SBC 4340 Forged Crank - 4.000 Stroke

The SCAT ENTERPRISES SBC 4340 Forged Crank with 4.000 Stroke is essential for serious small-block Chevrolet builds that demand reliability under high RPM and boost conditions. Engine builders and performance enthusiasts will appreciate its durability, transforming a stock short block into a platform capable of supporting aggressive cam profiles, nitrous oxide systems, and forced induction setups.

Forged from 4340 chromoly steel, this crankshaft offers superior fatigue resistance and impact strength compared to cast alternatives, which is critical when cylinder pressures exceed stock parameters. The 4.000-inch stroke increases displacement and low-end torque production, allowing for a lower powerband than typical 3.480-inch stroker cranks while maintaining compatibility with standard SBC bore spacing.

This crankshaft is ideal for building street monsters, weekend warriors, or competition engines, providing the strength and geometry necessary for sustained power delivery. SCAT's precision machining ensures strict tolerances on journal diameters, fillet radii, and surface finishes, preventing premature wear and catastrophic failure under sustained boost or nitrous exposure.
