Description
The Manley Subaru EJ25 crankshaft is manufactured from premium multi-heat treated lightweight 4340 billet steel and nitrided for additional strength. The crank features fully profiled knife edged counterweights and is stress relieved as well as shot peened. Each crank is balanced and 100% magnafluxed to assure quality. Manley’s Turbo Tuff 79mm stroke 2.5L crankshaft weighs in at 18 lbs. partially due to its gun drilled crank pin and counterweights. The crank is designed to be a direct replacement for the OEM 2.5l crank.
