Great product. No gripes other than that it didn't work with my setup. If you have some steering angle mods done to your tt01, these may limit the amount of lock you can get. You'll still definitely get more lock than the stock dogbones, but you may want different universals that can achieve a more aggressive angle. I guess it depends how aggressive your steering angle mod is. I've got all the active hobby steering stuff and upper arms. I ended up just giving these to my buddy with his stock tt01 to give him a little smoother power delivery when turning and a little more steering angle.
Really nice shafts. They come mounted and even greased in package, so you just have to remove your old shafts and put this ones in. Before this shafts i had the original dogbones and cups. And with some other modifications I can really notice I have more steering angle.
