94 Jeep yj with manual transmission 33s and 3.07 gears

Hey everyone, first time posting...I have a 94 yj with 5 speed 33s and 3.07 gears. I wanted to do some off roading at rausch and was curious if anyone has rode their yj with this similar set up and how it performed. I know it's not ideal but don't have the cash right now to do any major upgrades. I don't do any major rock crawling btw but like to have a good time. I used to use my 2014 jk but I recently got the yj and am real excited to see how she does.

Thanks
Tim

Not that great you really need 4.10's and even then without lockers you still only have 2wd. Lockers and gears should be done before lift and tires and 90% of people don't do it at all.

Yea unfortunately I got the Jeep already with a lift and tires and they didn't do the gears. 4.10 on highway is fine?

Here is most of the reply I just gave to another poster in a very similar situation..

If you don't do much interstate driving you'll probably be very happy w 4.10's.......

My YJ on 33's and 4:10 gears does great on highway i wouldn't want gearing any lower than 4:10's for 33's. The only time i have problems is with a strong headwind and there's not much you can do to make a YJ aerodynamic they just don't cut wind well. Keeping the jeep light helps a lot though so don't weight it down with heavy bumpers and spare tire carriers and body armor if you can help it.

I had 33's and stock gears for a while and life was miserable. It sucks not being able to use 5th gear and it sucks having to resort to low range offroad when you should be able to pull high range fine but your ring and pinions wont let you.

^^^ This, 100%

OP's Jeep sounds EXACTLY like mine. PO put big tires, body lift, suspension lift and a tire carrier on because it all looked cool, but didn't do anything about the gears.

I'm running 33x12.5 with stock D35/30, 3.07. I pretty much just don't go on the highway. When I take it out to the deer lease, I tow it behind my truck. 5th gear is a distant dream. Even in 4th at about 70 (don't k now for sure because speedo gear was never changed out), I'll lose speed going up a slight grade, and the Jeep struggles to even get to that speed.

It would be super duper awesome if I had the $$ to do an 8.8, and I'd put 4.10s in. And maybe some day I'll do that. But for now, I think I'm going to try to find a 4-cyl of the same era and get those axles.

I don't do a lot of wheeling, and no crawling. Unfortunately, it spends a lot of time on the pavement these days. And for around town at sub-60mph speeds, it's fine.

For what you're doing, it sounds like finding a set of axles from a 4-cyl YJ would be the best way to get a more usable drive ratio. Personally, 4.10 gears are too high for me (low numerically) for useful crawl speeds and torque multiplication. I am running 4.88 gears with 33" tires, a 4.0L and 5-speed and feel that this setup is about perfect. I can run highway speeds (75 mph out west) at ~3000 RPM, can maintain speeds up hills and inclines, can pass cars with ease, get respectable gas mileage, and have a good crawl speed in slow/technical areas.

Thanks everyone for your input...very help..I'll be looking into regearing definitely after this next off roading trip. I've never had it off road with what I got so I'm going to see how she does and regear afterwards when I save some money. Thanks again
