I'm not one of the "most people" I guess. I used them on my other jeep. If you're like me, my welds look like pigeon shit or, maybe you don't have a welder. They are handy and worked well. You may need a 3/4" spacer up front to re-level the jeep afterwards. I'm not sure if mine were RC or not, though. But, they are probably all about the same. You'll need to re-check pinion angles too. These will save you from grinding the lips on your spring buckets too, if that is a problem for you.
