Lightweight Billet Crankshaft Pulley
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.
