I installed the 3.5" TM Econolift with Ironman springs and shocks about 30k miles ago and I'm now sitting at 21 in the front and 22 in the rear. I've been in Korea so my wife has been driving the Jeep and it has not seen off-road action since the lift was installed. Is it normal for it to sag that much that fast? I'm about to buy tires as my stock size tires are pretty worn but seeing how much lower it is I don't think the 32" (ok 31.75) tires I wanted are going to fit.
