Scat Forged 4340 Lightweight Crankshafts

Product images may differ from actual product appearance.

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.

Features
  • Forged 4340 construction
  • Profiled aero-wing counterweights
  • Straight shot & chamfered oil holes
  • Nitride hardened for superior wear resistance
  • Lightening holes in all rod throws
  • Large radius on all journals
  • CNC machined for absolute tolerances and symmetry for ease of balance and for reduced rotating weight
