What is the primary benefit of the 4.100-inch stroke?

The 4.100-inch stroke is a common choice for increasing the displacement of LS engines. This larger displacement generally leads to more torque and horsepower potential, especially in naturally aspirated or boosted applications.

What makes this crankshaft suitable for high-performance applications?

It's built from strong 4340 alloy steel and undergoes a multi-step heat treatment and nitriding process for enhanced durability. Features like gun-drilled mains, lightened rod journals, and precisely profiled counterweights contribute to its performance and stability under stress.

What quality assurance steps does Manley perform on these crankshafts?

Each crankshaft is stress relieved and shot peened to improve its internal structure. They are also 100% magnafluxed to ensure there are no hidden flaws before they are shipped out.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine and need a solid foundation, this Manley Pro Series forged crankshaft is a serious contender. It's designed to handle the demands of boosted or naturally aspirated builds where reliability and power are key. The 4.100-inch stroke is a common choice for increasing displacement in LS engines, giving you more torque and horsepower potential.

Manley uses 4340 alloy steel for this crankshaft, a material known for its strength and durability, especially under high stress. They've also incorporated features to optimize performance and longevity. The mains are gun-drilled and the rod journals are lightened, which helps reduce overall weight for better engine response. To ensure it runs smoothly and stays stable at high RPMs, the counterweights are fully profiled for precise balance. A multi-step heat treatment process and nitriding further enhance its strength and resistance to wear.

You'll also find that the journals are micro-polished with large radii. This not only helps reduce friction, which means a little more power can get to the wheels, but it also extends the life of your bearings. Before it leaves Manley, each crankshaft goes through rigorous quality checks, including stress relief, shot peening, and 100% magnafluxing, so you know it meets their high standards. This is a well-built component that forms the core of a powerful engine build.
