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

The 58-tooth reluctor wheel is a critical component for the engine control module (ECM) to accurately track crankshaft position and speed. This specific tooth count is standard on many Chevrolet LS engines and is necessary for proper engine operation and tuning.

What does '4340 alloy steel' mean for this crankshaft?

4340 alloy steel is a high-strength steel known for its excellent durability and resistance to fatigue. Using this material means the crankshaft is well-suited for high-performance applications where it will experience significant stress and heat.

What is the benefit of micro-polished journals?

Micro-polishing the journals creates an extremely smooth surface finish. This smoothness reduces friction between the crankshaft and connecting rod bearings, which can lead to improved engine efficiency and longevity.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, starting with a strong foundation is key. This Manley Performance Pro Series crankshaft is forged from 4340 alloy steel, a material known for its excellent strength and durability, making it a solid choice for demanding builds. It features a 4.100-inch stroke and a 58-tooth reluctor wheel, designed to work with the specific engine management systems found in many LS variants.

Manley puts these crankshafts through a multi-step heat treatment process and nitriding to further enhance their strength and ensure they hold up over time. The journals are micro-polished with large radii, which helps reduce friction and improve overall engine performance. To optimize the rotating assembly's weight and balance, the mains are gun-drilled and the rod journals are lightened, with fully profiled counterweights for precise balancing. Every crankshaft is also stress relieved, shot peened, and 100% magnafluxed to meet Manley's strict quality standards, giving you confidence in its integrity.

This crankshaft is a significant component for anyone looking to push the limits of their LS engine. It's designed for serious builds where reliability and performance are paramount. Ensure you have the correct supporting components, such as pistons, connecting rods, and bearings, that are compatible with its 4.100-inch stroke and journal sizes for a successful engine assembly.
