Fluidampr Harmonic Damper Drill Pin Kit For 89-18 Dodge Ram Cummins 5.9L/6.7L

When upgrading or replacing the harmonic damper on your Cummins-powered Ram, securing the crank-to-damper connection is critical — especially on high-RPM or performance builds. The Fluidampr Drill Pin Kit provides reinforced mounting support by adding roll pins between the damper and crankshaft to help prevent slip or shearing under extreme torsional loads.

Designed for engine builders and diesel enthusiasts pushing beyond factory RPM limits, this kit includes everything required: drill fixture, hardened drill bit, and roll pins. Compatible with both Fluidampr performance dampers and OEM units, ensuring trusted reliability on modified tow rigs, sled pullers, and race setups.
