| GM Performance Parts 14088526 Crankshaft, Cast-iron
A crankshaft is that massive piece of convoluted steel that holds the whole engine together. An engine is essentially a pump, and without a strong crankshaft, the pump won’t work. GM Performance Parts puts the same top-quality engineering and manufacturing processes into its crankshafts as it does with all its parts. These crankshafts are the same ones used in GM Performance Parts crate engines. The crankshafts are available in cast-iron and forged steel. Forged crankshafts should be used for higher-horsepower applications.
Nodular cast-iron with 3.480" stroke and 2.100" diameter rod journals
1-piece rear main seal crankshaft for 300- and 330-horsepower engines
NOTE: This crank does not have a pilot bearing.
