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 labour 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. This Kit comprises of VTT Crank Hub Upgrade, OE Oil Sprocket, OE crank Bolt and Capture Plate.
