Hey guys, Over the summer I put on a RE4.5'' superflex. I bought some ProComp shocks to go with it. In the rear, the shocks would not go on in the virticle position because they hit the spring perch. I ended up putting them on upside down. I have started to notice that they act much weirder than the correctly installed fronts. Are there special shocks that can only be inverted, and has anyone else had this problem with interference in the back?
