If you drive a BMW with an N54, N55, or S55 engine, replacing that vehicle’s crank hub makes sense. You may have heard about concerns online regarding the stock crank hub. These concerns generally relate to reliability.
Pushing your BMW to its limits puts a lot of strain on the crank hub (and its connected systems). Having a reliable crank hub makes a difference in the security and longevity of your car’s high-performance engine. What should you look for in a N54, N55, and S55 crank hub upgrade?
Advanced Crank Hub Options with Impressive Features
There’s a variety of BMW crank hub replacement solutions on the market today. They exist to address those reliability concerns. But not all of them are created equally. There’s a difference in materials, overall design, and how replacements are installed.
Look for an advanced N54, N55, S55 crank hub solution with spline lock technology. A spline lock design blends resilient materials (such as heat-treated 440C tool steel) with precision-machining that locks the crank hub into place. There’s no drilling, pinning, or welding required.
Reliability When You Push Your BMW on the Road or Track
Whether your BMW is a daily driver or you take it out for time trials on the track (or both), reliability means a lot when you push the RPMs and WHP. The more you ask of your vehicle, the higher the stress on the crank hub.
A new crank hub with a spline lock design brings enhanced reliability to your driving experience. If you’re pushing the speedometer on the track or frequently shifting in any driving situation, the goal of the hub is to avoid slipping. By improving the mechanical security of the timing interface, that’s exactly what spline lock technology addresses.
Eliminate Slipping to Protect Your Crankshaft and Engine
One reason you’ll find online discourse about the stock crank hub comes back to common concerns related to crank hub slip. When the crank hub slips, it can throw off engine timing, leading to reduced performance, inability to start, or a rough idle. In some cases, slippage results in significant engine damage.
Replacing the stock with a new N54, N55, or S55 crank hub helps eliminate slipping. The reliability factor helps protect the crankshaft and engine from potential damage. That’s reliability you take advantage of every time you drive your BMW.
