Running a around 900 to the wheels on stock driveshaft so I believe it will the time to get this and axles done. I had a QA1 carbon fibe shaft and it didn’t work the 1st one the boot split open spewing grease all over contacted QA1 and send a second and the same thing happened returned both shafts and they said they were going to have to do some R&D and didn’t know when they might have it fixed.
So i am looking for some advice from others that might have done this upgrade? One piece, aluminum, CF or stock ZL1

Any advice will be greatly appreciated.

I had the same issue with an aluminum 1 piece. Company was super helpful, but the boots kept splitting and had a nasty vibration. After swapping it in and out I had them refund me and I just put the stock shaft back in.

I have read about some having vibrations with one piece that why i am actually contemplating going with the 2 pc zl1 shaft and axle.
