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.

This is the cast iron crankshaft for listed 6.0L / 366ci and 7.0L / 427ci applications with a one-piece rear main seal. Listed crankshaft identification number: 10114187.

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 forged steel, review part 18041S and confirm compatibility. If changing crankshaft material or rebuilding a modified engine, 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.
