Subaru Crankshafts


The crankshaft is the part of an engine that translates reciprocating linear piston motion into rotation. Our high quality crankshaft subaru can prevent catastrophic failure that occurs due to the stress of tuned engines.

We offer 3 types of Crankshaft;

  • Serviced Crankshafts: These are used units that undergo restoration Serviced Crankshafts are thermal cleaned, crack tested ,checked for run-out, and straightened and machined where necessary.
  • New OEM Forged Crankshaft: As used in most of our Re-Manufactured engines. These Crankshafts are checked for run out and sizing to determine engine bearings prior to fitment.
  • Billet high performance Crankshafts: Whether you are looking to increase engine stroke or strength, for ultimate performance you cannot go past our Billet Cosworth Crankshafts, available for Subaru 2.0lt and 2.5lt Engines.

Original factory crankshafts may not be able to withstand the added stress of a tuned engine, resulting in catastrophic failure. Cosworth billet crankshafts feature full-flowing oil passages whereby each rod journal is lubricated from two main sources. This provides superior lubrication during sustained high rpm use preventing rod bearing failure. Cosworth Subaru crankshafts are manufactured entirely from high grade steel in a light-weight, high strength design with a unique Isotropic Super Finish (ISF®).
