Forged Crankshafts

Your factory 496 cast crankshaft is built to handle the stock output of the GM 8.1L Vortec 8100 engine. In performance applications, the crankshaft can become the "weak link" of your engine which can lead to catastrophic engine failure. Our forged crankshafts are a must for any high horsepower or supercharged application. Please note - the 4.75" crankshaft requires clearance machining to fit in stock Vortec 8100 blocks. Please consult your preferred machine shop about clearancing your engine block.
