I have a 2003 2.4L, 5 spd, it has 4.11 gear ratio. and in the near future i plan of getting 33's for it. i am thinking ( correct me if im wrong) 4.88 would bring it back to factory settings. But i was wondering if anyone has changed them out by themselves. .or is it just smarter to have a shop do it. I live on a farm so im pretty handy with the tools i have. but is there any special tools needed also. . any advice would be great.
Thanks!:thumb:

You have a 5 speed manual? If so, yes I think you'd be happy with 4.88s. I'd recommend you have a professional regear it. We did the math for my buddy's regear and it is only going to cost him $200 more to have the pros do it vs him buying the parts and us doing the labor. It was a no-brainer for him.

I have duratrecs 31" i can use 5th gear untill im in a head wind, or going up a long incline. i can still drive on the highway doing 65 with the shift from 5th to 4th every so often, but from what i hear from others that have changed, they say they have trouble getting to 60.

I run 33's on 4.10 gearing, with a 5 spd and 4.0L
While theres a deffinent loss of power, its not that much to justify a regear for me.
I dont bother trying to use 5th gear unless its completely flat ground...but i dont do alot of highway driving, so it works for me.

If your on the highway alot, itd probably be a bigger issue

The PO got it geared to 4.10 cause it used to have the auto trans. Then he did a swap to a manual, but didnt regear

yeah i will probably go to a 32 with out changing my gears when i get my new lift. my work makes me drive to different office stores in a 40 mile area so i do a lot of highway driving. so i just thought the upgrade in gears would help out.

Going from 4.11 to 4.88 would definitely help out. You could even run a 33 provided you could clear it. Its a little different, but going from 3.73 to 4.56 with my 4.0L 5 speed and 33" tires made a world of difference. I also now have a discusting crawl ratio for a non Rubicon now too, its awesome :thumb:

What lift do you have, i saw that it says the 2.25 with 1" bl. thats what i want to run. and i have the 31" duratrecs right now.



EDIT!! ( i see that it says RC, how do u like that lift. i thought about going to the 2.5 with the .75" spaces for the 3.25, or should i just get the 3.75" lift with the 2.5 coils and the 1.25 bl

Yeah I have the 3.75" kit. I really like the look, it fits 33s nicely, and it's cheap. However the shocks are terrible. After 8 months I have OME shocks in the mail to replace them. Also I had some issues with the tcase shifter linkage after the body lift. Finally, its not a complete kit. You still have to buy a track bar relocation bracket and extended bumpstops. Other than that, its been a good little kit with pretty good flex. If I had to do it over again I would have saved a little more and pieced my own kit together using OME shocks and 2.5" springs, and a jks body lift for the same effect.

I am thinking about the 3.25 inch lift. I have 1.75" coil spacers. And it comes with .75" so I can lvl it if needed. And it has the relocation bracket. And looks like control arms too.( but is all that extra stuff needed besides the bracket).
So then I could get the 1-1.25" bl and a 1" mml... instead of the transfer case drop( people don't like the transfer case drop) and the front adjustable control arm. What do u guys think
