VTT Crank Hub V2 Upgrade – BMW M2, M3, & M4 (N55 & S55)

£899.00 Inc VAT

Description

We are finally pleased to release a crank hub upgrade for the BMW M2, M3, & M4 (N55 & S55)

Joining with VTT we are 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 which press into the crank, and positively lock the hub to the crank.

The splines are machined in such a way that rotational forces drive the hub, and splines deeper into the crank meaning when the hub encounters a situation that would normally slip a stock hub the splined hub is driven into the crank to keep it in place (much like a splined extractor).
If you are tuning your N55 or S55 or using hard on track we recommend fitting this product to ensure your self against an expensive engine failure if the OE crank hub was to fail

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 tested 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, 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. Couple this “Spline lock” hub with our VTT Crank Hub capture for the ULTIMATE Crank Hub solution for your BMW.

VTT “Spline Lock” Crank hubs are CNC manufactured from Harndered 17-4SS for the ultimate in durability, and toughness.

Fitted price includes:

Labour
Genuine cam cover gasket set
Genuine crankshaft seal
Replacement HPFP Cap 
Genuine BMW Coolant
