Notes
These are damper shell assemblies only - without a hub

A standard length crank bolt is used and the mandrel bolts to the 3 pulley mounting holes
This eliminates the 4" - 6" long bolt that is ineffective in retaining torque

Tunable, rebuildable, and extremely efficient at ALL RPM
Laser engraved 360° timing marks
