Our factory stock turbo cranks are cast & are weak-thats why the factory rolled the filets.Why pay $300-400 for a used cast that you still have to take to the machine shop & have inspected, magna-fluxed, polished, or turned when you can have brand new forged steel one!!
One nice thing about steel cranks (versus cast iron) - they don't flex as much. Therefore, your caps and mains don't take as much stress, because they don't have to try as hard to keep the crankshaft straight.
4340 FORGED STEEL CRANKSHAFTS
Forged 4340 steel crankshafts have been tested and proven to excel in engines producing 1,000 horsepower and 10,000 RPM. The premium 4340 aircraft quality steel with vacuum degassed forging process creates a clean and pure crankshaft. The state-of-the-art CNC machine centers provide superior tolerance.
4340 crankshafts incorporate these features:
- Computer designed counterweight to reduce main bearing loads.
- CNC machined to provide superior tolerance and journals micro polished to 5 RMS.
- Generous 0.125" journal radii to disperse stress under high loads.
- Each crankshaft has been visually inspected, X-rayed, magnafluxed, and ultrasonic tested to ensure perfection.
- Journal surfaces are treated with plasma gas nitrite to HRC60 hardness for superior wear resistance.
