What size lift do I have?
I bought an 02 TJ and I am trying to figure out what size lift I have. I was told it was 2" but I don't know of a 2" coil kit. I would like a couple measurements from a stock TJ if possible. (I looked around on here and couldnt find them, maybe someone could add them to the "Measurements" section).
I am looking for stock height to the bottom of the rocker and center of the wheel hub to the bottom of the fender flare in both front and back.
What I do know about my Jeep:
- It has 31's on it which I put on.
- The springs aren't marked but are coated with a medium/dark gray coating.
- Out of all of the shocks, one sticker is readable and it says Sensa-Trac which come to find out is from Monroe.
- It doesn't look like there is a drop pitman
- There is no body lift.
- I added 3/4 spacers up front to help compensate for the bumper/winch combo.
- If it matters, it is a 4.0, 5 spd with a 100lb Trail Ready bumper and a 90lb winch.
Here is a picture of my rig as it sits now. If anyone knows of this older kit from 'back in the day' (back as far as 2002) let me know. Also if you could take a couple of quick measurements, that would be awesome. Thanks guys.

Ha, never thought of measuring the springs...Thanks! I will try that..
I suppose measurements could fluctuate depending on the age of the springs and things like aftermarket bumpers, tire carriers, automatic transmissions vs. standards and 4cyl vs. 6cyl etc.....
Thanks again...if anyone might know the company that made these gray coated springs, that would be helpful. I am looking to get new shocks and want to be sure I get the right length based on the manufacturers specs.

Looks like 2" to me. What kind of shocks are on it? That could give some indication as to the spring brand. Most springs are dark gray so that really doesn't tell you much. I know Rusty's makes a 2" lift, and I think BDS might as well.

The shocks are Monroe Sensa-Trac which look 'original' to the lift. They are pretty rusted on the outside but still hold pressure...I didn't know/think that Monroe would make a shock longer than stock applications.

Dont have a tj but if I was to measure springs, I would lift the jeep up until the spring is not compressed at all and take the mearsurement. Should be close enough to tell what it is.

According to the link in the second post, these measurements are of TJ at ride height:
"Below are the approximate heights of various TJ coil springs when sitting at ride height with the weight of the Jeep on them. The measurements are from the very top of the spring where it meets the isolator or coil bucket to the very bottom of the spring (again where it meets the isolator or coil mount)."

Monroe definitely makes longer shocks (Skyjacker/whoever else Hydros/Nitoros), but I didnt think they sold them under their own brands. AFAIK, Sensa-Trac's were factory replacement shocks.
I think your best bet would be simply measuring the springs. Taking them out of the Jeep would obviously be ideal, but probably unnecessary. The winch/bumper will definitely compress the springs more (around/up to an inch usually).
As far as determining a brand, that will be essentially impossible without some sort of numbers/tags/markings from the springs.

Doesn't matter. Measure the spring perch to spring perch distance, compare to stock, and buy whatever shocks you like for that much lift.

That tells you precisely nothing.
The length of an uncompressed spring doesn't equal how much lift it will provide, some springs (for example) are stiffer than others and won't compress as much under the weight of the jeep.

No, see above. Same for added weight accessories.
You want to order shocks to fit the amount of ACTUAL lift you actually have - if it's squatted down with extra weight and the net effective lift is less, the shocks need to fit that actual height.
(Here's what I mean: Lets say you install a 4" lift. Then you added a bunch of heavy stuff and it squatted both ends down so now you only have 2" of Actual lift height. If you buy 4" lift shocks, they'll be too long. You'd need shocks for 2" lift since that's what you actually have.)

Is anyone able to take a couple of measurements for me?
Still looking for: I am looking for stock height to the bottom of the rocker and center of the wheel hub to the bottom of the fender flare in both front and back.

Are you still trying to determine the amount of lift on your TJ? See post #7. When you measure the springs, include the spacers you have installed in the measurement. This will give you the amount of lift you have. All other measurements are pretty much meaningless.

Well yeah, because of my 'lift' and 31's, I am trying to figure out how much taller my Jeep is overall compared to stock. Just because I have a 2" lift doesn't mean I have a full 2" when you factor in spring sag, bumpers winch etc. I just want to know how much higher i am actually sitting vs. stock. What size are stock tires (non Rubicon), 27" or 28" inches?

Sag won't make that much difference, and honestly, it doesn't look lifted to me in that pic, at all. Just measure the springs for goodness sake. It takes one minute and you'll know.....

The TJ came with 215/75/15, 225/75/15 or 30x9.5x15 tires.
It really doesn't matter about added weight, spring sag, etc. Just measure the springs + spacers and that's how much lift you have.
