The fronts were on a Sport. The rears were never installed, as they were a replacement that I did not get around to installing yet. I had removed all the RK springs before getting the replacement rears. While those were out, I had Mopar lift springs in it. I much preferred the Rock Krawlers for ride quality and offroad performance. In that they had great extended length.How did you like these springs compared to stock? Were they on a rubicon?
