Cosworth Performance Crankshafts

Cosworth Crank

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 failure. Cosworth billet crankshafts are machined from ultra strong EN40B steel, are engineered to endure the harshest conditions and have been tested to withstand over 1,000HP.

Cosworth Racing Crankshafts Feature:
  • Superior lubrication
  • Profiled counterweights
  • High strength
  • Light weight
