RE 3.5" lift only 2.75" net lift???

I just bought a 5.9 limited with an RE 3.5" super ride lift. I also picked up some JK rubicon wheels with 255/75/17's(32x10.5), and ordered 1.25" adapters. I measured from the top of my wheel to the fender, and added half the diameter of the outside of the wheel to get my hub to fender numbers. I'm sitting at 20.75" in the front and 21.125 in the rear. From looking around it seems that a stock zj is around 18". So I'm only up 2.75" in the front and 3.125 in the rear. I have an arb bull bar on the front and will be adding a winch, I also plan to add a roof rack with a hi lift, shovel, spare, etc.

At 3.5" of lift only 31" tires are recommended, I'm going to have 32's. Should I add some spacers? If so, should I run a .75" spacer front and rear? Front only? Does anyone make a spacer between .75" and 1.75"? Does a .75" spacer give me .75" lift or is it more?

Measure actual hub to fender to determine lift.

How is the radius of the wheel plus the distance from the top of the wheel to the fender different? The wheel measures 16.75" lip to lip, making the distance from the center of the hub to the top of the wheel 8.375". Then I measured the top of wheel to the fender front 12.375" and back 12.75". Add the two measurements and you get hub to fender of 20.75" front and 21.125" rear. Unless my basic math skills are wrong thats a pretty accurate way to measure hub to fender. Unless eyeballing the middle of the hub that's 5" inside the tire seems more accurate?

just post a picture.

thres a bunch of us that can tell you what life you have just by the stance and what parts are installed.

i don't trust 'jeep people' math skillz show your work; yes this is highschool again. only partial marks.

plus what kind of bull bar do you add a winch to? is ita an ARB winch bumper? if its heavy on the front it will make your jeep sag a good inch at least.

I need to take a pic on flat ground to show the stance. I have an arb winch bumper, that arb calls a deluxe bull bar. Do you want pictures of me measuring? I don't think I have that many hands. I'll also be adding a winch to the front and will need to make up for that as well. As far as life style, I bought it as it is now. So you can judge the previous owner.

you have an ARB winch mount bumper? ok that makes sense.
those will bring your front end down a bit, almost the exact measurements you give.
plus, in the rear, they wont' measure a true 3.5" because they lift the front more than the rear to take out the 'rake' of a vehicle. so the front would be 3.5" but the rear might not come up that much.

so ya no problem. just how they sit. if you really want to fix it, add a 1" spacer to the front.
and your JK takeoffs will work just fine and look really good

i bet if you took off the bull bar, it would sit closer to 3.5 inches.

I just noticed that my front axle is offset to the passenger side. Is that normal?

Do you have an adjustable track bar? If you do it needs adjusting.

That might be sagged a tiny bit, it sits close to what mine was when I was at th same height with the same kit on 31s. (Can post a picture tonight)

The ARB sags it a lot, it will sag more with a 100lb winch in here. I'd toss 4.5" springs in the front and a 0.75" spacer in the back. I'd also double check the tire size, you said you are getting 255/55r17 tires? Those are a 28" tire, the 255/75r17 are a 32" tire

i vote arb bumper is heavy as s*** and sags your springs. Think of the amount of weight from your big ol' motor plus that big bumper all the way out there. I agree, 4.5" springs in front and .75 spacers in rear.

I don't have an adjustable track bar. It's been relocated per the re directions. And since its sitting lower than the 3.5" that re intended, maybe that's pushing the axle over?



I'd rather save some money and run spacers. Can I cut down a thicker spacer for the front and run .75" in the back? Or does someone make custom thickness spacers?
