Fluidampr recommends replacing the diamond impregnated friction washer in the Fluidampr Cummins Full Power Kit and the Fluidampr High Strength Bolt & Friction Washer Kit each time the damper is removed. This practice ensures a secure mating surface between the damper and the crankshaft. Available in single or three pack.
