SBC 4340 Forged Crank - 4.000 Stroke

The SCAT ENTERPRISES SBC 4340 Forged Crank with 4.000 Stroke is a purpose-built crankshaft designed for small block Chevy engine builds requiring robust strength and precision balance. This forged steel crankshaft delivers the stroke length necessary for increased displacement and torque production in performance and racing applications where internal balance and reliability are non-negotiable.

The 4.000-inch stroke dimension is the critical specification that determines engine displacement when paired with your chosen bore diameter. Forged construction provides superior fatigue resistance compared to cast alternatives, a key advantage under high-RPM and high-boost conditions. The internal balance configuration means this crankshaft is pre-machined for balanced assembly without external counterweights, simplifying installation and allowing cleaner engine bay layouts. The two-piece seal design accommodates modern block configurations while maintaining oil control integrity essential for long-term durability in street and strip applications.

This crankshaft is engineered for engine builders and enthusiasts who demand precision components for small block Chevy platform restorations, performance upgrades, and racing builds. Whether assembling a stroker motor for increased displacement, upgrading from factory cast iron components, or rebuilding after high-performance use, this SCAT forged crank provides the material strength and engineering required to support aggressive builds. Weighing 57.53 pounds, it represents the mass typical of forged small block Chevy cranks designed for dependable service across street, strip, and road course environments.
