Eagle Nissan RB26 Stroker 4340 Billet Crankshaft

With this Eagle Nissan RB26 stroker crankshaft, you get a precisely machined billet 4340 steel crankshaft designed to increase the displacement of your RB26 engine. This crankshaft features a 3.059-inch stroke, which is longer than the stock stroke, allowing for a larger displacement and potentially more power. The knife-edged counterweights are a notable feature, significantly reducing rotating weight. This reduction helps the engine rev more freely and can improve overall performance.

Constructed from solid billet 4340 steel, this crankshaft is built for strength and durability. The knife-edged counterweights are not just about reducing weight; they are also designed with .125-inch fillet radii. This specific radius is crucial for superior strength at the journal transitions, but it means you'll need to use chamfered or narrowed bearings when installing this crank. The crankshaft also undergoes a nitriding surface treatment and a micropolish finish. Nitriding hardens the surface for improved wear resistance, while the micropolish ensures a smooth finish for optimal bearing performance and longevity.

This crankshaft is intended for builds where performance and reliability under stress are paramount. Given the .125" fillet radius, it's important to ensure you have the correct chamfered or narrowed bearings on hand before beginning installation. Always refer to the manufacturer's installation instructions for specific details regarding bearing selection and assembly procedures to get the most out of this well-built component.
