Brian Crower Polaris XP Turbo (16-up) Stroker Kit 75mm w/BC Pro625+ Rods

Starting with a 75mm stroke crankshaft, this stroker kit from Brian Crower is built to increase the displacement of your Polaris XP Turbo engine. A longer stroke means the piston travels further in the cylinder with each rotation, which directly translates to more air and fuel being drawn in and compressed. This fundamental change in engine geometry is key to unlocking significant power gains, especially when paired with other performance modifications. The kit is designed for 2016 and newer Polaris XP Turbo models, offering a direct path to a more potent powerplant.

At the heart of this kit are the BC Pro625+ connecting rods. These are not your average rods; they are forged from high-strength 4340 aircraft-quality steel, a material chosen for its exceptional durability and ability to withstand the immense forces generated in a high-performance engine. They feature a multi-stage heat-treat process that further enhances their strength and fatigue resistance. The rods are paired with high-performance rod bolts, specifically ARP 625+ fasteners, which are known for their superior tensile strength and reliability under extreme stress. This robust rod and bolt combination is crucial for ensuring the longevity of your engine when pushing performance limits.

Brian Crower has a reputation for producing well-built internal engine components, and this stroker kit is no exception. The crankshaft itself is typically forged and precision-balanced to ensure smooth operation at high RPMs. While this kit is designed to be a comprehensive solution for increasing displacement, it's important to note that it is not CARB approved and cannot be shipped to California. For optimal performance and reliability, it's always recommended to consult with a professional engine builder to ensure all components are installed correctly and that the engine's tuning is adjusted to take full advantage of the stroker kit's capabilities.
