What is the primary benefit of a 95.6mm stroke crankshaft?

A longer stroke, like the 95.6mm on this crankshaft, increases the engine's displacement. This generally leads to more torque and power output, especially in the mid-range RPMs.

Why is 4340 billet steel used for this crankshaft?

4340 billet steel is chosen for its exceptional strength and resistance to fatigue under high loads. Being billet means it's machined from a solid block of steel, making it a very robust and reliable component for performance engines.

What else might be needed when installing this crankshaft?

When installing a performance crankshaft, it's crucial to ensure proper bearing clearances, oiling, and potentially balancing of the entire rotating assembly. Always consult the manufacturer's installation guide for specific requirements.

Product Details

This is a Brian Crower 4340 billet crankshaft designed for BMW M50 and M52 engines. It features a 95.6mm stroke, which is a common upgrade for increasing displacement and improving torque in these inline-six BMW engines. If you're building a performance engine or rebuilding your top end, a strong crankshaft is the foundation for reliable power.

Brian Crower uses 4340 billet steel for this crankshaft, a material known for its exceptional strength and durability under high stress. This billet construction means the crankshaft is forged from a solid piece of steel, making it significantly stronger than cast or even forged crankshafts that aren't billet. The 95.6mm stroke is a popular choice for M50/M52 builds, offering a good balance between increased displacement and maintaining reasonable rod angle for engine longevity. This crankshaft is precision-machined and balanced to ensure smooth operation and reduce vibrations, which is critical for high-revving BMW engines.

When installing a performance crankshaft like this, it's essential to ensure all supporting components are up to the task. This includes proper bearing clearances, oiling, and balancing of the rotating assembly. Always refer to the manufacturer's installation instructions for detailed specifications and recommended procedures to ensure a successful build.
