80001 6-3/4" 400 Small Block Chevy Harmonic Damper

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