Billet Crankshaft Pulley

Leroy Diesel

  • $165.00


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!

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

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

Current inventory is all black anodized aluminum, and will be for the foreseeable future. Direct replacement and upgrade for OE GM #12557345
