Overview  
Genuine OEM Parts Part #: 12200AA430

This is the Nitride treated crankshaft out of the 2010 Subaru WRX STi EJ257.


Nitride treatment hardens the surface of the crank, which prevents scoring caused by a piece metal getting stuck between the bearing and the crank.

By increasing the hardness of the crankshaft surface, any material which gets caught between the new surfaces is simply ground down and filtered out through the oil, potentially preventing bearing failure.

This is a brand new part, straight from Subaru!

The Subaru Part # for this Nitride Treated Crank is 12200AA430

Actual product may vary from picture.

Warranty Disclaimer: Subaru of America will only warranty parts installed on a car that has a matching VIN to that part.

Warranty Disclaimer: Subaru of America will only warranty parts installed by a CERTIFIED Subaru Dealership. The part being installed must also match the vehicle VIN. IE If you install an STi block in a WRX at your friends shop, do not expect a warranty claim to come through if it explodes! Please use your best judgement.
