The connecting rod is the vital link between the piston and power. When engine output is increased, the demands placed on the connecting rod increase as well. To ensure engine reliability in all conditions, original connecting rods should be replaced with heavy duty specification parts. Cosworth Forged Connecting Rods are manufactured from high strength 4340 (EN24) steel and machined to precise tolerances.

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, factory Subaru crankshaft rod journals are lubricated from only one main oil feed. Cosworth billet crankshafts feature full-flow oiling 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 in house from EN40B steel in a light weight-high strength design with a unique Isotropic Superfinish.
