Expert's advice:

In the BMW S55 engine, camshafts are connected to the crankshaft via a camshaft chain. This chain, in turn, is connected to a sprocket that’s mounted on the crank hub. In stock form, this sprocket is not fixed on the crank hub, putting tuned engines at considerable risk of failure. If the sprocket shifts out of alignment due to increased power, so does the engine’s timing.

The MSL Crank Hub offers a vast improvement in terms of engine safety. We recommend the crank hub modification for heavily tuned engines that put increased levels of strain on the crank hub and sprocket.

    With Mosselmans' performance package I exceeded even more than the company advertised on their website! The information sharing process was easy and hassle-free. Excellent customer service from Leon and his team!

    Mosselman tuned my BMW 318d today. What a result, it became a completely different car! Very professional company and friendly staff. This was my second car here and again they have exceeded my expectations. Thanks!

  • Rob M.

    Very happy with my improved car, the car reacts better on the throttle and is very direct. Also, the exhaust sounds better!

    Visited Mosselman on May 24th for the chip tuning of my 135i, great result! The adjustment is great, when will you post the photo on FB :)?

    After 1,5 years still very happy with my iTronic. By far the best upgrade I could have done with my BMW 340i.
