if not bumpstops, what do you think stops the track bar from hitting the diff, or stops the track bar from hitting the tie-rod? what stops the shocks from bottoming out? what prevents other suspension interferences? what stops the springs from over-compressing at full bind? what stops the tires from hitting steel?

I realize the bump stops keep that from happening but couldn't u also leave in the springs and use a lift or ramp to cycle the suspension..like on mine I used a ramp and everything clears other than the shock is what is goin to stop my rear up travel so I know I gotta extend them..I know that sound dumb bit its all I have right now living on the road with work don't have acces to a garage right now

you use a ramp/bump/pothole to cycle the suspension everyday you ride on the road.

problem is, you need a way to simulate that in your garage. You have to make the frame and axle come together somehow...slowly, in a controlled manner.

And since the springs hold the frame off the axle, the easiest thing to do is remove the springs. Support the frame, drop the springs out, then use a floor jack (or a lift of some sort) to push the axle up to full bump and full flex. You also check tire clearances, full droop, brake line length, etc at the same time.

If you're looking at flex on an RTI ramp, hill or something, you're not even getting half the story.

your jeep isn't an exception to the rule, you just don't comprehend what this thread, and others, are trying to teach you.

Cycling without the springs allow you to check clearances when both sides of the axle are at full bump. You can't do that in on a ramp.

I bet that a lot of the people who have issues with the track bar and diff clearance could go on a ramp and have everything clear just fine.

Plenty of guys run 3" springs with 1" drop without vibes. I did it for 3-4 years and had no vibes.

yup, the thread I linked for him above, the exact post in fact, describes just that and shows pictures of it.

you can lead a horse to water, but you can't make em drink.

I've been reading through the threads and I'm still a little confused.

My setup
33's, AEV 3" Springs, Rancho rs9000xl, 1.25BL, 1"MML

Rancho rs9000xl shocks
F Compressed: 16.110 Extended: 25.970
R Compressed: 15.290 Extended: 24.150

F 16.110 - 13.50 = 2.61 - 1.25 BL = 1.36 BS?
R 15.290 - 12.50 = 2.79 - 1.25 BL = 1.54 BS?
