I went ahead and bought another full set of Tekno's for my Slash 4x4. They have yet to show any signs of wear on my Pede 4x4, and it seems like people just don't have many failures. I also have the old MIP CVD's, and can say the Teknos CV seems more heavy duty. The pin is a bigger diameter, and none of those little set screws. I'll take some pics before I install them. But after running the 2400 on 4s with the big old Trenchers, I ended up with 2 messed up hex nuts, the pins stripped the inside of the hexes so Aluminum hexes are also on the way .

BTW the other things I have upgraded are my arms to RPM and both shocktowers, the front to aluminum because I had it, and I shattered the rear, so went RPM. OH, yeah I bent a shock shaft, but that was my fault. Other then that the truck has taken a beating.
