This Fluidampr Performance Diesel Series damper is listed by the manufacturer for 2010.5-2016 GM 6.6L Duramax LML and LGH engines. The viscous design protects the crankshaft, main bearings and timing gear across the entire RPM range.

Key Features

  • Viscous design uses a free-rotating inertia ring sealed inside a laser-welded steel housing, shearing through silicone to convert crankshaft torsional vibration into heat.
  • Includes the hardened crankshaft washer with clearance for the GM 3.200 in. bolt circle.
  • 8-3/8 in. outside diameter, 25 lbs total weight.
  • Never requires tuning, rebuilding or maintenance, unlike a rubber elastomer balancer.
  • SFI 18.1 certified and made in the USA.

Fitment

  • 2010.5-2016 GM / Chevy 6.6L Duramax LML and LGH

Installation Notes
