[QUOTE="YJcharlie, post: 427866, member: 19246"] Hello Old McDonald, We share a very similar story. I'm 59, never had a jeep before but always liked how they look. I was ready for a winter project so I picked up an 87 YJ shown in my profile pic in a trade. So, basically free for me. I had the exact same question as you since I could see the jeep was lifted but didn't know how much. Turns out you just look at a few things. First thing, put the jeep on some nice flat ground. Then measure from the lowest spot under the door, that bottom plate, not sure what its technically called, but measure that to the ground. Make sure your tires are fully inflated. That is your overall lift. Stock on these yj's, as far as I know was 19 inches. So say you measurement is 25 inches that means you have a 6 inch overall lift. Then you want to see what is really lifting your jeep. Its your leaf springs, tires and shackles typically, or a body lift as well. My shackles measured 5.5 inches from the center of each bolt. Stock would be 4 inches. So that 1.5 extra inches divided by 2 and that was 3/4 of an inch from the shackle. Now I'm running 33 inch tires and fully inflated, they measure 33 inches. Stock are 29 inches. So 33-29 is 4, but divide by 2 and thats 2 inches for the tire portion of the lift. So, 3/4" from the shackle, 2 inches from the tires, that leaves 6" - 2 3/4" = 3 1/4" left over which is the spring lift in my case. My leaf springs were in bad shape, so I ordered new ones that were for a 2.5" lift. After installing them, the jeep steers really bad so I just removed the long shackles and went to stock one's and that fixed my caster issue and the jeep drives much better. Still not great but I haven't got it aligned yet. Thats next Wednesday. So I did end up lowering the jeep some but I really want this to drive as good as a straight front axle vehicle can. I'd be better off with 31's as well, but these wheels are like brand new and probably 200 bucks each, and were on it when I got it.
