What is the primary benefit of using a billet crankshaft like this one?

A billet crankshaft, like this Manley Turbo Tuff Series unit, is machined from a solid block of high-strength steel. This construction method results in a much stronger and more durable component compared to a forged or cast crankshaft, making it ideal for high horsepower and high boost applications where extreme stresses are present.

What does the nitriding process do for the crankshaft?

Nitriding is a surface hardening heat treatment that infuses nitrogen into the outer layer of the steel. This process significantly increases the crankshaft's surface hardness and wear resistance, which helps it withstand the high pressures and friction encountered in demanding performance engines.

Does this crankshaft come with bearings or other installation hardware?

This listing is for the Manley Turbo Tuff Series billet crankshaft itself. Bearings, seals, and other necessary installation hardware are typically sold separately and should be sourced to meet the specific requirements of your engine build.

About this part

Product Details

If you're building a high-horsepower Nissan RB26DETT engine for serious boosted applications, a strong crankshaft is the foundation of your build. This Manley Performance Turbo Tuff Series billet crankshaft is designed to handle the extreme demands of turbocharged performance, giving you the reliability you need when pushing your engine to its limits.

This crankshaft starts as a solid piece of 4340 Turbo-Tuff billet material, which is then fully machined to Manley's exacting standards. The counterweights are knife-edged to reduce windage and ensure precise balance and stability, crucial for high RPM operation. To further enhance its strength and longevity, the crankshaft goes through a multi-step heat treatment process and is nitrided. This surface hardening treatment significantly increases wear resistance and fatigue strength, making it well-suited for high boost pressures and increased cylinder pressures.

Manley doesn't stop there. Each crankshaft is stress relieved, shot peened to relieve internal stresses, and 100% magnafluxed to detect any potential flaws. This rigorous quality assurance process ensures that you're getting a well-built component ready for your demanding build. While this crankshaft is designed for performance, it's important to note that it is intended for off-road use and may not be legal for sale or use in California due to Proposition 65 regulations.
