There was never any question for Cindy and I that JET Li, our brand new 2018 Jeep JL Wrangler Rubicon Unlimited, would be running a set of 37" tires and much sooner than later. What was in question was, how would we get there? How much lift would it take to clear them and could it be done with wheels that have a bigger amount of back spacing especially now that JL Rubicons come with 68" wide axles? In the end, we decided to run 37x13.50 Cooper STT Pros mounted on KMC XD231 beadlock wheels that have 4.75" of back spacing and try to make it all work with an EVO 2.5" Stage 4 Budget Boost, complete with all 8 adjustable control arms.

Soon after getting everything installed, an initial test drive showed us that this setup worked great or at least, around town anyway. The 2.5" coil spacer lift provided plenty of room to clear the 37" tires and we saw no rubbing at a full lock, in either direction and this in spite of the tires being 13.50 wide and mounted on wheels with 4.75" of back spacing. So, the real question now was, how would this setup do off road? Fortunately, for us, a good flex test was just down the street from us and the following are pics of what we found.

While ramping a Jeep or lifting it from one corner with a forklift can give you an idea of things, the best way to see just how much flex it really has is to get it twisted up. The opposing flex will force the axles to mash into the bump stops and drop the opposite side down to a full droop. Unfortunately for us, we were already hearing a good amount of rubbing well before we could work our way up into our testing obstacle but, here we went anyway. For our first test - driver side front up and turned to the left.

As you can see here, the front jounce stop or bump stop is fully compressed.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195550-4a156c24-me.jpg

In spite of how this pic may look, there is no rubbing of the tire on the driver side fender liner, coil perch, frame rail or other wise that we could see on the driver side and with the wheels turned to the left.

https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195538-c0da2f0f-me.jpg

At a full droop, the passenger side coil is still seated properly.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195602-ba37827c-me.jpg

Brake and ABS lines all seem to be good.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195607-d1417c22-me.jpg

Turning to the right to check for any rubbing or clearance issues.

https://www.wayalife.com/photos/upload/2018/03/14/20180314131219-496569f7.jpg

Here you can see that the tires clear the front bumper and grill.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195703-f1e443d5-me.jpg

Amazingly, the 13.50 wide Cooper STT Pros tuck up and under the fender as well but then, a lot of this has to do with the 4.75" of back spacing that the KMC XD231's have.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195718-ccc7e9ca-me.jpg

View from the back of the driver side front wheel well to show the fully compressed bump stop and shock.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195726-86c5ee2b-me.jpg

With the wheels turned, you can get a better look at the passenger side front coil bend.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195646-56fb8530-me.jpg

Moving to the back of our JL Wrangler to get a better look at things.
https://www.wayalife.com/photos/upload/2018/03/14/20180314131145-376f10af.jpg

With the driver side rear tire drooped out, we could see where it had be rubbing a bit on the lower fender liner that covers the bumper.
https://www.wayalife.com/photos/upload/2018/03/14/20180314131015-6fd44e04.jpg

On the passenger size, we could see that the tire was making full contact with the lower fender liner that covers the bumper.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195630-88eefbc2-me.jpg

The bigger problem we found was that the lip of the main fender liner was catching on the tire lugs and getting pulled up. In fact, you can see that a push tab had already gotten pulled out. This was clearly the source of most of what we were hearing.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195627-a771f951-me.jpg

Looking toward the front of the rear wheel well, we saw that things were clearing well. Certainly, no issues with the pinch seam or rock slider like you would have seen on a JK.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195637-a44ecd74-me.jpg

Moving forward through the obstacle so that we can switch our twist.
https://www.wayalife.com/photos/upload/2018/03/14/20180314131239-eedb5916.jpg

Verifying that we have full stuff by making sure that the bump stop is fully mashed.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195829-127ba622-me.jpg

https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195837-91cebb9c-me.jpg

It's close but the back of the passenger side front tire just misses the fender liner when turning to the right.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195821-fd8207ce-me.jpg

https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195817-30a30832-me.jpg

Turning about half way back to the left, the tread just kisses the fender trim as you can see here. Being that we are at a full stuff, this shouldn't be a problem.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195814-eae3de53-me.jpg

At a full stuff and lock to the left, everything clears and you can see where the tread just kissed the fender trim.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195751-0a7e9852-me.jpg

Toward the front of the fender, you can see how the tire is just making contact with it here.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195742-df47772a-me.jpg

And toward the very front as well.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195735-0dff8db5-me.jpg

Like the driver side, the tire clears the grill just fine.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195729-c23315b7-me.jpg

Pushing all the way through the obstacle.

https://www.wayalife.com/photos/upload/2018/03/14/20180314131317-28a8c899.jpg

Back on level ground, you can see where the passenger side front tire was brushing up against the fender liner.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314200000-9dffbeb8-me.jpg

Looking back at the passenger side rear wheel well, you can see how mangled the fender liner got.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195944-816a3a4a-me.jpg

The driver side rear fender liner fared better but I think it'll just be a matter of time before it gets mangled up too.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195948-7cc5c3a1-me.jpg

And that concludes our first flex test running 37x13.50 Cooper STT Pros mounted on KMC XD231's and all sitting on top of an EVO 2.5" Stage 4 Budget Boost. As you can see, we'll need to head back to the shop and make some modifications. :cool:

FIX for the FENDER LINER
Back at the shop and ready to get our fender rub fixed, I started out by removing the lower liner that covers the bumper. On the driver side rear wheel well, this is where we were seeing most of our rubbing and an 8mm socket and 3 screws removed later, this is what we were looking at.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195334-77c4eb23-me.jpg

Again, using an 8mm socket to remove 3 more screws, this is what the bumper looks like without it's plastic end cap.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195355-79e10a01-me.jpg

Using a 16mm socket, I then removed the lower liner bracket with the hope that would clean the look of things a bit. Here's a few shots of what the rear end looks like with just the steel bumper installed.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195419-b4de2cf2-me.jpg

https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195423-451d66a0-me.jpg

Moving over to the fender liner itself, I used a heat gun to help me reshape the embossing and concave it out of the way.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195435-1311880f-me.jpg

https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195439-a04541a8-me.jpg

That ought to do it!
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195451-ffa589b1-me.jpg

Not super thrilled with how the bumper was looking, Cindy and I decided to reinstall just the plastic end cap.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195515-93119919-me.jpg

https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195503-5dedd64f-me.jpg

As a reminder, this is what the passenger side rear fender liner looked like after our flex test.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195944-816a3a4a-me.jpg

And, with the help of a heat gun and a bit of reshaping, this is what it looks like now.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195523-82bf22fc-me.jpg

More of a profile view to show much I was able to push the embossed feature of the fender liner out of the way.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314195527-ee51d7e4-me.jpg

With that, we should be good to go. Just gotta take JET Li back out on the same obstacle and see if the fix did the trick. :cool:

FLEX TEST 2 : Did the Fender Liner Fix Work?
The following morning, Cindy and I headed back down the street to see if my fender liner fix did the trick. As you can see here, we worked our way up the same obstacle and if anything, went high enough to hang a tire.

So far so good. Time to twist up the other way.

Just because I thought it's worth noting, what you see here is our Cooper STT Pro squashing out and planting its tread firmly on the rock face below with 29 psi as verified by our TPMS.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314201432-27b0614d-me.jpg

https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314201446-7ac08740-me.jpg

So.... how'd the fender liner fix do you might be asking? Well, here's a shot of the driver side rear and as you can see, the fix worked out great. The tire came close but cleared it without any problems.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314201601-659b17df-me.jpg

https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314201508-504260a3-me.jpg

Same is true of the passenger side. As you can see here, it got close but the tire totally cleared.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314201500-f5dbb095-me.jpg

Not a mark can be seen, felt or found on the fender liner.
https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314201548-7cfa3cf7-me.jpg

https://www.wayalife.com/photos/_data/i/upload/2018/03/14/20180314201552-d4ab398b-me.jpg

And there you have it, no more rubbing or none that really matter anyway. Clearly, 37x13.50's mounted on wheels with 4.75" of back spacing can be run with just 2.5" of lift so long as it comes with the right amount of bump stop extensions and your rear fender liners are modified. I hope you found the information on this thread to be helpful. Please let me know if you have any questions. :cool:

Oh, removing the rear bumper and running D-rings are high on my list. Not so sure I care for a fascia though. As far as fenders go, there will most likely be a day when we remove/trim the trim but for now, we like how things look and hope to keep it that way for a while. :)


Thatís awesome only 2.5 lift to clear 37ís.

Crazy ain't it - we LOVE it :yup:


Great FLEX!!!!

Kinda funny that it's the same amount as stock but it does look bigger with the bigger tires :crazyeyes:

Maybe no rubbing with a 3" lift. Even with the 2.5" lift the rubbing is minor and easily remedied. When my JL arrives I am going with the 2.5 or 3" spacer lift and 37" tires, just need to decide on tires and wheels. thanks for the pictures, really helps to see what is really going on with the suspension.

I was just explaining to my wife this morning that there were many improvements to the JL compared to the JK. I have been without a Jeep for going on fifteen months now and really getting the itch to get another one. A JL sounds like the ticket now. I have been wondering what it would take to get a JL to ride as good as my JK with the enforcer with EVO spec. Kings.

[Please let me know if you have any questions. :cool:

Outstanding and very helpful information. Our JLUR is on order and I'm convinced this is the wheel tire combo for us. We have gone through two sets of STT Pro's and that's a no brainer. Fantastic Tires (ours were 35 x 12.50 x 15s.

My Question for you is (and I also watched your video when you mounted them) What about balancing this set-up. Did you computer balance, and if so how difficult was it? Thanks in advance.

EDIT Also how did the gearing feel with the 37s, I had 356s with our JKUR and it was perfect. Auto transmission in both cases here....

Maybe no rubbing with a different 37. These Coopers measure on the tall side for a 37. If you were to run something like a BFG and on the same back spacing, you might clear altogether. :yup:


Great write up! Great explanation of your tweaks and adjustments.

Thanks, glad to hear this post was informative :)

You need to test drive one. I think you'd be sold.

Gotta love how a budget boost would of had you running on 35's on the JK and now 37's on a JL :crazyeyes:

Not all tires require balancing and so far, the ones that I just installed don't seem to need it. If in the future they start to feel out of round, I'll have my local Costco balance them with tape on weights.

Regarding gears, our Rubicon came with 4.10's. Paired with the new 8-speed auto, I haven't felt much of a power loss. When gears become available, I may or may not upgrade.

Honestly, so far so good. I'll need to do a lot more driving to know for sure but so far, the new 8-speed auto is doing a great job of pushing them along.

Way to go. I like the JL but I love my JKU and have way too much money in it to sell and start over. Good luck and keep up the good work.

I just ordered so much stuff for my JKU, but now I want a LJU. Seems like everything I'm buying for my JK comes stock on the Rubi JL. Maybe I'll get one next year and use it for my daily. So jealous.

Looks great! It'll be interesting to see how the stock axles and diff locks hold up while running 37s.

Great job on the write up and pics! Like others have said, it makes me want to get a JL now... must resist... It will be great to see how this evolves and how the stock components withstand the beatings you will give it.

Although I think you made an error or were joking by calling it a "budget boost", I am interested in seeing someone just run 35's on a stock JL no lift and see how it handles.

Thanks again for making us jealous!

Well done as always!!!!! Over all how does it feel on 37's? Also were there any lights or electronics acting up after the lift went in?

Way to go to make them 37s compatible on a JL with a small lift. Something always have to give and massaging the inner fenders worked out great.

Oh, there really is no need to get a JL over a nicely built JKU. Be happy with what you've got and use it. :thumb:

Thanks and you know we will :cool:

LOL!! Have fun with what you've got. The JL will be around for a while.

Well, we'll find out and let you know :crazyeyes:

LOL!! With all that we got, it is a stretch to call it a "budget" but it was just a "boost". Without the control arms, it is closer to being affordable. :cool:

No lights, no problems. Suspension and handling feels the same. Going from AT's to MT's is noticeable in terms of lug thumping and the load range E of them is certainly noticeable as well but then, none of this is a surprise to us.

Thanks. Always nice to know you can make something like this work with as little lift as possible. :yup:

Love the detailed photos of the clearance issues. Great stuff. I was wondering about the JL driveshafts. I have an issue on my JK where the front shaft rubs on the cross member at full droop. I was wondering if the JL will need new driveshafts in your configuration. Have you had time to check how they look?

The exhaust cross over has been redesigned and transmission skid bar moved out of the way to no longer be a problem with the front drive shaft. At least, they won't cause the slip shaft boot to tear. That being said, a 3" lift or more will still put the output shaft CV boot in a constant state of pinch. This WILL fail sooner than later.

Iím curious if or when the temp warms up if the JLU will go into limp mode with the 37s and stock gearing. But it sure looks good.

Shouldn't. Certainly, it hasn't happened for us anyway. We've had our speed re-calibrated at the dealership too.

It is very cool that it is so easy to make 37`s work.

However, where you live rust is no problem but for me with a lot of salt in the winters rust is a problem. When taking away those plastic pices the body is exposed to all the dirt and gravel that the tyres will throw up and in the end it will chip the paint and expose the metall.

Of course I do understand that it is proberly a fix to protect it in some way, maybee with some other "shields" that take less space.

Anyway, looks good!

LOL!! Wanna push the factory axles for a while and see how long they'll last but, hoping to get on 40's before the end of the year. :crazyeyes:

Thanks! It is nice to live where we do where we don't have to worry about things like salt. I'm sure I could have gotten more creative with the heat gun if needed though. :crazyeyes:
