Calibration after 37s? What else?

[Mikeyut3]

Have JLUR with mopar 2” lift. Going to 37s (Bfgs) this weekend. Do I need to re-calibrate and how easy/hard is this? Anything else I need to do to do this right? Thx!

Well the tires may not require as high of psi as stock. The tazer is nice especially with the rubicon. Can turn off auto start/stop, lower tpms threshold, sway kill is nice and many other functions. It also sets your tire height and gets speedometer correct.
Your axles may end up shifted side to side, which can be corrected with an adjustable front track bar and rear track bar bracket. It may feel just fine and not shift much, but acceptable shift is up to you. I have the mopar lift with corrections and running 37s and very happy with it.

17x9+12 offset. 37x12.5 mastercraft mxt tires. Use it too.

Amazing. Back to the calibration. Is tazer best and do i need to buy it or can someone who has one just “flash” me? I know there is a lite versus regular. And is there any advantage to owning it or keeping it plugged in?

Personally with the rubicon I would get the full for around $300 I believe. I can’t remember exactly. I’ll post a comparison shot here for you to see. If you off road much the sway kill function allows you to disconnect sway bar in 2wd and at any speeds. Factory is in 4wd only and only up to 18mph. Then when you run larger tires your psi will be around 30 vs stock at 37 so may have tpms light on all the time. Tazer allows you to change the light threshold to 25 or whatever you desire so your light isn’t always on. Also does a lot more, but those are the main ones I use along with start/stop kill. The light does some just have to see if you’d use enough of the extra ones on the full/mini.

You’d have to own it as well as it vin locks.

Nice pics...how many bumpstops are you running and how much do your tires rub wheelin when flexed up and turning?

Just the bump stops that came with the mopar lift. Think they are about 2 inches front and back. Can measure them if you want. Minor rub in the rear inner fenders and if I have passengers it will rub a little more but overall pretty minor. None on the front that I’ve noticed at all. I am putting motobilt inner fenders in front and rear later today or Thursday which may help a little with the rear rub. We will see. Like I say, it’s real minor.

Nice...I installed motobilt rear liners and artec knockoff front liners a few weeks ago and like them. I used a nutsert on the driver side due to access. I'm also running 2" bumpstops and have 17x8.5 wheels 4.75 backspacing(0 offset) and 37s rub the front inner liners a bit when flexing up and turning a decent amount. I imagine yours would rub a little more with +12 offset wheels...think a backpacing of 4.25 or less would clear 37s in front at full stuff and full lock.

It tucks up under the flare so I will let you know. Haven’t had any rubs in the front though so we will see after inner fender install.
