I will use them again if needed no doubt and I am telling everyone I know that if they need a crankshaft there is no need to look anywhere else.

Before ordering, check the identification number on your existing crankshaft and confirm its material and rear main seal configuration. Year, model, and engine size alone may not distinguish the cast and forged versions.

If your application requires cast iron, review part 18041 and confirm compatibility. If selecting forged steel as an upgrade, have your engine builder verify the replacement and rotating assembly balance requirements.

Unsure which version you need? Contact us with your vehicle information, crankshaft identification number, and clear photos of the original crankshaft.
