Performance Crankshafts for BMW, Audi & European Engines

The crankshaft is the central rotating component of your engine — converting piston reciprocating motion into rotational torque. For street builds, a quality crankshaft replacement restores original specifications after wear or damage. For performance builds, an upgraded billet crankshaft can handle the higher loads of increased boost, nitrous, or high-RPM use that would fatigue a factory cast iron crank.

OEM Replacement Cranks

When rebuilding a high-mileage engine, inspect the crank journals for wear before machining. If journals are within spec, a fresh set of bearings may be all that's needed. If journals are damaged or out-of-round beyond re-grind tolerance, a remanufactured or new OEM-spec crank is required.

Performance / Billet Cranks

  • Cast steel (OEM): Factory spec. Handles stock and modestly upgraded power. Fine for street builds up to ~400 hp.
  • Forged steel: Stronger grain structure than cast. The choice for 400–600 hp builds on N54/N55/EA888 platforms.
  • Billet machined: CNC-machined from a single bar of steel. Maximum strength and precision. For extreme builds — 600+ hp, forced induction, or high-RPM naturally aspirated race engines.
