Front seems to be very well documented


But how do we measure the rear using the same concept ?
I've never checked my lift height, specially the rear height, because i never took measurements stock to compare, so i always say 2" lift in general :)

Thanks a lot.

I have 20 1/2 front and 7 1/4 rear, so pretty much 2" lift.
Thanks one more time jadmt.

What is that even a picture of?
Appears to be the lower edge of the upper bump-stop flare in the top.

Lower would likely be the bump-stop on the top of the axle.
I presume these measurements are the results of the BEFORE LIFT?
Getting after installation measurements would give you the suspension lift overall. But remember your tires only effect the lifting of the axle.

Breakover is an important area to determine as well. Determine the wheel base (axle to axle) and divide in half. At the halfway point measure the lowest part of the frame or skidplate to the ground before and after.

So using this info my lift gave me 2.5" in the front(my measurement was 21) but only 1" of lift in the rear (my measurement was 6.25) I have a 2015 JKU Sahara and i installed the 2.5" Teraflex lift. do these numbers seem right?

Most lift kits on the market eliminate the rake and level the jeep. If you are level, it should be ok. If the front is nose up, or if you rub, then you will want to add a spacer on the rear springs.

My Teraflex 2.5 measures exactly the same as yours. I have heavy bumpers, winch, skid plate, bumper tire carrier. It sits level I think that's the way its designed. I did have 3.5 at the front before I added all those heavy accessories.

You have someone with a stock wrangler, same model as yours measure from the top of the WHEEL (not tire - this takes tire size out of the equation) to the lip of the fender. Then you measure yours. The difference is your lift. You must be on level ground and you must have the same wheels (tire size doesn't matter).

I have the Teraflex 2.5-inch lift kit that comes with springs and shocks. It's the kit that's about $850 I believe on quadratec. It's installed on a 2013 JK Sport two door, and was already installed when I bought the Jeep.

I just measured today, and it appears to have given me a 3.5" actual lift in the front. (Shocks measured right at 22" and the coil was right at 13")

It looks like about a 2" lift in the rear, as it's right at 7" from bumpstop to frame.

Looks like I may need a spacer in the rear. See the attached pictures and give your opinion if it's level or sagging a bit in the rear.

If it is, it could be because of the heavy spare tire and bumper. And my rear shocks are absolutely shit, which may allow it to say a bit. I'm getting those replaced probably next week

It looks fine to me, but it ain't my Jeep. If you want the rear up a half inch or so, add a set of spacers to the rear.
Keep in mind that when level the gap between the front tire and fender will be a little larger than the gap between the rear tire and fender. The two fenders, front and rear, aren't identical.
Whatever you do, make sure your headlights are properly adjusted. Leveling the Jeep, or adding spacers to the rear of the Jeep, will change the aiming of the headlights.

That's a good point on the headlights. Had not even crossed my mind!

You can only measure it to see where you are currently at. From there you can probably figure out where you started.
Also, the amount of bump stop extension MAY help you figure out what lift you have.
You can also remove your shocks to see what their extended and compressed lengths are.
But why does it matter?
You may want to start a thread where you can measure, post the measurements, and perhaps include pics of your lift. You can also include what you want.

Have a 2.5" RE progressive spring lift installed, heavy bumpers, tire carrier with 35", tuffy security rear trunk, winch up front, soft top on and I'm getting a full 2.5" in the front and only about 0.75" in the rear. I want to add some spacers for some extra height, I guess I should go with something a little taller in the back than the front

You can add spacers to level out the suspension or to compensate for extra weight. Most lifts are going to lift more in front than in back, usually about a inch to inch and a half difference. That is to level out the stock rake they come with. Yours sounds a bit extreme, and if that is what you got it sounds like it sits front end high.
You can just add a set of 1" spacers in back.
Your rig doesn't sound very heavy, but the RE springs aren't known as overly great springs, so you get what you pay for sometimes.

I sent an email to Rubicon Express to see what they say. Here are some photos of my rig. You can see I measure 21" in front and only 6" in the rear. When I place a level on the trunk ledge (where the soft top meets the side) is shows almost perfectly level.
