Description

If you’re building a high-revving Small Block Chevy engine or upgrading from a cast-iron unit, a forged crankshaft is non-negotiable. The Manley SBC 4340 Forged Crank delivers the strength and reliability needed to handle increased boost, nitrous, or sustained high-RPM operation without risk of catastrophic failure. This is the foundation every serious SBC build depends on.

Manley’s 4340 forged steel construction resists the stress concentrations that cause cast cranks to fracture under extreme loads. The internally balanced design simplifies your rotating assembly and reduces parasitic losses, while the two-piece rear seal accommodates both vintage and modern engine configurations.
