Honestly, I did it all by myself and it kicked my butt. It was all straight forward and bolt on but some of that stuff is heavy and not easy to do by yourself. It took me about 13 hours to do the front and rear. You need shock 20057 if you want the same N2.0 for the rear. I asked the RCX tech department. Order new springs if you want it to sit level. Overall, I am very happy and would recommend Rough Country.
