Description

Speedmaster forged standard weight crankshafts are designed for street or race engines with substantially increased horsepower. Speedmaster crankshafts are precision-ground, heat-treated, shot-peened, inspected, and micro-polished for superior tolerance control. Speedmaster crankshafts are also nitride-hardened for superior wear resistance, have straight-shot and chamfered oil holes, and feature lightening holes in all rod throws. These crankshafts also have a large radius on all journals for improved strength and wear resistance.
