Product Description

The Fluidampr 300019 Drill Pin Kit provides a precise and secure method for pinning the harmonic damper to the crankshaft of a 6.6L Duramax engine. High-output diesel engines often experience intense torsional forces that can cause a press-fit damper to shift or slip over time. This kit solves that problem by enabling the installation of a hardened dowel pin, locking the damper firmly into place for improved reliability and long-term performance.

Designed specifically for the Duramax platform, the included drill fixture guides the bit perfectly to ensure correct alignment and depth. Whether you're upgrading to a Fluidampr performance damper, rebuilding a worn engine, or preparing a heavy-duty work truck for demanding use, this kit ensures a stable mechanical bond between the crankshaft and damper. It's a simple yet essential upgrade for anyone seeking maximum durability from their diesel powerplant.
