1988 Jeep YJ modification ?'s

- Can I put 4.88 gears in a stock rear end?
- What combination of body and suspension lift will give me the clearance for 35" tires?

Yes you can put 4.88 gears in a stock rear end, that is the deepest gear set that will fit in the stock housings.

As far as clearance for 35" tires...It depends on what you want to do with it...Is it a street machine, mall crawler? Just mild wheeling that doesn't require actual 35" tires? Or is it a "hardcore" wheeler that does it all?

I have an 87 with a total of 8.5" of lift and 35" tires and if I flex it out, they still rub. To answer your question...if you want a hardcore wheeler...I would go with a spring over axle lift which gives you around 5-6 inches depending on the condition of the springs. And then add some TJ flares which require the fenderwell openings to be trimmed. Then you can clear the 35" tires.

^^ what he said. Most of us don't need 35's. But that doesn't mean we don't want them. I Think technically a 6 " suspension lift will let you clear 35's. But you probably won't have much, or any, room to flex. It would likely take 6"+ of lift plus fender trimming or new fenders all together to fit 35's And be driveable.

Not to mention that most everyone on hear says putting 35's or larger on the Dana 35 is turning it into a disaster waiting to happen. There are some people that have/still run 35's or maybe even 37's without major issues for some time. But I don't think I've heard of anyone that didn't upgrade quickly. The ford 8.8, Dana 44 and Dana 60 are common candidates.

yeah I would have to say im neither due to the fact that I have had to do a lot of work to it since recently buying my jeep. I have been considering upgrading to the ford or dana but was trying to see if there was other options before I mess more stuff up. appreciate the help
