Planning on installing a Teraflex Performance leveling kit to make up for my upcoming of putting on new bumper and winch and getting things needed ( I get so supervise son in law and my friend as my current heart problems make me pretty much useless in helping, want things to go smooth as possible for them). I am sure its been asked before but how high do you have to lift the jeep, 4 door rubi, to get springs out and back in? Making sure my floor jack will lift jeep high enough to put on jack stands to drop the differentials far enough. Think my max for my floor jack is 19 3/4 inches. Is that high enough?
