SBC F-43 Forged Crank – 4.000 Stroke 4-400-4000-6000-21LW

Description

A forged crankshaft is the backbone of any high-revving small block Chevy engine build—it’s where durability meets displacement. The SBC F-43 delivers the 4.000-inch stroke you need for increased cubic inches and torque, while its forged steel construction handles the demanding loads of forced induction, nitrous, or high-RPM applications. Whether you’re building a street performance engine or prepping for the track, this internally balanced crank eliminates the guesswork and gets you to the dyno faster.
