VTT BMW N55/S55 Crank hub bolt capture kit

Worried about your BMW S55 / N55 crank hub spinning? All the reports of spun hubs making you nervous about turning up the power? First-aid is here.

If you want a little extra security for your S55 crank bolt but you’re not able to fit the whole VTT Crank hub solution, then here is an easy, and cost-effective way to do what you can to prevent the issue. The VTT S55 crank bolt capture. slips over the head of the crank bolt fully encapsulating it, and locks it to the crank hub, meaning it cannot back out no matter what.

The VTT-CBC is 100% Billet Aircraft Grade Aluminum, Anodized black to protect it from the elements, and give it a stealth look.

While this is not a full fix for all crank hub spinning issues, we have found most of our issues have stemmed from the bolt itself backing out, and this is a great way to keep that from happening. Extremely lightweight at only 1.3 Oz’s it adds virtually no weight to the crank which is important for balance and vibration.

Fits for example:
BMW M2 + Competition
BMW M3 + Competition
BMW M4 + Competition
and basically any other BMW S55 or N55 powered vehicle
