What material is this crankshaft made from?

This Manley Pro Series crankshaft is manufactured from forged 4340 alloy steel. This material is chosen for its enhanced strength and durability, making it suitable for high-performance applications.

What does the 3.750-inch stroke mean for my engine?

A 3.750-inch stroke, compared to a stock stroke, increases the engine's displacement. This generally leads to more torque and horsepower potential, especially when combined with other performance modifications.

What is the benefit of micro-polished journals?

Micro-polishing the journals reduces surface friction between the crankshaft and bearings. This leads to improved lubrication, reduced wear, and contributes to overall better engine performance and longevity.

About this part

Product Details

If you're building a high-performance Ford 4.6L engine, a strong crankshaft is the foundation of your build. This Manley Pro Series crankshaft is designed to handle the demands of a serious performance engine, offering a 3.750-inch stroke for increased displacement and power potential.

Manufactured from forged 4340 alloy steel, this crankshaft is built for enhanced strength and durability. The rod journals are lightened to help optimize overall engine performance and balance. Manley puts each crankshaft through a multi-step heat treatment process and nitriding, which significantly boosts its strength and ensures it lasts. The journals themselves are micro-polished with large radii, reducing friction and contributing to better performance. To ensure top-notch quality, every crankshaft is stress relieved, shot peened, and 100% magnafluxed to meet Manley's strict standards.

This crankshaft is a key component for anyone looking to get the most out of their Ford 4.6L engine. It's a well-built piece that forms the core of a powerful engine build.
