Brian Crower BMW M50B25 Crankshaft 4340 Billet 95.6mm Stroke

Brian Crower is well-known for making serious engine components for performance builds. This 4340 billet crankshaft is a prime example, designed specifically for the BMW M50B25 engine. If you're building a high-performance M50 engine, a strong crankshaft is the foundation, and this piece is built to handle significant power.

This crankshaft features a 95.6mm stroke, which is longer than the stock stroke. A longer stroke generally means more displacement and potential for increased torque and horsepower, especially when paired with other performance modifications. It's forged from 4340 billet steel, a material known for its exceptional strength and durability under high stress. This means it can withstand the increased cylinder pressures and rotational forces common in modified engines. The billet construction means the entire crankshaft is machined from a solid block of steel, resulting in a more uniform grain structure and greater overall integrity compared to a forged crankshaft made from multiple pieces.

When you're pushing an engine hard, the crankshaft is one of the most critical components. Choosing a well-built, billet steel crankshaft like this Brian Crower unit is a smart move for anyone serious about building a reliable, high-output BMW M50 engine. It's designed to be a direct replacement for the stock crankshaft, simplifying installation into your engine build.
