BBC 4140 Forged Crank 4.000 Stroke Int Bal

The BBC 4140 Forged Crank 4.000 Stroke Int Bal by EAGLE is an essential component for serious big-block Chevrolet engine builds. It is particularly suited for enthusiasts and professional builders focused on high-performance street, strip, or racing applications. This crankshaft is designed to enhance the performance of engines that utilize a 4.000-inch stroke.

Manufactured from 4140 chromoly steel, this forged crankshaft provides superior tensile strength and fatigue resistance compared to cast alternatives. The 4.000-inch stroke increases displacement and torque production, making it ideal for builds focused on maximizing torque. While the internal balancing reduces the need for external balancing in many cases, installers should still verify compatibility based on their specific engine setup.

This crankshaft is purpose-built for BBC applications and pairs seamlessly with connecting rods, pistons, and cylinder blocks designed around the 4.000-inch stroke specification. Builders can expect durability and precision, making it a reliable choice for competition-grade powerplants. Proper journal clearances and bearing compatibility should always be confirmed during installation.
