this is the one I have always used. it will be in the ball park anyway.

 

What is that even a picture of?

 

Ty sir. i'll measure right now and see exactly what i have.

 

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

 

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.

 

This is super helpful!

 

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

That does look like a lot of lift in the front for a 2.5" kit. I wonder if you ended up with 2.5" 4dr front springs ( they yield 3.5" on a 2dr).

 

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!

 

I have a 2012 Jeep with a rough country lift that is sagged out and worn out I don’t know what the lift size is can anybody tell me how to measure it with it being sagged out

 

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.

 

You may want to start a thread on your questions instead of putting them here in this sticky.
There you can discuss your Jeep and whatever your questions / complaints are.

 

Measured mine according to the diagrams. Front measures 12” and rear measures 5”. I’m a little confused because I would think if someone put a ~3” lift in the front, something would definitely have to go in the rear. Can anyone clear this up for me? Just bought it and previous owners aren’t quite sure of the brand or height. Running 33x12.5x17 tires. Also, it’s a 2 door 2008 “X” trim if that needs to be known also. Thanks!

 

That sounds like a 2.5" lift that is sagging in the rear. Usually a 2.5" lift will lift between 2.5" and 3" up front and 1" - 2" in back. That reduced lift in back helps level the stock rake of the Jeep as delivered from the factory. If the Jeep now sits higher in front than it does in back you can either replace the springs or add spacers to the rear to gain back any lost height (or level it out).
Pictures of the suspension parts (shocks, springs, etc) might help identify it.

 

@Teddybehr11
OK. On the rear, when you measured the height by measuring from the cup for the Jounce (rubber bumper) down to the axle, did you measure to the flat pad on the axle or to the metal bracket bolted to that pad that we call a bump stop extension? I suspect you measured to the bolt on bracket that raises the bump stop pad. You need to measure down to the pad directly on the axle as shown in the diagram. The diagram does not show any brackets or bump stop extensions bolted to the axle, but if any are there you ignore them for this measurement. I suspect you have a 2" bump stop extension that mistakenly got included in your measurement. That means you have about 2" of lift in the back and about 3" of lift up front. That would be typical of a 2.5" lift.
Better shocks sure are an option. A number of vendors offer better quality shocks for a 2.5" lift.

 

There is a raised bracket below the bump stop that I measured from. I’ll have to get back under there to remeasure it, but it is about 2 inches from the top of the axle. Thanks for helping me out! Just knowing that helps to know what parts to get.

 

I got two pictures since it is so difficult to see

On second measurement I would say 9.5” total, so what lift?

 

That certainly is a lot of lift. I would guess 3.5” - 4” lift. Generally most springs deliver more lift than advertised. So a 3.5” lift will usually deliver 4” or more of lift.
So if you are buying new shocks you probably need shocks for a 3.5” lift.
With such a low end lift of unknown origins you may want to consider just getting a quality lift of the size you want. It will probably be cheaper and better in the long run.

 

The problem lies in the fact that the Fox shocks with separate reservoirs I got were only available in 1.5-3.5” of lift, or 4-6” lift

Seeing as I have a bit over 4” of measured lift, I figure the latter would be best.

I am looking at new coil spring options, and I like the 4.5” MetalCloak for price, and there are also 4” Rancho Rear Progressive Rate ones, and also EVO 4” Plush Ride that I saw some favorable reviews on.

New coil springs, new shocks. All 4.5”, I shouldn’t need to do anything else I’d suspect


Just learning this as I go, and replacing the coils isn’t necessary, I just don’t know what they are, so I’m guessing I can replace them with something better for a reasonable price...... I could be totally wrong too

 

x2 24.5 long shock would have you about topped out just parked. also you should have some bump stops. if for nothing else to prevent coil bind. some coils can live with coil bind others not so much.

 

+1, you want the longer ones. Even when I had a RK 2.5" the fronts were longer than the rears. When I went to 3.5" lift I had to change the rears to the longer ones. I have the Fox Resis, 985-24-011 front and 985-24-012 rear.

 

Just double checked. These are the same part #’s. Thanks

 

Whew. Good. Those are what I’m getting. Thanks!

 

Just remember to add bump stop spacers based on the collapsed length of the shock. The 16.85 will need 2" bump stop extensions to protect them. The 14.85 will not require any extensions.

 

Dumb question, but where do I add those? Are they the rubber parts that go physically on the shocks themselves?

 

My girlfriend tested positive today for COVID so thanks to a mandatory quarantine, I will have plenty of jeep-work time


These are bumpstops Assuming the internet hasn’t steered me wrong

 

That does appear to be your rear axle bumpstops. The rubber bumper is attached to the frame, and that flat pad on the axle is what the rubber bumper hits to stop suspension travel. You appear to be stock, with no extensions top side or on the pad on the axle.
For those shocks you will likely need 2” of extension, usually on the pad on the axle.

 

By the way, that is crazy, having that much lift and no bumpstop extensions. I would guess that the shocks are what stops up travel of the rear suspension. Or your shocks are way too short for the amount of lift. Because I have never seen shocks long enough for 3.5” - 4” of lift that compressed to the same length as the stock shocks.

 

Rear has no extension, what about the front?

 

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.

Older thread, but just getting a confirm on measurements. I purchased mine used with no specs included. A lift obviously, but cannot find what kind/amount. The number on the springs offered no help via Google. My shocks measured 21.5" and the springs were 13" parked on level concrete based off this picture. Safe to assume 3" lift kit then? In the market for steering parts and looking for a drag link, will use that to confirm the stock configuration vs need for a top mount. Thanks!!

 

I didn’t do this measurement but I was curious how high the body set on a 2015 wrangler sport soft top with 255x75/17 wheels and it measured 36 inches from ground to fender bottom edge at all 4 corners can you assume this has any kind of a lift on it ?

 

So I installed a 2-1/2” rough Country lift on my 2014 JK 2 door. And it measured 3-1/2” upfront and just over 2 in the back. I have heavy bumpers, winches etc. my shocks are Bilstein 5100 1” to 3-1/2” lift shocks luckily. Just a bit surprised to see my Jeep go from -2” upfront to + 3-1/2” and -1” to +2” in the back. I wish manufacturers (OEM and aftermarket) would be a little mote open about spring rates and measurements. Would be helpful in sorting this out a little easier.

 

Funny you post this.

I just got the mopars installed wks ago and got the new tires on new wheels. Had to not use the new wheels they didn’t look good with my jeep and there was the lugnut thing.

after getting the new tires on the old salta wheels back in the show.

now I got to figure out how to fine tune it so it level and I ok with overall height. I donot care what net height I actually get just that it looks good.

at first it seems too high for 33.0 tires and even though I knew that I planned on waiting to let eyes adjust and see next summer.

thinking about options I prob go with stock mopar/rubicon mopar springs and a 2.5 and .5 spacers on left and a 2.5 and 1.0 spacers on right for gas tank lean. Keep back same with 2 inch mopar springs see how that looks for netting 3.0 front left for looks. Then I can go less spacers in back then I have now or same stock mopar springs and only spacers.

I would rather have springs then just spacers but I want it to look right/good.

if I do fronts only first and it looks good then I keep back 2 inch springs and front does have swaybar links.

if I really need bigger articulation I can throw on 35 tires and prob be ok otherwise I should be able to swing it on most trails.

I netted 3.75 front and 1.75 back from the 2 inch mopars.
