Scat forged standard weight crankshafts are designed for street or race engines with substantially increased horsepower. Scat crankshafts are precision-ground, heat-treated, shot-peened, inspected, and micro-polished at Scat for superior tolerance control.

These crankshafts also have a large radius on all journals for improved strength and wear resistance.
