I've got an 09 Pro-4X. Before I became a member of this website and learned about PRG, I bought a leveling kit from Superlift because they're local and I was riding by there anyways, so I picked it up straight from Superlift's office. After installing it, it looked great, but had major coilbucket contact. By this time I had become a member on this website, so I knew people were talking about grinding off their upper control arm lips. I wanted to do one better, so I called Superlift and asked them if they had a fix. They said they hadn't heard of the problem, so they asked me to bring the truck to them and they'd fix it. They were glad that I called so that they could be made aware of the problem. All they could see to do was either grind the lips or get shorter shocks (they designed the kit on an '05 or '06, which had 1/2" shorter shock, which causes the major cb contact). I told them they could do the grinding and we'd call it even. They did, and made it look reall good. The cb contact was minimized, but still isn't gone. What would y'all do? I've dropped $180 on the kit, installed it myself, took it over there for them to fix, and I've still got the problem. I want to end up with at least 4" of lift, eventually, but for now should I put another brand's leveling kit on there or should I take the kit off and install Bilstein 5100's? Like everyone else on here, I want the most lift for the least amount of money and I think I've just wasted $180.
