Sledgehammer®

Sledgehammer® crankshafts are the perfect foundation for a budget minded engine build. Forged from 4340 non-twist steel, this line of durable Lunati cranks feature a special Nitride heat treatment, sonic cleaning, and micro-polishing for added insurance in performance street engines and mild race applications. Each crankshaft incorporates many premium features normally found on high end race crankshafts, such as drilled lightening holes in the pin arms to reduce reciprocating mass.
