Where did you get the sticker for the charge port door?

Hello all,

I recently got the mopar ‘2”’ lift and 37” BFG KO2’s installed on procomp 17x9 7069 series rims.

I am posting these pictures to help others make a decision as I would have appreciated the same during my research phase.

It is worth noting this is my first Jeep though I have reasonable mechanical experience from the past.

I’ll start with the normal flat ground photos:

I don’t have a spare tire carrier yet, it seems they are in short supply. The 37” spare does fit in the back but you will need to put the rear seats down.

Then I set the tires straight and lifted the front passenger tire using a forklift:

I neglected to get a front or offside photo at max lift but the tires will rub the trim at this point.

I am thinking of installing longer bump stops to prevent this or try heating and remolding the trim.

Then I set the tires at full lock to see how high I could lift it before the tire hits the bumper:

Hopefully this helps shed some light on what running 37s looks like and means.

In hindsight I should have measured the max heights and corresponding distance to bump stops.

Thank you guys, any advice you can give regarding improvements to this setup to prevent rubbing and maximize articulation would be appreciated.

Looking to see 37s and what lift you are running them with - with pics!

Learning that the factory height of 4xes differs from our non-4xe brethren, I am curious how things are shaping up.

I’m a “minimal lift” kind of guy aesthetically, just want enough for full clearance with 37s.

I really like the look with the 37s and a mopar lift. One question I have not seen answered was about how much affect there has been on Rubicon braking? If you go from stock 33s to 37" tires, are people changing anything in the braking?

Sorry if I disrupted the flow of this topic, but it does seem related.

Sierra Fan, do you mean "regenerative" braking? I'm on 37" Ridge Grapplers and have not noticed any real impact on regen. I'm on stock Rubicon 4:10 gearing and the vehicle is def more sluggish going forward, but while physics say the same must be true in reverse, but it's not noticeable. Braking is fine, steering is fine. Stock JK steering on 37's is suboptimal, hard to turn the wheel, I'm delighted that the JL, or at least the 4xe JL, appears to have much stronger steering power.

Not regenerative braking, just braking in general. With going to 37s, was wondering how hard you need to hammer on the brakes in an emergency stop. Did you change pad material or stay OEM. Good to hear that braking is fine. I've got a JLUR with the 3.6 and stock gearing. Just weighing the negative impacts of going up to 37s. I like the BFGoodrich KO2s so I'm considering those in the 37. They are lighter weight than most others.

I have not noticed any difference or at least anything significant enough to make me question doing anything about my breaks.

The keep stops quickly when I need it to.

One advantage of the 4xe in this respect over a conventional Jeep would be that a fair amount of daily breaking would be handled by the regenerative break and only using the friction breaks to actually stop the vehicle or for heavy breaking.

Removing your front bumper end caps will let you get more flex when the wheel is turned. Flex it out again and check bump clearances and make any adjustments as needed to eliminate rubbing. You can get bumpstop kits relatively cheap. If the rubbing isn’t bad you can try taking a heat gun to some of the areas rubbing on the inner fenders and see if you can massage them to fit.

Do you have any pics with the 35's on stock rims? I like the stock rims and prefer the tires not sticking out too far.
I don’t, sorry….just the 37’s on 20’s.

Your jeep looks great. I have a 4xe being delivered in 2 weeks. Trying to figure out all of the mods I want to get done. So far I have the Mopar 2" lift, 35 BFG KO2's, fox steering stabilizer, RC tailgate reinforcement and spare tire relocation. Deciding if I want to stay with stock rims or go aftermarket.

Your setup looks awesome? How have the 37's affected your electric range? Any rubbing at full articulation?

Thanks MSparks909,

The next day I removed the bumper tips - but I have not tried flexing again yet.

I hope to get some time soon to do this again, I was thinking of wrapping some rags around a large rubber mallet to make a smooth rounded… press to use with a heat gun and try remoulding the fenders a little.

I’ve not done that before so I wasn’t sure how much I could gain out of it.

I’ll post back here if I needed to add longer bump stops.

Since removing the bumper tips I did a bit of off roading and heard some rubbing but nothing serious at all and it only happened when dropping off of a larger rock.


The other time I got some scrapping was actually on one of the skid plates. I had to go over a large rock that was only about 2.5 ft long but with a decent height (great for high centering)… so when the front wheel dropped off the far side, the body was not high enough to clear the rock.

The 2” lift is… arguably not a 2” lift when installed on a rubicon. I feel if I had a genuine 2” of extra clearance then my skid plate probably wouldn’t have scraped the rock.

Here is mine on a teraflex st-1. 2” in the front and 1.5” in the rear. Bfg ko2 37 x 12.50 r17. I want to regear, but am on the fence between 4.56 and 4.88. However it not very noticeable that it has those tires on it. Tbh, I could probably have fit the tires with just the fender chop, I also have not really tested it out on the trail yet.
