MMX BMW S55 1-Piece Crank Hub is an essential modification for the S55 engine. It's no secret that the S55 is prone to spinning its crank hub resulting in quite a hefty repair bill. Once the crank hub spins, the engines timing is completely thrown off resulting in pistons hitting the valves and complete engine failure. Investing in preventative maintenance could make all the difference!
As a preventative measure, MMX have developed this one-piece crank hub upgrade to ensure the friction plates cannot slip, delivering a substantial improvement in reliability versus the OE version.
The MMX Performance one-piece crank hub is machined from billet EN36 that's been heat-treated with a 0.75mm case hardening, making it incredibly strong and durable. Combine this product with the MMX S55 crank hub capture plate for the ultimate solution.
