OEM Forged Salt Bath Nitrated Crankshaft

This crankshaft is available for separate purchase for those of you who need to rebuild your engine starting with a fresh OEM unit. If you have a damaged crank journal where a bearing spun and dug too deep into the metal and you just want a fresh start rather than waiting for a machine shop then this would be a great option.

This is a genuine Subaru crankshaft that is balanced and ready to install on your next engine, and it has been nitride treated which allows the surface to be double-hardened on the Rockwell scale to increase the fatigue life by 25%.
