Your upper ball joints are going to hate you, so yes. Should've gone with a different kit IMO.
I completely agree that their older kits are fine. But the kits for the new platforms are poorly designed. Take a look at the instructions for the 7.5" kit. RC's 3" kit has a well documented history of flaws. RC apparently doesn't make them like they used to.not trying to cause any arguement but your not going to find many people on here that like RC kits, i've had 2 of them and no problems with either or. i also was on a budget and they worked out for me the best and like i said i've had no problems with either i've installed.
