- Scat Forged 4340 Pro Series Lightweight Crankshafts
Nitride hardened to increase strength and longevity, these lightweight crankshafts have the same innovations as Scat's Standard Weight Series yet feature profiled counterweights to reduce weight for more horsepower. They're forged from 4340 steel with lightening holes in all rod journals and straight shot oil holes. Ideal for engines that need a quicker RPM curve.
