Built for serious small block Chrysler performance, this SCAT forged 4340 stroker crankshaft is a strong foundation for a high-output 360-based engine build. With a 4.000 inch stroke and 6.123 inch rod compatibility, it is suited to classic Dodge, Plymouth, Chrysler and Valiant restorations where extra torque, capacity and bottom-end strength are the goal.

The forged 4340 steel construction is a major step up from a standard replacement crank, making it well suited to performance street, strip and race combinations. It features a standard-weight design with lightening holes in the rod throws, helping reduce unnecessary mass while maintaining the strength expected from a serious stroker crankshaft.

Key finishing details include precision grinding, heat treatment, shot peening and micro polishing for improved journal finish and durability. The nitride-hardened surface helps improve wear resistance, while straight-shot, chamfered oil holes assist oil delivery to critical bearing surfaces. Large journal radiuses further support strength in demanding applications.

This crankshaft is intended for internal balance combinations, although final balancing requirements should always be confirmed by your engine machinist as heavy metal may be required depending on the full rotating assembly used. For anyone building a strong Mopar small block with genuine stroker potential, this is a premium crankshaft choice that belongs in a properly machined and professionally assembled engine.
