Forged Chromoly Crankshafts are machined from a 4140 Chromoly forging. Chromoly steel is one of the strongest metals that can be used for the manufacture of crankshafts. Progressive dies are used in the forging process to assure a grain flow that follows the shape of the finished crankshaft.
The special design of the counterweights help reduce oil foaming during high RPM while smoothing out your engines entire power range. The integral counterweights flatten out high-speed harmonics and dampen engine vibration. Check out the features list below to see why Forged Chromoly Crankshafts are the natural choice for high performance engines.
Forged into the shape of a VW crank and then CNC machined, ground and micro polished, every CB Forged Chromoly Crankshaft is shot peened, balanced and equipped with 8 hardened dowels. The bearing journals are standard, because it's brand new and it's stronger than a previously owned welded crank.
