My car is basically stock at this time (only changes are the 15x7 cragars with 4.25 backspacking and 235/75/15 BFG AT). I wanted to get rid of the sag in the rear springs so went ahead and replaced the front coils, leaf springs, and shocks. The car is my daily driver and not for any rock crawling (maybe light trails or mud).

All of the following were purchased on Amazon:
-Dorman OEM Heavy Duty Leaf Springs (rear)
-Moog OEM Variable Rate Coil Springs (front)
-Monroe SensaTrac Shocks (front)
-Monroe SensaTrac Load Adjusting Shocks (rear)

After the above were put in, I noticed an increase in height over stock.

Using the hub lift measurement guideline, I measured just shy of 20 inches in the front and 20 inches in the back (from center hub to bottom of fender flare). Does this equate to a 2 inch lift?

I'm wondering if 31x10's on 15x8 soft 8s (4 inch backspacing) would fit without any rubbing. I'd like to fill the wheel well as much as possible without any rubbing.

Also is there a big difference in MPG between what I have now and upgrading to 30 or 31 tires?

My jeep has a 3" lift and I'm running 31x10.5 and I'm just barley making it. Back is fine but the front if I turn all the way and flex a couple of inches up then it rubs (just barley). I don't think your set up will work for 31x10 as far as gas mileage goes I haven't noticed a massive difference. Just take it easy on takeoff.

My recommendation is if you have a buddie with that size tire, throw it on your jeep and see if it will clear

You need different wheels for the first thing a 15x8" with 3.75-4" max of BS. I run the Cragar Soft Eights 15x8 with 3.75 BS and a 33x12:50x15" i have ran down to a 31x 10.5 on these you need the 8" width in the wheel so you can air the tire down some for off road use (better traction, smoother ride).


You would be better off returning what you have and just buying a full leaf/coil 3" lift from Rustys a matched set of the springs/coils. shocks (for a 3" lift) and all hardware needed u-bolts and all included. Not like what you bought (made in China) these are all made in NA and the full kit is only $438. The one thing you didn't have listed was a new track bar an Adj. one required to buy extra with this also required.


You can get by with 31x10:50x15 with a stock gear for a while I did till I decided what size tire I wanted to end up running (33 and 35's now for me and a 4.56 gear with lockers.


But............You must have the proper wheel for them not to rub and I would guess some trimming will be required also.
