The axles work but Redcat is junk and the CV axles will still break!
The installation was a little bit difficult due to the instructions but it is not so difficult that I couldn't figure it out. I did the upgrade for durability because the CV axles would break during use, this happened a total of 4 times before I did the upgrade and then twice after the upgrade so I junked the Redcat and went with the Traxxas TRx4 sport. My friends axial scx10 II and my Traxxas has been unstoppable compared to the Redcat plus it was cheaper to just buy the Traxxas that comes with the portal axles. Do yourself a favor and don't buy Redcat junk.
