Think I may have found a D60 with dually hubs for my dually, and I'm thinking if I'm going to do a solid axle, I might as well do an RSK while I'm in there. I've been doing some digging and it looks like the Precision Metal Fab kit gets pretty good reviews. I'm reading a lot of folks doing the upgrade U and V code Super Duty springs also with good results. Just wanted to see if anybody over here has done any RSK work. I have an intercooler and it sounds like there's probably room with the PMF kit, but if anybody has any input I'm all ears.
