Product Details
This is the Manley Performance Pro Series crankshaft, built for Chevrolet Big Block engines with a 4.000-inch stroke. If you're rebuilding the heart of your engine, a solid crankshaft is absolutely critical for reliable power and longevity. Manley uses a 4340 alloy steel non-twist forging for this piece, which means it's built to handle the stresses of a high-performance application while keeping weight down.
To make sure this crankshaft stands up to the demands you'll put on it, Manley puts it through a multi-step heat treatment process and nitriding. This significantly boosts its strength and resistance to wear over time. The journals are also micro-polished with large radii, which helps reduce friction inside your engine and contributes to overall performance. Every single crankshaft is also stress relieved, shot peened, and 100% magnafluxed to ensure there are no hidden flaws before it ever leaves the factory. This rigorous quality assurance means you can install it with confidence.
When you're building a serious engine, starting with a well-made crankshaft like this Manley Pro Series unit is a smart move. It's designed to be a durable foundation for your build, ready to accept other performance components and deliver power reliably.
