I recently purchased my second Yj. It's a 95 sahara 4.0 5 speed. I am tired of gear ratio problems with bigger tires. Is it an option to get 4.10s out of a 4 cylinder and bolt them up to my sahara? It seems like a cheap easy option rather than an 8.8 swap or re-gearing my currents axles. Are there any problems i would encounter? Thanks
However, depending on size of tire, it may not be a great idea to bolt another d35 in the rear. You'll get mixed opinions here, I fall on the side of thinking its not worth it to put time or money into your current or another d35.
as long as you dont go crazy wild when you wheel or have a lead foot it will be fine unless your gunning bigger than 35's get some chromoly shafts and call it a day it will end well unless your hard on it. its also an easy swap compared to say an 8.8

What year axles are you going to swap in?
There is a difference in axles by year. The brakes are different size and the brake lines are different on the earlier YJ years. They changed them in mid 1990. The discs are different too not that that matters, but if it is an axle out of an earlier YJ make sure to get the brake lines with it.
Experience. I put a '95 d-30 in my '88 YJ. Fortunately I gave my old axles to my son for his '90 YJ and we just swapped brake lines.
Betcha' wish your girlfriend was as dirty as my Jeep!

If you're going to regear anyway, taking 35's into account, my personal opinion is 4.56's for a DD, 4.88's for a trail rig.
4.11's will get you back close to a 3.07 / 28" tire ratio, but with the added weight of the tires, plus extra drag of the aerodynamic brick being higher in the air, I'd err on the lower (numerically) set of gears. This also takes into account my view that 3.07s are weak for a stock setup to begin with (which is why I believe TJ's had a 3.73 option in the Sports).
That said, if you're just trying to do this on the cheap, you could slap a 4cyl D30 front in with a 4.10 ratio 8.8 and that would be a nice budget combo where you can save a grand by not having to regear.
Thanks again. Last question, is the stock ratio on a 95 4.0 5 speed always 3.07. I've seen people say there was a 3.55 ratio on the manual too.
From the FAQ
What gears do I have in my Jeep?
I4 Automatic - 3.73:1
I4 Standard - 4.10:1
I6 Automatic - 3.54:1 (normally)
I6 Standard - 3.07:1, 3.54:1 or 3.73:1 - must verify with the tag on the axle or by pulling the differential cover and reading the numbers stamped in the ring gear or by counting revolutions of wheel versus driveshaft.
