Product Details
If you're building a high-performance Chevy LS engine, a strong and reliable crankshaft is the heart of the operation. This Manley Performance Pro Series crankshaft is forged from 4340 alloy steel, a well-known material for its toughness and ability to handle significant stress. It's designed to be a lightweight option, which helps improve engine response and overall performance, especially in racing or extreme street applications. The gun-drilled mains and lightened rod journals are key features contributing to this weight reduction without compromising the part's integrity.
Manley puts this crankshaft through a multi-step heat treatment and nitriding process, which significantly boosts its strength and resistance to wear, ensuring it can handle the demands of a powerful engine over time. The journals are also given a large radius and micro-polished finish. This not only helps reduce friction, meaning more of your engine's power makes it to the wheels, but it also contributes to smoother operation and longer bearing life. Each crankshaft is rigorously inspected, including stress relief, shot peening, and 100% magnafluxing, to meet Manley's strict quality standards. This ensures you're getting a part that's ready for serious work.
This crankshaft is a critical component for anyone looking to build a robust LS engine. While it's designed for performance, its well-built nature and thorough quality checks make it a solid choice for demanding applications. Always refer to the manufacturer's installation instructions for proper balancing and assembly procedures to get the most out of this high-performance component.
