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. Scat
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.
