I had a 1990 Cherokee and just bought a 1993 2 door with an AX-15 and a 4.0 HO i was told it would be 3.07 gears,my 1990 had 3.55 gears should i change them and put them on the 93. i took the 4.5" lift out and am putting it in the 93, will be running 31x10.5 TSL Super Swampers. Thanks in advance for any help I'm kinda new to this...lol

 

the're not that different, i dont think it's worth the trouble. if you go 4:10s then i'd say yes.

 

I would say go for it, 3.55's is like running 4.10's on the Manual tranny. (the way the gearing is set up in the tranny) you have some power lose and some different gearing in the auto and it requires the 3.55's to be equal to the 3.07's on the manual. so if the axles are the same i would say go for it! but if your 93 has the 8.25 and your 90 D35c then i would run the D35c and then rebuild your 8.25 with 4.10's or 4.56's if you plan on running much bigger. i run 3.07's and 33's with my AX-15 just fine(faster than stock still). but deeper gearing would be nice on those up hill highway grades

 

so the 93 might have a 8.25? how would i be able to tell i know the 90 had a Dana 30 front and Dana 35 back...so i should change it then? like i said I'm kinda new to this sorry if you guys have heard this a million times...i don't want to **** anyone off by asking the same questions over and over

 

i do not have the link off hand but look up the axle identification. i know there is a post on here somewhere about it search here or google i will find the link when i get the chance

 

Do you have ABS?

 

http://accuautoparts.com/technicalhelp.jsp# go here click on gear ratio calculator you can put in oem ratio, tire size, new tire size itll tell you approx. the new ratio needed to match oem

 

 

here is the dana 30

 

I would say do it. It's a good mod for no money spent.

Even if it has the D35, you're only running 31's. Should be no problem w/31's.

 

I had a 93 5 speed with 410's and it was a bit overkill, 1st gear was worthless and on the freeway it was revin high. I would stick to the 3.55s. It will still run good on the streets

 

thanks for the info guys...3.55s it is

 

Nice.

And lol at the auto w/3:07's.

Does the '90 still run? If it does, you have to drive it w/the new gear swap and tell us about it.

 

lol no i took the axles and lift out and scraped the rest...got 215 dollars for it
