Brian Crower Nissan VQ37HR Stroker Kit - 92mm Stroke Billet Crank Custom Rods (5.886 inch) Custom

This Brian Crower stroker kit for the Nissan VQ37HR engine includes a 92mm billet crankshaft, custom connecting rods with a 5.886-inch length, and a set of main and rod bearings. This kit is designed to increase the engine's displacement, leading to improved torque and horsepower when properly tuned. It's a popular choice for builders looking to extract more performance from their VQ37HR-powered vehicles, such as the Nissan 370Z, Infiniti G37, and Infiniti Q50.

The heart of this kit is the 92mm billet crankshaft, machined from solid steel for exceptional strength and durability. This allows for a longer stroke compared to the factory crank, which directly translates to more cubic inches and greater potential for power. The custom-forged connecting rods are built to handle the increased stress of a stroker engine, featuring a 5.886-inch length that's optimized for the VQ37HR platform and the new crankshaft. High-performance main and rod bearings are also included to ensure smooth operation and longevity for the increased loads.

Installing a stroker kit is a significant engine modification that requires careful attention to detail and often involves balancing the rotating assembly. It's recommended to consult with a professional engine builder or refer to detailed service manuals for proper installation procedures. This kit is intended for enthusiasts aiming to build a high-performance engine and should be paired with appropriate supporting modifications and tuning to realize its full potential.
