Covering the 2006-2010 GM 6.6L Duramax LBZ and LMM, this externally balanced Fluidampr damper controls crankshaft torsional vibration with viscous silicone rather than a tuned rubber ring. Cracked or bulging rubber on a factory balancer is the usual reason owners make the swap.

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 with 16.8 lbs rotating weight.
  • CNC machined, computer balanced high-grade steel with a corrosion resistant black zinc chromate finish.
  • SFI 18.1 certified and made in the USA.

Fitment

  • 2006-2010 GM / Chevy 6.6L Duramax LBZ and LMM
  • External balance

Installation Notes

OEM crank bolt torque is 74 ft-lbs plus an additional 105 degrees, using a new torque-to-yield bolt. Fluidampr recommends High Strength Bolt Kit p/n 300010 for builds around 500 hp and above.
