Description
VTT proudly offers the only complete crank hub solution for BMW N54, N55, and S55 engines that does NOT require drilling the crank for pins. Our innovative “Spline Lock” technology features high-tolerance machined splines that press into the crank, positively locking the hub to the crank. After extensive testing and development, this design has proven to be robust and reliable, breaking our testing rig before showing any signs of slippage. The VTT Crank Hub Solution has been bench-tested and real-world tested on the VTT N54 race car, spinning at 8K RPM and producing over 900WHP.
Key Features:
- Spline Lock Technology: High-tolerance machined splines press into the crank, providing a secure, positive lock without the need for drilling.
- Durable Construction: CNC manufactured from 440C tool steel with a Rockwell rating of HRC60 for exceptional durability and toughness.
