Mosselman MSL Timing Hub Solution for BMW F80 F82 F87 S55 Engines

Protect your S55 from timing drift and sprocket movement with the Mosselman MSL Timing Hub. This is the sought-after crankshaft hub solution for BMW F8x owners who want reliable engine timing security on road, fast-road and circuit cars. Ideal for remapped and high-torque builds, the MSL hub addresses the well-known S55 timing concern by dramatically improving sprocket retention and cam phasing stability under load.

If you are searching for a BMW F80 timing hub, BMW M2C timing solution, BMW M4 timing gear, F8x crankshaft hub assembly or an S55 timing chain hub that resists slip, this genuine Mosselman part is the trusted choice. We run this hub on our own S55 projects at MJ Modifications and our customers have been consistently impressed with the confidence it delivers.

Why the S55 benefits from a timing hub solution

The factory arrangement allows the cam chain sprocket on the crankshaft to shift under higher torque and aggressive use, which can alter engine timing. The Mosselman MSL hub is engineered to keep the sprocket firmly located, helping to prevent timing misalignment and the costly issues that can follow. It is a must-have reliability upgrade for tuned S55 applications, from spirited road cars to track day builds.

Key advantages

• Timing stability - Helps safeguard against crank sprocket movement and cam timing drift on the S55.
• Built for power - Suits remapped cars and higher torque setups where the standard arrangement is under greater stress.

• Precision engineered - Designed by Mosselman for consistent performance and long-term reliability.
• Proven with enthusiasts - Used by us and our customers on F8x platforms with excellent feedback.
