Using only three parts--a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two--these SFI-approved Speedmaster Balancer can control all crankshaft vibration, not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.
