Product Details
If you're building a high-performance Chevrolet LS engine, a strong, well-balanced crankshaft is the heart of your build. This Manley Performance 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 applications. It features a 4.000-inch stroke, which is a common choice for increasing displacement and power in LS engines.
Manley has put a lot of thought into making this crankshaft perform. The mains are gun-drilled and the rod journals are lightened to reduce overall weight, which helps the engine rev more freely. The counterweights are carefully profiled to ensure the crankshaft is precisely balanced, reducing vibration and improving stability at high RPMs. To further enhance its strength and longevity, this crankshaft goes through a multi-step heat treatment process and is nitrided. The journals themselves are large radius and micro-polished, which cuts down on friction and helps oil flow smoothly, contributing to better overall performance and wear resistance.
Before leaving Manley, each crankshaft is put through rigorous quality checks. This includes stress relief, shot peening to relieve stress concentrations, and 100% magnafluxing to detect any potential flaws. These steps ensure that you're getting a crankshaft that meets Manley's high standards for durability and performance. When building a serious LS engine, starting with a robust and precisely balanced crankshaft like this one sets a strong foundation for your project.
