I recently installed Quaratec HD leaf springs and they put the back up to what I think would be a 3" lift (20" from center of axle to edge of stock fender flare). Should I expect the leafs to stay at this height or will they settle at a lower height? And if they are going to settle about how long does it usually take?

 

Well.. The HD's are probably a bit better than the medium leafs, which will sag out pretty bad.. Maybe after a year or so? It depends on how much you wheel/flex out/haul stuff..

Oh and best way (IMHO) to check lift height is to measure from top of axle tube to bottom of frame rail. Front is 6.75" and rear is 6". Anything more is lift.

 

It is a pavement pounder cause it my DD but I do hit up some fire roads if I get a chance(not many by me). Ill have to try your measurements to see where Im at. I would like to get matching height coil springs or spacers to level it out someday.
