Fluidampr GM/Chevy 6.6L L8T Crankshaft Damper

Jan 25, 2024

Fluidampr's GM/Chevy 6.6L L8T performance crankshaft damper (part# 760151) was originally developed for high-torque towing capacity in GM's heavy-duty truck line. However, the robustness of the cast-iron block with nodular iron main caps and a forged steel crankshaft also promises great potential for engine swaps and crate engine programs.

Upgrading to a Fluidampr performance damper ensures long-term durability and optimum power by controlling crankshaft torsional vibration. In addition, a custom mandrel to power racing parts, such as a dry-sump, can easily be installed by using the damper's pre-drilled and tapped 3.2" bolt circle pattern.
