The Manley MAN190024NB Pro Series crankshaft is engineered for high-performance Chevrolet LS engine applications. Constructed from durable 4340 non-twist forged steel, this crankshaft is designed to withstand demanding conditions. It features a 4.000-inch stroke, providing a solid foundation for engine builds. This crankshaft undergoes a rigorous multi-step heat treatment process to enhance its strength and resilience. The nitrided surface treatment further increases durability and wear resistance. It is also stress relieved, shot-peened, and 100% magnafluxed to ensure material integrity. The crankshaft comes with a 24-tooth reluctor wheel and is designed for a lightweight profile. This particular model is not balanced. Please ensure proper balancing procedures are followed during engine assembly. The crankshaft is compatible with standard wet sump snout configurations.
