GM LS 4340 Steel Crank 4.000 Stroke 24X Reluct

The GM LS 4340 Steel Crank 4.000 Stroke 24X Reluctor from EAGLE is designed specifically for serious LS engine builders and high-performance automotive enthusiasts. This crankshaft serves as the rotating foundation for stroker or displacement-increase builds, converting reciprocating piston motion into usable rotational force at the flywheel.

Constructed from 4340 forged steel, this crankshaft offers superior tensile strength and fatigue resistance compared to cast iron alternatives. The 4.000-inch stroke dimension increases displacement per revolution, enhancing torque production, which is particularly beneficial for naturally aspirated builds. The integrated 24X reluctor ring simplifies installation by eliminating the need for external sensor rings.

This crankshaft is ideal for those building high-performance LS engines, whether for street performance or road racing. Its design supports modern LS ECU controllers, ensuring compatibility with advanced engine management systems. When properly balanced and installed with quality components, this crankshaft can provide extended service intervals and reliable performance.
