GM Performance Crankshafts

 GM Performance Parts crankshafts are designed for use in various applications including your LS-6 and LS-7 big-block V8s. Constructed of forged steel, they're nitride treated to increase hardness and fatigue strength. The main bearing journals are cross-drilled to provide a constant supply of oil to the rod bearings. Many other crankshaft part numbers are available.

Contact www.southeastperformance.com for your application and pricing.
