Fluidampr's Performance Diesel Series damper for the 2011 and newer Ford 6.7L Power Stroke controls crankshaft torsional vibration with viscous silicone instead of the factory rubber element. Fluidampr lists it as externally balanced for 2011 to present 6.7L applications.
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.
- Damping stays effective as power levels climb, with no tuning or rebuild interval.
- CNC machined, computer balanced high-grade steel with a corrosion resistant black zinc chromate finish.
- Steel construction, 8 in. outside diameter.
- SFI 18.1 certified and made in the USA.
Fitment
- 2011 and newer Ford 6.7L Power Stroke
- External balance
Installation Notes
OEM crank bolt torque is 22 ft-lbs plus an additional 90 degrees; the bolt is torque-to-yield and must be replaced. The 6.7L Power Stroke High Strength Bolt Kit, p/n 300016, is recommended for applications up to 700 hp / 1,250 ft-lbs of torque. In May 2026 Fluidampr released an updated 6.7L Power Stroke damper, p/n 800241, which supersedes p/n 800221.
