I shall throw in my 2 cents. With a decent 2.5 and 4.88's you will be fine as a DD. You def not gonna love the love the gas mileage but I have been running 35/12.50/15 mickey Thompson baja claw ttc radials for quite some time now with 4.88's. I can see 75-80 miles an hour no problem.

This is also with a 95 2.5 with 80k miles. It's not speed demon by any means. On that note I should tell you that I'm upgrading to 5.3 vortec with a NV3550, don't let that discourage you though. This setup will work perfectly fine, for sure get you an 8.8 and gear upgrade.

Here's a pic of my 95 yj unfinished but with 35's and gear upgrade ect ect

Mine's a work in progress, as I said. I don't do highways luckily, so the slower top end doesn't concern me.

After the LQ4/9, it'll be just fine.

Though, depending on how many more terms the president gets, I may be looking at a diesel.

I have a fresh 2.5 that is well maintained and I currently run 35" tires with 4.88 gears. Even 33's are bad with 4.10 gears and I would prefer a little higher than 5.13 but 4.88 is great. I can hit 80+mph without wind.

It isn't great as a commuter car. My gas mileage has never been good even with 31s and 4.10 gears.

My AX5 has been holding up too. I change the oil in it every other time I change the engine oil.

I have even run 37" tires with my 2.5 liter at times. 37's are really pushing it I admit.

I made the trip from OKC to Bridgeport, Texas last month. I cruised at ~80mph there and 65mph back. It was around 380 miles round trip. (I even wheeled some wet class 3 and 5 stuff)

Take care of your engine, don't add stuff that de-tunes it and get proper gears. You'll be fine.
I agree with you. I've had 35s on my 2.5 for 10 years...it's fine.

Ive run the AX-5 on my rig for at least 10years as well. I wheel pretty hard. I also daily drove the rig for 6+ years. Are there better transmissions yes, but its not the grenade some would have you believe. Ive killed a coulple 9" Fords, some chromo shafts on the 30, a TC case, but never had the first trouble with the AX-5. Also could cruise 60 to 65 all day every day with the 2.5 and 4.56 gears.. It got the job done. No rocket, but it did its job. Offroad it is a non issue. will go anywhere any other similarly equipped Jeep will go. Period.

Your limited slip differential sucks.
