Fluidampr - Harmonic Balancer - Drill Pin Kit - 2001-Present GM/Chevy Duramax 6.6L - Kit 300019

For high performance 5.9L and 6.7L Cummins® engines that exceed 3,500rpm, Fluidampr recommends the damper be pinned to the crankshaft.  Highly recommended for drag racing and sled pulling.  The current Fluidampr drill pin kit (p/n 300002) is upgraded from a roll pin to a stronger .0005” press fit steel dowel pin(s).  New to the kit is a smaller 7.7mm drill and reamer tool.  A drill fixture is included for accurate alignment with the damper’s pre-drilled pin hole(s).

Part number – 300002.
