same, I bought them because I wanted the tru track then when I broke front arms I bough RPM to match the rears.
RPM arms are a good investment if you planing to bash your truck with some intent. If you only planning to run it up and down the street and over speed bumps and the like then would stay with stock arms.
Always get a 2nd Opinion!
