Some of you say that, and I suppose it is "DO-able", but definitely not ideal. I was initially going to go 30's, but I got a great deal on 31" Dueler AT 693's already mounted on wheels. Drove it for a bit with stock gears, it SUCKED. And mpg took a hit. Swapped in a C8.25 with 4.10s, mileage went back up and I feel like it goes somewhere now.
I think there are some older older pics of my xj w/ 3" lift and 235's. I do not think it looks that silly.

If I had to do it again, I would have swapped the 4.10s first.
There should also be some semi-recent pics of my heep on 31's with 3"

 

What about your rpms on the highway with those 4.10s and 31??

 

i have stock d35 diffs and an 8" rough country lift and 35's and have no problem wheeling and have plenty of pep, i also get 22 mpg

 

70mph approx 2300
IS your MPG corrected and GPS verified?

 

3" rough country lift with full leaf packs. hard to tell that it's parked on slight incline but it sits level.. turned out better than i thought.


please excuse the plasti-dip paint job, that's only the first coat.

 

yes it is, i have done plenty of work to help it, namely 45 psi in my tires, 703 injectors, high flow cat, dynomax super turbo cat back system, air intake, no mechanical fan, no ac compressor, not to mention i coast all the time lol

 

What about going to a 3.73 from 3.55 on the C8.25? If I'm going to regear I would want near stock performance. I know this subject had gone back and forth a million times but if I don't have to regear to run 31s and still maintain good off road performance I won't.


Oh and do I have to drop the transfer case being 2wd? lol jk jk

 

Mmmmm long arms! Sick Jeep man!!!
Seriously having a hard time beleiving 22mpg solid with that setup. Not on you but the XJ's accuracy.
I've driven a new XJ on 33s with 3.55s and pep is not in it's vocabulary.
You may be one of the lucky few.

I suppose if you're on flat ground all the time and slooooowwwly accelerate, then once it's up to speed those 35"s put a lot of distance to the ground with minimal load and high geared axles then maybe 22 but I would think the rotational mass of the 35s would inhibit it on rockier trails.
You're not factory geared 4:10 possibly?
Hope you're carrying spare shafts lol. That D35's probably begging for death, poor thing
I've known a few guys who've run 35s with stock gears but they only wheeled them never highway and they had 8.25s not a D35.


Mine on 3" BDS full spring lift and 31s. Want to go bigger but it's my only ride lol.
The rear is about 2 inches lower than normal in this pic because it had a few hundred pounds of river rock in it (breaking in the lift lol). It normally sits where a 4" should a little higher than the front is in this pic.

 

Just to warn you 33 inch tire's wont fit on a 3 or 3.5 inch lift without alot of cutting. I'd stick with your 31's they look fine with what you have.

 

No you don't. you can run stock gearing up to 33 inch and be fine. But at 33 inch you really start to notice the gearing.

 

So wait till you get your new tire's and do the lift and tire's together.

 

3" Zone lift with 31" BFG AT KO's

 

I would but I'm impatient lol

 

I found a complete Rusty's Offroad 3" lift kit in a Pick-A-Part a few weeks back. Had 3" lift coils, 3.5 leaf springs, tubular upper and lower control arms and shocks. Great deal. Purchased some Treadwright Guard Dog M/T retreads in 31x10.5x15. I had to get some 1.5" spacers to use with the stock offset wheel so the tires don't rub on the lower control arms when turning sharp. But other than that, it works great.
