Scat 4340 Forged Pro Comp Lightweight Crankshafts

Product images may differ from actual product appearance.

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
