About this part

Product Details

Manley Performance is well-known for building strong engine components for demanding applications. This Turbo Tuff Series crankshaft is a prime example, specifically made for Nissan RB26DETT engines that will be pushed hard with high horsepower and high boost. If you're building a serious performance engine, a solid crankshaft is the foundation, and this one is built to handle serious stress.

This crankshaft starts as 4340 billet material, which is then fully machined. The counterweights are knife-edged to help with precise balance and stability, which is crucial when you're spinning an engine at high RPMs under heavy load. To make sure it stands up to the abuse, it goes through a multi-step heat treatment process and nitriding, which significantly increases its strength and how long it will last. Before it leaves the factory, each crank is stress relieved, shot peened, and 100% magnafluxed to ensure it meets Manley's strict quality standards. This level of attention means you're getting a well-built part ready for extreme performance.

When you're building an engine for serious power, starting with a crankshaft like this is key. It's designed to be the backbone of a high-performance RB26DETT, giving you the confidence that your engine can handle the power you're aiming for. Remember to consult the manufacturer's installation instructions for proper balancing and assembly procedures.
