Billet Crankshafts

Increased engine performance often means increased engine speed and load. Original factory crankshafts may not be able to withstand the added stress, resulting in catastrophic engine failure. Additionally, many OE crankshafts rod journals are lubricated from only one main oil feed. Cosworth billet crankshafts featurefull-flowoiling 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®).

Features:

  • Superior lubrication
  • Profiled counterweights
  • High strength
  • Light weight
