What is the purpose of the 58-tooth reluctor wheel?

The 58-tooth reluctor wheel is a critical component for the engine's computer (ECU) to accurately track crankshaft position and speed. This allows for precise ignition timing and fuel injection, which is essential for modern engine management systems, especially in high-performance applications.

What does micro-polishing the journals do?

Micro-polishing the crankshaft journals reduces surface friction. This leads to less parasitic drag within the engine, improved oil flow and lubrication, and ultimately contributes to better overall performance and longevity of the crankshaft and bearings.

What is the benefit of using billet 4340 steel for a crankshaft?

Using billet 4340 steel provides a very strong and dense foundation for the crankshaft. It's less prone to internal flaws than cast materials and can withstand higher stresses, making it ideal for high-performance engines that experience significant cylinder pressures and RPMs.

About this part

Product Details

When you're building a high-performance engine from the ground up, the crankshaft is the heart of it all. This Manley Performance Pro Series crankshaft is forged from 4340 alloy steel, specifically a "Turbo-Tuff Billet" material, chosen for its exceptional strength and durability under demanding conditions. With a 4.000-inch stroke and a 58-tooth reluctor wheel, it's designed for builds where precise engine management and significant power output are key goals.

Manley puts these crankshafts through a multi-step heat treatment and nitriding process to further enhance their strength and ensure they hold up over time. The mains are gun drilled and the rod journals are lightened, contributing to a lower overall weight which helps optimize engine performance and responsiveness. Every journal is micro-polished with large radii, reducing friction and improving the flow of oil for better lubrication. This attention to detail means less parasitic drag and more power reaching the wheels.

Before leaving the factory, each crankshaft is stress relieved, shot peened for fatigue resistance, and 100% magnafluxed to catch any potential imperfections. This rigorous quality assurance process ensures you're getting a solid, reliable component ready for your custom engine build. The counterweights are fully profiled for precise balancing, which is critical for smooth operation and longevity at higher RPMs.
