Alright I need to regear.... I have a 98 cherokee rolling 35inch tires, auto tranny and an 8.25 rearend.. I would like to hear from people rolling the same equipment with aftermarket gears... I cant decide what to go with , 4.56 or 4.88.... Im looking for the best power curve and best fuel milage, I do a lot of highway running, and I would like to beable to pull my trailer with my fourwheeler and dirtbike with out constant downshifting.... So please give me input, this is also my daily driver, so I emphesize best fuel milage..

With your 8.25 rear axle, the tallest gearing you can get is 4.56. Looks like your decision is made for you unless you want to replace the rear axle...

Let me get back with you on that I will have to find it again, my friend showed it to me on the internet, (and yes I took another look to make sure that its for the 8.25) I will ask him what the address was again....

If you can get the 4.88s by al means get them 4.56s are ok but i wasn't happy with them.

I haven't seen 4.88 for the 8.25, but that would be the way to go with 35s.

theres no way, have you ever seen the top of a 456 ring gear? Goodluck with 488s! :rolleyes:

If I were running 35's, I would be turning 5.13 gears....minimum.

My vote is that the 4.88's don't exist for the 8.25 Chysler, they do exit for the GM 8.25 IFS. :eyes:

not possible. nobody makes em or else everyone would have em.

GM 8.25 is a reverse rotation front axle in Yukons... pain in the butt to setup...

Can you get 4.88's for a ford 8.8? I was wondering the same thing about gearing for 35's. I have a 8.25 also but I'm looking at an 8.8 for the disks. If I could get 4.88's for it that would be another plus.

Alright I found the website again and called because it said 8.25.. After talking to the sales rep he corrected himself and told me that it was for the GM 8.25 and that there is a glitch in the system that classified it under the Jeep axels... So it looks like I will be getting the 4.56s... Also for those of you that have these gears what kind of fuel milage do you get? and is it good power?
