Hi, we are completely new to owning a Jeep. We just purchased a new 24' Willy's 4 door with the 3.6L and the dealer installed a 2" Mopar lift with Fox shocks and steering stabalizer along with 35" tires. We love it!
I do have a few questions
1. The front end sits about an inch higher than the rear, I measured from the top of each tire to the bottom of the fender. Is this normal and any way to adjust it?
2. The speedometer is off, it reads 3mph slower than you are actually going at 40mph and about 5mph slower at 75mph. I'm assuming this is a simple programming change for the tires that the dealer can do and should've done to begin with?
3. If the dealer didn't change programming for the 35" tires, is there any other programming that should be done when adding the lift and tires? Transmision shift points or anything?

Thank you!
Get yourself a JL Tazer mini...it's the best first mod you can do. It does so much more than I can even list here. One of the most nifty is using the locker in 2wd among many other things.

I have one more question; Is there a way to change the tire pressure sensor setting so it doesn't come on when aired down? I aired down to 18psi and the low tire pressure warning was up constantly, not a huge issue just a little irritating.
You're aired down and the warning is completely valid / appropriate. If you disabled it then it becomes fairly pointless. I'm guessing it really bothers you.

In theory a Tazer could turn it off while we're in 4lo or whatever, but it currently doesn't have that functionality.

Even using a Tazer the lowest you can set it at is 25 so any time you are low off roading itll be on
Same with JSCAN. It's a limitation restriction in the jeep firmware. If it bothers the OP a lot, a little square of black tape over the light during aired down operation, should ease the subconscious to red warning lights.

Shouldn't the dealer have dealt with calibration when doing that install?
Old post, but this dealer response is from October of 22

Saved in case they ever bitch, blame, or deny warranty due to the Tazer.

The dealer installed the 35s, initially refused to calibrate the Jeep to deal with them, then apparently eventually gave in and did it.

Maybe it has changed in two years, but that’s what I got when recalibration was requested 🤷🏼‍♂️
Request due to “Service 4WD” — input shaft speed, wheel speed. Jeep couldn’t fix it and aftermarket was their “fix” amazing.

To make sure the dealership has no excuses regarding his warranty, I completely understand the OP not wanting to mess with a Tazer. I returned a tazer bc I did not want to risk it by forgetting to take it out. The dealership should fix this.
