Fluidmaper has developed two high performance parts to make sure this damper stays attached to your engine crankshaft. A diamond-impregnated friction washer to create a secure mating surface between the high performance viscous diesel damper and the crankshaft. This Friction Washer is designed for use with the Fluidampr High Strength Bolt Kit. Both of these Duramax retention devices can be purchased in one kit as the Fluidampr 300010 2001-2018 GM Duramax 6.6L High Strength Bolt Kit. This Duramax mounting kit ensures proper mounting and provides the additional piece of retention helps ensure your viscous performance diesel damper will stay in place.

WARNING: THE FAILURE TO USE OR PROPERLY TORQUE MOUNTING BOLT COULD RESULT IN DAMPER, KEY, ENGINE OR CRANK DAMAGE.

KLM Performance strongly recommends the use of new mounting hardware bolts each time the damper is removed from the crankshaft.

The drivers of performance trucks know how well the Fluidampr 760131 works on their 6.6L Duramax. Only a Fluidampr Harmonic Fluid Damper quiets and smooths out the chatter in diesel engines. These smooth-running engines gain Horsepower and Torque.
