Product Details
If you're building a high-performance Chevrolet LS engine, a strong and reliable crankshaft is the heart of the operation. This Manley Pro Series crankshaft is forged from 4340 alloy steel, a material known for its excellent strength and durability, making it a solid choice for demanding builds. With a 4.100-inch stroke, it's designed to increase displacement and potential power output for your LS engine.
Manley has put a lot of thought into making this crankshaft perform. The mains are gun-drilled and the rod journals are lightened, which helps reduce overall weight. This isn't just about shedding pounds; a lighter rotating assembly can help the engine rev more freely and respond quicker. The counterweights are carefully profiled to ensure the crankshaft is precisely balanced, which is crucial for smooth operation and longevity, especially at higher RPMs. To further enhance its strength and resistance to wear, the crankshaft goes through a multi-step heat treatment process and nitriding. The journals themselves are large radius and micro-polished, reducing friction where the connecting rods and main bearings ride, which also contributes to better performance and efficiency.
Before any Manley crankshaft leaves the factory, it undergoes rigorous quality checks. This includes stress relief, shot peening to improve fatigue strength, and 100% magnafluxing to detect any potential flaws. These steps ensure that each crankshaft meets Manley's high standards for durability and performance. While this crankshaft is designed for performance, remember that building a complete engine requires careful attention to all components. Ensure you have the correct pistons, connecting rods, bearings, and balancing procedures in place to match the specifications of this crankshaft for optimal results.
