Before I make a recommendation, what is you differential ratio? What is your intended use for your CJ? What wheel size do you have now and do you know the backspacing?

My jeep is a 4" superlift kit and a 1" body lift. It has 33x12.5 on 10" wheels. When flexed 35" tires would rub on mine without some rear wheelwell cutting.

yea, 4" aint really going to give you room for 35" tires.
I have 6" lift on mine, and had to cut every corner to minimize the rubbing. You might wanna stick with 33" tires for now.

Differential ratio = no idea, I think stock ratio. I bought it few months ago and haven't opened the differential cover yet.
Intention = well normal onroad driving and I think maybe 7 to 8 times a year offroading.
The current wheel size that I have is 31" and backspacing I haven't checked it yet.

stock gears in a 85 will most likely be 2:73's, that AMC 258 i6 / 4.2l will be having a hard time pulling 33's. I see a gear change in your future.
Exactly!! And Id recomend some sheetmetal trimming for 35s. Maybe a 1 in. body lift also.

So if I have 331 gearsstock gears in a 85 will most likely be 2:73's, that AMC 258 i6 / 4.2l will be having a hard time pulling 33's. I see a gear change in your future.
I can handle 33's no problem???

HOW SO ?
Acceleration will be slow and uphill will be difficult , more downshifting. Id reccomend 4.10s for 33s

A bit sluggish with the 33" tires. I have run 33's with a 3.54 ratio and they were OK but 31's are my preference on the road.
Once you get into 4 wheel low you can push just about anything but you may find getting on the expressway a bit of a challenge.

i'm pretty happy with 4" lift and 33s on mine its factory 2.73s, T-176 , AMC 258 i6 / 4.2l , it handles 33s ok. i run it up the interstate at 65-70mph no problems. I still want to regear later for a little more power, but i think it'll do fine till you can regear it.

Hi. Most 35" tires will work with a 4" lift. Some tires do run larger and those ones will not. Larger tires look great but offroad there isn't much flex there, due to rubbing on the wheel wells. Those bigger tires won't turn as easy on the road and with a straight 6cyl your going to be low on Horsepower. 33" tires better flex offroad and onroad handling. If your running a model 20 rear axle these smaller tires are less likely to snap. You should get 1pc axles for it or upgrade the hole front end/rearend. Also go lower gears. Good luck do your research!

4" lift with 33's and some fender trimming (for no reason I might add)
...and with 36's, same amount of lift and very little rubbing.

If you're just cruising the island, either are fine.
For moderate wheeling 33's are fine, even if you are auto Transmission you should get most of the speed you will want to be at safely on larger tires. You may eventually break an axle
, at that time you upgrade to one piece, use what you have for now and build as you break, eventually lock so you don't have to work so hard. When ready you can get one piece hardened steel for 225-250 (crown) or alloys brands for about 400 ++.
If you go 35 and do any decent or flex type wheeling you will rub, especially if you disconnect sway bars. You will also end up breaking axles and some u joints. If you are geared stock R & P, you will end up spinning those big tires and hopping. This can typically tear up u joints, yokes, axles and twists driveshafts.
If you are into crawling, take your time in tough spots and use a spotter.You may eventually either want to regear or go 4 to 1 on your transfer to slow things down. You may want bigger axles. It never ends, but is great fun!

I have run 33s with 3:55 gears rpms were around 4500 at 40mph dogging down hwy 4:11s would be choice
Are you sure your statement is correct? 4500rpms at 40mph? I think 2500 rpms at 65mph would be closer to truth. That is were my jeep is at with a 4 speed.
I personally think 33's are the best overall choice for a street driven/part time wheeling Jeep CJ. For me the best gearing comprimise are the 4.10's to handle decent slower wheeling and still retain a normal highway capable vehicle. Of course that is just my opinion.
