About this part

Product Details

If you're building a high-performance Ford 4.6L engine, starting with a solid crankshaft is key. This Manley Pro Series crankshaft is built for serious builds, offering a 3.543-inch stroke to help you achieve the displacement and power you're aiming for. It's designed to handle the demands of performance applications, providing a strong foundation for your engine.

Manley crafts this crankshaft from forged 4340 alloy steel, a material known for its strength and durability, especially under high stress. They've also incorporated lightweight rod journals and fully profiled counterweights. This design helps with precise balancing and stability, which is crucial for smooth engine operation at higher RPMs. The journals themselves are micro-polished with large radii, reducing friction and contributing to overall engine efficiency and longevity.

To further enhance its toughness, this crankshaft goes through a multi-step heat treatment process and nitriding, which significantly boosts its strength and resistance to wear. Before it leaves Manley, each crankshaft is stress relieved, shot peened, and 100% magnafluxed. This rigorous quality assurance process ensures that every crankshaft meets strict standards for reliability and performance. If you're looking for a well-built crankshaft for your performance Ford 4.6L build, this Pro Series option is a solid choice.
