Description
VTT is proud to present the ultimate crank hub solution for BMW N54, N55, and S55 engines—the VTT Spline Lock Crank Hub. Unlike traditional solutions that require drilling the crank, our innovative hub utilizes exclusive “Spline Lock” technology. This approach ensures a secure, slip-free fit with no need for crank modification.
Key Features:
- Spline Lock Technology: High-tolerance machined splines press into the crank, positively locking the hub in place. The hub is driven deeper into the crank by rotational forces, preventing slippage.
- Testing Excellence: Our design has been rigorously tested, including real-world testing on the VTT N54 race car, achieving 8K RPM and over 900 WHP. The hub even broke our testing rig before slipping.
- CNC Manufactured: Made from 440C tool steel with a Rockwell rating of HRC60 for exceptional durability and toughness.
- No Crank Drilling Required: The hub installs like a stock hub, minimizing labor and allowing for reversibility without leaving holes in the crank.
Available Options:
- Hub Only
- Hub with VTT Crank Bolt Capture
- Hub Plus OEM Bolt, OEM Oil Pump Sprocket, and OEM Oil Sprocket Retainer
- Hub Plus OEM Bolt, OEM Oil Pump Sprocket, OEM Oil Sprocket Retainer, and VTT Crank Bolt Capture
Installation Note:
- Qualified Installation Required: The Crank Hub System should only be installed by a qualified shop or technician. Timing tools are essential. Improper installation may result in engine damage.
- Disclaimer: VTT is not responsible for engine damage caused by improper installation or misuse. The product is intended as a race part only and comes with no warranty. Follow the provided install guide carefully. We cannot warranty OEM parts included with these kits.
