Lightweight Billet Crankshaft Pulley

Quadstar Tuning LLC

  • $215.00


These replace the factory rubber insulated damper that drives the serpentine belt on 6.5L diesels.  You'll never have to replace a pulley again after upgrading to this!  Weighing in a 2.2 lbs, they are 2 lbs lighter than solid aluminum pulleys.

Make your system 100% maintenance-free by coupling with the Fluidampr harmonic damper!  This pulley is also compatible with factory balancers, however.

Re-use the four factory 15mm bolts and torque to 35ft/lb during installation.

Direct replacement and upgrade for OE GM #12557345
