Due to high demand, tuning turnaround is a minimum of 2 weeks. Current lead times on custom built turbos is ~1 month. Please plan accordingly. We thank you for your support of the finest parts available for the 6.5L Turbo diesel platform!
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!
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
