We offer 3 types of Crankshaft;
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®).
