Duramax 4340 Forged DS Crank 3.898 Stroke

The CALLIES D333M81-CS Durastar crankshaft is designed for GM Duramax applications and features a 3.898-inch stroke. Its 4340 forged steel construction provides the foundation for a durable crankshaft assembly, while the external-balance design supports the corresponding engine configuration.

This crankshaft uses a 1-piece rear main seal arrangement and is supplied as an individual crankshaft. The Durastar series name and forged-steel construction make this part a focused choice for engine builders seeking a replacement or performance-oriented crankshaft for a compatible GM Duramax setup.

Before ordering, verify engine application requirements, balance configuration, stroke, and rear main seal design against the existing engine components. The CALLIES D333M81-CS combines a 3.898-inch stroke with external balancing and 1-piece seal compatibility in a purpose-built Duramax crankshaft.
