Hi new member here!!!

I recently installed the AC articulator lift. There seems to be a 3" difference in ride height from front to rear. Will removing the overload springs reduce the lift in the rear? It looks a little goofy as it sits now.

Any feedback is much appreciated.

Well, the OL leaf is ~ 1" thick...but at the bottom of the pack, and only active when the suspension is crashed flat...

Removing it will essentially just raise the leaf plate up ~ 1", which adds droop, and remove the road grader-like leaf from under there, improving ground clearance, etc.

It won't lower your butt though.

The FRONT end probably needs to come up...did you crank the t-bar to get ~ 1/2" - 3/4" gap on the upper bump stops?


For perspective, the front should be ~ 1.5" lower than the rear, if measured at the front/rear of the steps or sliders, to the ground.

Thanks for the input, I'll measure the distance at the front bumps tonight.

Due to the angle, its easiest o find something ~ 1/2" to 3/4" thick to pass through the gap like a feeler gauge...than to try to hold a ruler to it, etc.


If you can raise/lower the feeler in the gap, then the gap is too big, and you have room to shrink it to that size to raise the front end some more w/o running out of alignment adjustment room/making the UCA bounce the stops when driving, etc.

Are you talking about the bump stop located on the lower control arm?

The distance between the upper control arm and the bumpstop indicated by the red arrows.

The pic is correct - the upper bump stop I mentioned is the highest (Upper) one...which, counter intuitively as far as the name goes, is what limits DOWN travel.

The UPPER control arm moves DOWN when the truck is raised (The truck goes up, but the tires stay on the ground...so the arm has to swing down to allow that, etc...)

The upper bump stop STOPS the upper arm on its way down, to prevent you from drooping further than the CV's, etc, can handle.


The gap between the upper stop and the pad on the upper control arm (Shown in pic above) is what you want to be the size I mentioned.

Too small a gap, and the arm will hit it too often, and, you'll also have too little down travel left to follow the terrain well, etc.
