Guys, as has been stated many times... the CBC and the Spline Lock together are a complete solution that address the multiple causes of slipping the hub.

While having one solution is better than nothing, the complete and proper fix is to use both a spline lock and a CBC.

The Ghassan car did not use a CBC, and also used a damper we have found to be associated with very high vibrations (we ran one before on our shop N54... took it off as high rev vibes were enormous).

The reported other crank hub slip also did not have a CBC. With the crank bolt loose, you're going to have hub slip.

Again.... a complete solution is the best path forward. Spline Lock and a CBC together.

A few guys asked "why sell them separately?" Not everyone wants to do the install, and a CBC by itself will stop the bolt from vibrating loose. That "something" is better than nothing and the cost is minimal. Not to mention those that already bought a CBC and just want a spline lock. Again though.... really need them both to fully resolve the issue, which should be clear.
