Upgrade Your BMW’s Crank Hub with Vargas Turbocharger Technologies

Do you drive a BMW with an N54, N55, or S55 engine, whether it’s stock or lightly modified? If so, the crank hub is one component you should keep an eye on. When you push these engines to higher RPM and enjoy intense driving, you want to know the hub that connects your crankshaft and timing system isn’t going to slip.

At Vargas Turbocharger Technologies, we have developed a dedicated solution for this problem: the VTT™ N54/N55/S55 Spline Lock Crank Hub Solution. Here’s what sets our BMW crank hub fix apart from the stock part and other options on the market.

You Get a Complete Crank Hub Solution

We designed our kit to be a true out of the box answer. It’s the only N54, N55, and S55 engine crank hub upgrade that arrives as a complete package and installs without any drilling into the crank. The process is similar to a stock-style installation, which helps keep things clean and repeatable for professional technicians.

You can also tailor the package to your build. Choose from several configurations, including the crank hub on its own, the hub paired with our VTT™ Crank Bolt Capture (CBC), or a more complete bundle with additional hardware. If you want maximum security, the full package with CBC is the way to go. If you are planning a staged build, you might start with the hub and add the CBC later. Whatever your goals, we give you options to match.

A Next Level Option with Spline Lock Technology

The key to our installation process is our proprietary Spline Lock Technology. Instead of relying on drilling, pinning, or welding, we precision design our crank hub so it forms a positive mechanical connection with the crank snout.

During installation, the splines on the hub engage with matching grooves in the crank. This creates a secure mechanical lock that keeps the hub from rotating independently, even at high RPMs and under aggressive load. The result is a significant increase in reliability and a real solution to the slipping issues that these platforms have become known for.

A Crank Hub with Serious R&D

We invested extensive research and development into our N54, N55, and S55 crank hub solution. That included months of design work, prototyping, and real-world testing to confirm that the hub performs as intended under demanding conditions. Our goal was simple: create a crank hub upgrade that you can install once and trust for the long-haul.

For the best results, we recommend having the hub installed by a professional using factory timing tools. When you choose a Certified VTT™ installation center, you also qualify for our No Slip Guarantee, which adds even more confidence to your build.
