It's realy more of an issue with GM's. The angles get bad with any brand when lifted, but its worse due to the GMs being spring over. To clear the leafsprings you can't get the DLE out to the end of the tierod. The Fords are coil front and have no issues w/ interferance. Jeeps, including FSJs, are spring under so it works OK there, too. We used this set-up when swapping a J10 D44 into the front of a Z-71. Keeping it spring-under allowed it work just fine. Its been on there around three yrs, running 35s the entire time, w/o any issues. Of course, YMMV.
