Quality product but instructions and parts labeling suck. Even though each set is individually boxed, it takes a bit of work to figure out which bag goes with which piece. Install PITA! For the control levers you have to use old metal bushings. As a result, I had to burn out the old bushings with a propane torch. If I had to do it all over again, I'd probably just pay a little more and buy pre-assembled upper and lower arms.
