Hi all ! First time ever I join and ask question online ? I am sorry I know this has been asked a lot but I read a lot and no result
Jeep Wrangler 2019 Sahara v6 automatic
I am not off road guy, I’m high way and city driving, my fav off road driving in desert and sand nothing crazy.

I’ve lift kit 3 mopar installer by dealer and upgraded fenders and inner fenders I’ve plenty of space so I added 37x12.5x17 bfGoodrich
no rubbing, driving I felt the same as 33 slightly heavier.

I don’t know what axle I’ve and / or what I should get for the driving style I’m after ?
I see 8th gear on highway At 55miles and 1300-1500 rpm with 30mpg on screen.

do I need axles ? Please use full description answer cause I’ve no experience in shortcuts my English not perfect ?

I’m looking at :
1- axles what sizes front and back
2- re gear ? I bought superchios flashcal do I use it before re gear ? Still didn’t use it.
3- differential covers front and back Afe ?
thank you, sorry it’s long post I’m drinking and bored and confused in middle of nowhere

Your not into off-roading so your axles are fine. Just need to regear to help out the rpm.

37’s are tall enough and provide enough ground clearance that you will not hit a curb in the parking lot. You don’t need diff covers.

I took it to dealership and they did the speedometer and balancing things out, it runs more smoothly and all good thank you ??
p.S: dealership charged 300$ and I can adjust anytime I want it’s like registered to my Jeep vin. All good
