BimmerSpeed has over 800 Crank Hub jobs completed using none other than the Crank Hub kit from Precision Designed! This 1-piece crank hub design eliminates the possibility of a crank hub from spinning and is designed to have a keyway, with a higher shear strength over dowel pin designs. 

Why do you need this product?

The S55, whether stock or modified, has a possibility of crank hub failure. The OEM crank hub is a 3 piece design, utilizing friction disc to retain engine timing together. The friction disc depends on clamping force to clamp down the pieces of crank hub together. As the engine rotates counter clockwise, over time the crank bolt slowly backs out and loses its clamping force. This will cause engine timing to spin out of position. With enough load, engine timing can significantly be out of timing, causing the intake valves to hit against the engine piston. Severe Crank Hub failure such as this will require replacements of intakes valves, which will be a very expensive repair. We recommend to perform a crank hub service as preventative maintenance. While not all crank hubs fail, preventing it from failing will save you thousands of dollars and give a peace of mind.

Designed to fit:
- 2014+ F8X M3/M4
- 2019+ F87 M2 Competition
- All E/F chassis N55 engine
