The Pittsburgh Power Mercury Filled Balancer reduces rotational vibration in crankshafts, rods, pistons, flywheels, and clutches. The mercury filled tube corrects imbalance in the rotating mass, creating a smoother running engine and increasing engine performance, durability, and reduces cab vibrations and noise. Unlike ball bearing balancers, mercury never wears out and is much quieter. This product is included with a Lifetime Factory Warranty.
Please do not confuse this part with a torsional vibration damper. Dampers are required while the balancer is optional equipment. The damper absorbs vibrations while the balancer corrects imbalances in the rotating mass.
*Note for CAT C-12/C13 owners. This damper may not be a direct bolt on for you if you have the 8 extra bolts on the damper outside of the center 6 bolts. Take a look at your damper before buying.
