Voodoo 4.000-Inch Stroke 4340 Forged Steel Crankshaft

The Lunati 70340001LUN Voodoo Crankshaft is designed for GM LS engines, offering a blend of performance features typically found in high-end race components at a more accessible price point. It is constructed from 4340 forged non-twist steel, a material chosen for its exceptional durability and strength, particularly in demanding, high-heat environments. Key specifications include a 4.000-inch stroke and 2.100-inch rod journals, along with a 24-tooth reluctor ring. The crankshaft undergoes a nitride heat-treatment process and features micro-polished journals, both contributing to increased hardness and longevity. To improve engine acceleration and responsiveness, Lunati has incorporated lightening holes in the rod journals, which effectively reduce the crankshaft's inertia weight. Furthermore, the crankshaft's shape and profile are optimized for windage reduction, leading to increased horsepower. This internally balanced crankshaft is designed for use with 6.125-inch or longer connecting rods. Its robust construction and performance-oriented features make it a suitable upgrade for enthusiasts seeking to enhance their GM LS engine's capabilities.
