So, am new to the Jeep family. We have a beautiful 4xe now, and I am interested in lifting it. Suggestions for how much lift, tire size, etc. Also concerned what this does to a) gas mileage and b) operation of the electric mode. Does this cause issues? Are some programming adjustments required?

Thanks, Jeep Newbie

The only lift currently certified by Jeep is the mopar 2” 4xe lift. I have it on my Rubi 4xe and did not get 2” out of it. Electric mode is fine. I have38” tires and have experienced some rubbing. I really need the actual 2” or ideally more like 3.5” but I wheel a lot. Programming required for getting speedo to work with bigger tires. Gas is mileage is not just lift but whole package but yes it will be adversely effected to some degree. Enjoy!!!

I put 1" spacer in the front and 1.5" in the rear and although i could put 35" tires with no concern of rubbing, i have kept the stock tires to maximize range. Looks, rides and climbs awesome.

I’m relatively new to the off roading side of things as well. We got a Rubicon 4xe with the intent to build it up and take it out however stock it can do most anything given the know how and patience.
As for lifts AEV now has a 4xe 3 inch lift so with the Mopar you have the two choices. ZAutomotive Tazer Mini supports the 4xe and allows you to choose a tire size so your speedometer is accurate (among other cool things).
I emailed Teraflex about their lift and they’re 2-3 months out but perhaps worth the wait to have adjustable reservoir shocks so you can adjust the softness and stiffness of your ride. I want to do this to develop a “palate” for what the variance in stiffness feels like instead of getting a lift and just assuming it’s what I wanted or needed. As you load up your Jeep the additional weight requires stiffer suspension so you don’t go all wee levels wobble. The 4xe having and additional 600 or so lbs from standard requires a different setup than the gas and diesel JLU’s.
Something to consider is if you put larger tires on the axle, gear box and engine will have to work harder to rotate the additional mass. The Rubicon has axles and a gear ratio that should be able to handle 35”no problem but may start bogging with 37” tires.
All said we’re going to go up to 37” with a Teraflex 3.5 lift when it becomes available and swap out the gears if need be.
One of the early episodes S1E2 or 3 of Motortrends Dirt Everyday, Fred (the host) does a 2” lift on a sport and walks through the ins and out of what a lift entails. It’s a great show all the way around too. Hope this helps.
If you’re in Colorado I suggest going to talk to CJ at High Country 4x4.

Really appreciate the information. I’m in So Cal. I need to search out contacts here. Thanks much. Enjoy the Jeep.

Hey I'm in So Cal as well (San Fernando Valley), let me know if you come across any, I will do as well!

Are you happy with the addtl lift? This increase the stock lift correct.

If you have the mopar 2 inch lift and 37’s does anyone know whether you need to reprogram the speedometer or not?

Lift doesn't matter. The change in tire size will put your speedo (and odometer) off somewhere in the 12-15% range, and your Jeep will be using that information for shifting.

How can you make the speedometer accurate then??????

Tazer Jl Mini
JScan
Dealer Flash

Maybe the AEV Procal, RC Calibrator, Superchips Calibrator. (I assume these will all work, just don't want to tell you positively without confirmation)
