Description

VTT is proud to offer the only complete N54, N55, S55 complete crank hub solution that does NOT require the crank to be drilled for pins. Our hub uses our proprietary “Spline Lock” technology that uses high tolerance machined splines that press into the crank, and positively lock the hub to the crank. We spent many months testing, and retesting this design, utilizing well over 10 different samples to come to our final production version. During testing, our final hub managed to break our testing rig before slipping. These have been bench-tested, and real-world testing on the VTT N54 race car spinning 8K RPM and making well over 900WHP. This technology means our hub installs the same as a stock hub, with no drilling of the crank, which means MUCH less labor is involved and is reversible is ever wanting to be uninstalled leaving no holes in the crank. The “Spline Lock” is ONLY available with the VTT Crank bolt capture for the ULTIMATE Crank Hub solution for your BMW. These parts are designed to be used together, and the spline lock should not run without the CBC

VTT “Spline Lock” Crank hubs are CNC manufactured from 440C tool Steel with a Rockwell rating of HRC60 for the ultimate in durability, and toughness.

We offer the hubs in 4 ways.

We suggest the Crank Hub System ONLY be installed by a qualified shop or technician. Timing tools are 100% REQUIRED if installed improperly engine damage may occur.

DISCLAIMER: The no-slip guarantee is ONLY in place when installed by a CERTIFIED VTT Install center. Outside of that VTT is not responsible for any engine damage caused by improper installation, or misuse of the crank hub solution. The product comes with no warranty as it is intended as a race part only. Our install guide is meant to assist a skilled technician when installing this part. Procedures differ from the factory and should be followed according to the guide. We cannot warranty the OEM parts sold with these kits, if an issue is found we can speak with BMW about a replacement.
