in the front face of the damper, if the counterweight is removed, the damper is still not a neutral balance damper. If you need a neutral balance 6-3/4" damper, use our 80000 or 90000 models.
