4.88's worth the money?

I got a 97 tj with 33's. its a 4 banger 5 speed with factory 4.10's. ive been driving it for a while like this and i kinda got used to it being slow as hell but ive been thinking of getting some 4.88's put in it. Im thinking it'll cost about $1000.. is it really worth it?

Absolutely, it'll restore much of the performance lost by the larger tires and it'll feel like a new Jeep afterwards. Your fuel economy will probably go up a small amount too since the engine will be operating more efficiently with less lugging. 4.88 is the right choice for 33" tires providing your transmission is the 5-speed and not the 3-speed automatic.

yea thats what i was hoping for. I dont know much about gearing, so with 4.88's will it be able to do more than 70 mph on the interstate? right now when im going up hill it slacks off to about 55..

You'll notice a dramatic power increase and 5th gear will be a lot more useful. Speed will be bumped as well, as will it making 1st gear feel like 1st gear again and not like you're starting off in 2nd gear as it does now.

it'll feel like a whole new vehicle power wise. its expensive, but it's because its worth it.

absolutely!!! i didnt realize how bad my gears were before i swapped them out, i have the 4.2L though. i was on 33's with 3.07 gears (i know right!) didnt know it because thats how i bought the jeep and the PO couldnt tell me what they were... needless to say i went to 4.88 and 36" tires and can actually use 5th gear now, its awesome!

with the 2.5L regearing is the best option over any power upgrade (besides maybe a turbo) you will definately feel the difference.

My 97 has the 4.0 now a 5 speed and 33s it even felt like I was taking off in second gear but after the re gearing(i went with 4.56) it did feel like a new Jeep and the power increase was amazing.You will not be sorry guaranteed!!!!!!!!!!

I was planning on 4.88's for my 35"'s. I have the 4.0L. If 4.88's brings back the 2.5L to stock with 33"'s. I should go a little deeper then. Maybe 5 somethings but that will be a good thing, after the tube fender install and some new axles I want to try rolling on some 37"'s or 39"'s.

4.88 is ideal for the 4.0L and 35" tires if you have a manual tranny. That's the combo I ran when I still had my 5-speed and I never wished for any different axle ratio. At 70 mph, it spins the engine at about 2700 rpms with 35" tires, 5-speed, and 4.88 gearing.

I would do 4.88's if I had to if you have a 44 front and rear go 5.13's! I have them in my 4 banger 97 tj and it moves nice and good for a 4 banger!

If you haven't gotten more out of the insurance company than you deserve, then you haven't screwed them nearly as much as they have been screwing you for the past xx years.
