Brian Crower BMW S58B30T0 100.6mm Stroke 4340 Billet Lightweight Crankshaft

What you get with this Brian Crower crankshaft is a fully machined 4340 billet steel crankshaft, ready to be installed in your BMW S58B30T0 engine. This isn't just a stock replacement; it's a significant upgrade designed for builds that demand more from the engine's core. The 100.6mm stroke is a key feature, offering a way to increase displacement and potentially improve torque output.

Brian Crower starts with a solid piece of 4340 billet steel, which is a strong and reliable material for high-performance crankshafts. This billet material is then meticulously machined to precise specifications, ensuring every journal and surface is exactly where it needs to be. The 'lightweight' designation comes from the careful balancing and profiling done during manufacturing, aiming to reduce rotational mass without compromising the crankshaft's integrity. This attention to detail is crucial for engines that will see high RPMs and sustained stress, helping to improve throttle response and overall engine health under demanding conditions.

When you're building an engine to this level, every component matters. This Brian Crower crankshaft is built to handle the increased power and stress that comes with performance tuning. It's a foundational piece for anyone looking to push the limits of their S58 engine, providing a solid and well-built core for their project.
