I did my front end today- finally got those lock-nuts loose. I could only get about 3/4" lift before I ran out of room between bumpstop-UCA (1/2" remains). They must have been sagging, cause there is now the normal 1" difference between front and back of the truck.

So, I didn't put my shackles on. Not sure what to do next. I'm guessing re-indexing them may allow me a little more lift? Or maybe not?
