Why Upgrade the Crank Hub in BMW F8x M2, M3, and M4?

Owners of BMW F8x M2, M3, and M4 with the S55 engine may encounter the issue of crank hub slip. This problem can lead to timing misalignment, potentially causing piston-to-valve contact and severe engine damage in extreme cases.

Why Does This Happen?

The stock crank hub in the S55 engine lacks a secure mechanical connection to the crankshaft, making it prone to slipping under heavy loads or after engine tuning.

The Solution:

dtm-tuning offers an upgraded 2 or 4 Pin Billet Keyed Crank Hub. This innovative component provides a reliable connection to the crankshaft, eliminating the risk of slipping and ensuring stable engine performance, even under extreme conditions.

Benefits of Installing the Upgraded Crank Hub:

- Enhanced Reliability: Eliminates the risk of crank hub slip and associated engine damage.

- Tuning Stability: Ensures reliable performance when increasing engine power.

- Durability: Made from high-quality materials for extended lifespan.

When upgrading the Crank Hub in the S55 engine, it is essential to replace the crankshaft bearings to prevent premature engine wear. Increased loads after installing a new Crank Hub can lead to greater friction and damage to the bearings, especially if they are already worn.

Installing the upgraded crank hub from dtm-tuning is a must for BMW S55 engine owners, especially those who plan on tuning or frequently push their cars to their limits. It ensures your engine's safety and gives you confidence in its performance.
