OEM Subaru Forged Nitrided Hardened Crankshaft 2.5L Turbo (12200AA430)



This is the forged nitrided hardened crankshaft found standard in the 2008+ STI. This is a great upgrade for all 2.5L turbo engines and is much stronger than the original earlier crank.  The nitrided hardening process resists scratches and wear from debris and contaminated oil.
