When upgrading the harmonic damper on a Duramax diesel, securing the damper-to-crankshaft connection is essential to prevent slippage under heavy torque and high-RPM conditions.

Designed for performance shops and diesel enthusiasts, this kit includes a precision drill fixture, hardened drill bit, and roll pin to ensure accurate alignment and secure fitment. Highly recommended for tuned or towing Duramax trucks running a Fluidampr or aftermarket performance damper.
