SBM 360 Cast Steel Crank - 4.000 Stroke

The SBM 360 Cast Steel Crank with 4.000 inch stroke is a precision engine component engineered for small block Mopar applications requiring reliable crankshaft performance. This cast steel crankshaft is purpose-built for builders and engine shops seeking a cost-effective foundation for street performance, stock restoration, or moderate boost applications. The 4.000 stroke specification increases engine displacement and low-end torque characteristics compared to smaller stroke alternatives, making it ideal for builders prioritizing drivability and response in naturally aspirated or lightly forced-induction builds.

Manufactured by SCAT Enterprises, a respected OEM and performance crankshaft supplier, the SBM 360 features internal balance design that reduces vibration and stress on bearings and supporting components. The cast steel construction delivers the strength required for durable, long-term operation while maintaining the cost advantage over forged alternatives. Internal balance eliminates the need for external counterweights, simplifying installation and reducing overall engine assembly complexity. The two-piece seal design accommodates both modern and classic Mopar engine configurations, ensuring compatibility with a wide range of small block Mopar blocks and pan combinations without modification.

Engine builders, restoration specialists, and performance enthusiasts working on small block Mopar engines will benefit from this crankshaft's proven durability and balanced engineering. Whether assembling a 360 cubic inch engine for daily driving or competition use, this component integrates seamlessly with standard Mopar engine blocks and ancillary systems. The 59-pound weight and compact dimensions (9.25 x 9 x 26.25 inches) facilitate handling during engine assembly and installation. Proper bearing selection, clearance verification, and alignment are recommended to maximize service life and performance in your Mopar engine build.
