Gearing Question!

WELLLL I have a 89 yj and my rear dana 35 ring and pinion broke while being a showoff... Lol But I've managed to find new ring and pinions for a steal but they dont match my original 3.07's its 4.11 gears. My question is, that if I put these new 4.11 gears in my rear and I still have a 3.07 front what will happen to my ride when I put it in 4x4?

All KINDS of wicked shit........ if you are on dry ground....wind up....hop.... possible.

If you are in a slip ability(snow, mud, etc)... not as much, but still very unrelaible.

So if I keep it out of 4x4 until I get different gears in the front itll be fine though right?

You'll be fine as long as you don't put in 4 wheel drive.

the same as the rear... basically.

Usually they are a matched set, like 3.07 rear, 3.06 front, or 4.11 rear and 4.10 front.

A slight difference is typical, but a wide difference like your suggesting will be bad. You can break things if you ever put it into 4x drive with a 3.07/4.11 combo.

Yes, you can run it if you NEVER put it into 4x; but the first time you do you will immediately realize there is a dramatic problem.

What size tires are you planning to run?
What motor do you have?
What transmission?
What do you use the Jeep for?

answer all of these to determine what gear set you will want. 4.11 is decently low, and very low if you are running stock sized tires. But may be just right if you are running 32" or 33" tires.

Drop the Dana 35 like a bad habit. Go with a Ford 8.8 ,Dana 44 ,Isuzo
Dana 44. Don't put a dime into a piece of junk like the Dana 35!
