Brian Crower Nissan RB26/RB25 Stroker Kit - 79mm Stroke Billet Crank Severe-Duty Rods (4.783 inch)

If you're looking to significantly increase the displacement and power potential of your Nissan RB26 or RB25 engine, a stroker kit is the way to go. This kit from Brian Crower is built for serious performance builds, taking your engine beyond its stock limits. By increasing the crankshaft stroke from the factory 73.7mm to 79mm, you're effectively making the engine a larger displacement, which directly translates to more torque and horsepower potential, especially in the mid-range and top end.

At the heart of this kit is a 79mm billet crankshaft. Billet construction means it's machined from a solid block of steel, making it incredibly strong and resistant to the stresses of high-performance engines. This is crucial for handling the increased forces generated by the longer stroke and potentially higher cylinder pressures. Complementing the crank are Brian Crower's severe-duty connecting rods. These rods are also well-built for demanding applications and feature a 4.783-inch length, which is a common and effective length for RB stroker builds. The combination of a strong billet crank and robust rods is essential for reliability when pushing an engine hard.

This kit is designed to be a comprehensive solution for your engine build. While it's a significant upgrade, remember that modifying engine displacement often requires other supporting modifications to take full advantage of the increased capacity. This includes tuning, fuel system upgrades, and potentially head work. Please note that this kit is not CARB approved and cannot be shipped to California. Always consult with a professional engine builder to ensure all components are compatible with your specific build goals and that installation is performed correctly.
