    Perfect for engines
    needing quicker RPMs
    These cranks are made of the same aircraft-quality forging as standard 4340 but with profiled counterweights to reduce weight.

    Crankshaft highlights:

  • Straight shot and chamfered oil holes
  • Nitride-hardened for superior wear resistance
  • Lightening holes in all rod throws
  • .125'' radius on all journals
  • Stress-relieved and shot-peened
  • Aero-wing counterweights increase horsepower by reducing windage
  • CNC-machined for absolute tolerances and symmetry for ease of balance
