SBC 4340 Forged Crank - 3.480 Stroke

The EAGLE SBC 4340 Forged Crank with 3.480 stroke is a premium component designed for serious small-block Chevrolet engine builders who require exceptional durability and performance. This crankshaft is particularly suited for high-RPM racing applications, street performance builds, and forced-induction setups where reliability is crucial.

Constructed from 4340 chromoly steel, this forged crankshaft offers superior strength-to-weight characteristics compared to traditional cast components. Its 3.480-inch stroke enhances engine displacement and low-end torque when paired with the appropriate piston and rod combinations. EAGLE's precision manufacturing ensures tight tolerances on all journals and throws, which are vital for proper bearing clearance and minimal vibration.

This crankshaft is ideal for builders focusing on high-performance applications, particularly those targeting 400+ cubic inch displacement in small-block Chevy platforms. It is compatible with both LS and traditional small-block setups that require a stroker configuration, making it a versatile choice for performance enthusiasts.
