Fluidampr 760131 6.6L Duramax 01-23 Fluidampr Harmonic Damper

Fluidampr Viscous Internal Balance Duramax Diesel Crankshaft Damper 

NOTE: The Fluidampr 760131 Harmonic Balancer is a direct bolt-on replacement high-performance damper designed solely for use on the 6.6L Duramax diesel engines running a balanced internal rotating assembly!  Only for applications that have been converted from OEM external balance to internal balance assembly. The installation of this damper on an externally balanced crankshaft assembly can lead to engine failure!

This high-performance viscous damper is currently available. 

High-Performance Fluidampr 760131 6.6L Duramax Fluidampr Replacement Viscous Harmonic Fluid Damper. This Fluidampr Harmonic Balancer is only approved for installation on an internally/neutral Balanced Rotating Assembly. An internally/neutral balanced rotating assembly comes as a pre-balanced from the crankshaft manufacturer. This Fluidampr Viscous Internal Balance Duramax Diesel Crankshaft Damper can be installed without taking the parts to the machine shop, provided you have replaced your OEM externally balanced crankshaft with an aftermarket internally or neutrally balanced crankshaft.  

Fluidampr 760131 Internally Balanced Damper is Approved For These Duramax Applications with an aftermarket internally or neutrally balanced crankshaft:

Fluidampr has developed two high performance parts to ensure this damper stays attached to your engine crankshaft. A diamond-impregnated friction washer creates 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 that helps ensure your viscous performance diesel damper will stay in place.

WARNING: THE FAILURE TO USE OR THE PROPER TORQUE MOUNTING AND TORQUE SPECIFICATION COULD RESULT IN DAMPER, KEY, ENGINE, OR CRANK DAMAGE.

KLM Performance strongly recommends using 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. 

NOTE: KLM Performance strongly recommends that you read all of the descriptive text regarding the use and or application of this Fluidampr Harmonic Balancer on a Duramax Diesel Engine.
