Product Details
When you're building a high-performance Chevrolet LT1 engine, the crankshaft is the heart of it all. What you get in this package is a Manley Performance Pro Series crankshaft, forged from 4340 alloy steel with a 3.622-inch stroke. This isn't just a replacement part; it's a foundational piece for serious engine builds, designed to handle increased power and stress.
Manley has put a lot of thought into making this crankshaft perform. It features a lightweight, non-twist forging process, which helps reduce overall engine weight and improve responsiveness. To further optimize performance, the mains are gun-drilled and the rod journals are lightened, all while maintaining precise balance with fully profiled counterweights. The strength and longevity are significantly improved through a multi-step heat treatment process and nitriding. Plus, the large radius journals are micro-polished to minimize friction, allowing for smoother operation and better power delivery.
Before this crankshaft leaves Manley, it goes through a rigorous quality assurance process. This includes stress relief, shot peening for surface durability, and 100% magnafluxing to ensure there are no hidden flaws. This attention to detail means you're getting a well-built component ready for your demanding engine project. Because this is a critical engine component, always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
