Awesome because that's what was installed today. LOL, however I'm curious, will my MPGs be worse with 4.88s over my 4.10s? Because I'm already at 10-11mogs

I don't know what will happen to your mpg, I'm sure you will find out for yourself once you run a tank of gas through it.

I can say you'll love the 4.88's over the 4.10's. I just finished the 500 mile break-in period on the 4.88's I put in my 2.5 w/ 33's and it's so much better. I can actually use 5th gear again.

Especially since the OP has a Dana 35 in the rear which isn't strong enough for 35's. I agree with the others, go 4.88 for those 33" tires... that's the optimal combination for the 2.5L engine.

I also run 4.88's with 35's...i'd run 5.13's if i could.

As for your mileage, i think you'll stay the same or could even do better because the motor wont be working as hard to turn those 33's.

In the winter i get around 15 but summer/spring i get around 18-19...i also dont have a lot of weight on my tj and live above 5k feet which helps my mileage.

Owen are you running the 2.5L engine and Dana 35 rear axle like the OP is?

I'm putting 4.88 in my dana 44 front and 35 rear for 37" tires with a 4.0. Bad idea or good? Opinions?

Something's not right, you have a Dana 35 in the rear and a Dana 44 in the front?

Perhaps you're confusing the front axle... the TJ's normal front axle is a Dana 30 which looks a lot like a Dana 44. Only the Rubicon came with a front Dana 44 and that you say you have a Dana 35 in the rear means you don't have a Rubicon which only comes with a Dana 44 in the rear.

If you do truly have a Dana 35 in the rear, it's not even close to being strong enough to run 37" tire. In fact, a Dana 35 is not even strong enough for 35" tires. They like to break an axle shaft when running too big of a tire which will ruin your whole day.

And while a front Dana 30 can hold up to 35" tires, it's definitely not up to 37" either.

Lol I never said it was in stock form. I bought a g2 dana 44 for my front with an arb locker but do not yet have the money to do the rear, so the 35 is just to get to and fro until then. I wont be taking my 35 off roading until it gets upgraded, rather from storage to storage while I make my girl a beauty. I just want to know if 4.88 is a good gear ratio for 37" as I heard it was. I will get a dana 60 rear once I have the money, until that its a 35 with 4.88

Oh ok, now that combination makes sense. I'd go 5.38 for those 37's assuming you have a 5-speed manual. While 4.88 is ideal for the 4.0L engine with 5-speed transmission and 35" tires, it's not quite enough for 37's.

I already have 4.88 in the g2, so I want to wait to change them. What would be the result of driving 4.88 with 37s? Would it just drive slower?

Less power, you'd be downshifting more than you'd like. Not an impossible combination, it would just be a little frustrating at times.

Haha appreciate the feedback guys. Just got her home, towed her home (it was a 126 mile trip from where she was) I drove her around the parking lot. I can tell a throttle response difference, she actually moves without having to push her hard!!' I love the 4.88s

4.88 its a good number.
A friend of mine has 5.13 if i remember correctly running 33's
And its much better with the little squirrels hahahaha plus is a vehicle only for offroad use mainly so rpms on highway are pretty high but he likes the extra power and also for him mpg is not a problem.
