Cosworth Light Weight Billet Steel Crankshaft 79mm Stroke
Subaru EJ25 Models (inc. 2004+ STI / 2006-2014 WRX)
Features & Product Details
Cosworth is one of the most trusted companies in motorsport due to their rich racing history. They employ some of the world’s best designers and engineers to produce racing products that work in concert together to produce reliable results from full-blown race cars, to street monsters.
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 feature full-flow oiling where by 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®).
