Brian Crower BMW S58B30T0 Stroker Kit - 96mm Billet LW Crank/ProH625+ Rods/Pistons

If you're looking to significantly increase the displacement and power potential of your BMW S58 engine, a stroker kit is the way to go. This Brian Crower kit is built around a 96mm billet crankshaft, which is a notable increase over the stock stroke. This larger stroke, combined with the included ProH625+ connecting rods and custom pistons, allows for a substantial bump in engine displacement, leading to improved torque and horsepower across the entire RPM range. It’s a comprehensive package designed to give your S58 a serious performance edge.

Brian Crower is known for using strong, well-built components, and this kit is no exception. The 96mm crankshaft is forged from a solid billet for maximum strength and durability, capable of handling the increased stresses of a larger displacement engine. The ProH625+ connecting rods are made from high-strength alloy and feature robust hardware, ensuring they can withstand the higher cylinder pressures and forces generated. The kit also includes custom-designed pistons, tailored to work with the new stroke and rod length, optimizing compression and combustion. This combination of components is engineered to work together seamlessly, making it a popular choice for those building a high-performance S58 engine.

When undertaking a stroker build like this, it's important to have a clear plan for supporting modifications. You'll want to ensure your fuel system, tuning, and cooling system are up to the task of handling the increased power output. This kit is a significant upgrade, and proper installation and supporting modifications are key to unlocking its full potential and ensuring long-term reliability. Please note that this kit is not CARB approved and cannot be shipped to California.
