Forged Steel Crankshaft

Our Newly released Forged Steel Crankshaft is a must for the 6.5 liter performance diesel builder.  It can handle the higher horsepower and the higher RPMs required by High Performance 6.5 liter diesels. 

If you are building a workhorse, this is also the one for you.  The Forged Steel Crankshaft is much stronger than the Nodular Iron Crankshaft.
