Have you decided to swap out your stock BMW crank hub for a new spline lock crank hub solution? You’re not alone in making this upgrade, especially if you drive a BMW with a high-performance engine, like the N54, N55, or S55 platform.
The stock crank hub might not meet your needs in terms of safety and reliability, especially if you’re pushing big power and higher RPMs. You want to know you can push your vehicle without your crank hub slipping. Here’s why you should choose a BMW crank hub with spline lock technology.
Spline Lock Over Pins
There are a number of crank hub replacement options on the market, but many require pinning or welding. This adds a layer of complication to the installation process, which may require drilling for a proper fit. Pins can also fail and make future upgrades more complicated.
N54, N55, and S55 crank hub upgrade options with spline lock technology offer reliability without the need for pins or drilling. Instead, you get a crank hub solution with a precision-engineered spline system designed to press directly into place.
Why a Spline Lock Solution Matters
Why does spline lock technology matter? It comes down to an “interference fit.” The spline lock presses into the crank snout, displacing metal, and locking itself into place.
While conventional crank hubs use small locating pins to counteract potential slipping, a spline lock crank hub is specifically designed to press its grooves into the crank snout, creating a more precise mechanical bond with full 360-degree engagement, eliminating the risk of slipping.
A More Direct Installation
When you eliminate the need for crank drilling, along with pinning or welding, the result is a simplified installation process. There’s less work and less potential for error. Plus, this can reduce labor costs on your end.
The installation of a BMW S55 crank hub solution with spline lock technology is also fully reversible. Should you need to remove it for any reason, you can do so with relative ease. That’s a testament to the versatility of this crank hub solution.
