Polished & Balanced Crankshaft:

Polishing a Crankshaft removes small imperfections, tiny surface scratches and cracks to help reduce the amount of oil that sticks to it. Offering you longer, more reliable bearing life.
Balancing the Crankshaft is vital to any stock or performance engine to decrease overall torsional vibration in the entire rotating assembly. This process allows the engine to run smoother and increases bearing life.
