|Rabit||I have a 99 with the 3 speed auto, its on a 3.5" lift and 33s. Someday looking to put it on 35s. What ratio would I want? It is my DD and i do take it offroad, but definitely more highway driving than anything.|

I can't really say how my fuel consumption changed between all my various axle ratio and transmission combinations because it's so bad I try not to think about it.
But regearing to a lower ratio to increase engine RPMs can actually improve (reduce) fuel consumption if it brings the engine RPMs back into where they become more efficient again.

I wanted to go to 4.88 and 35" in future, but now enjoy the 32" and got scared of pushing 35" mass. So I will try to sell the gears and buy 4.56 or 4.10.

I also have a shot at a 8.8 from a mustang with posi rear end and disk brakes for 350...
whats my best choice..I found a good shop who said they will do what it takes to get it on my jeep for a max price of 300 or less. Thanks

not all 44s are the same

Have an Hp 3:73 dana 30 lined up for 100 tomorrow and a dana 44 with 3:73 for 300 I found local. Cant wait to get em it.

|timritchieblue||well, i get good mpg in town, but running 70mph, my mpg suxs... so i would recomend 3:73's for casual commute|

I was just reading through all this, and I have a question too. 3 speed auto, 4.0 97 on 33's would 3.73 be better for highway/city driving with minimal offroad time...or is 4.10 just better all around.
Reason I ask is I can get my hands on a HP dana 30 with 3.73 and then just regear my D35 to what is needed. My TJ is for college commute so I need best MPGs possible and the snow gets bad so I want to run the 33's...again, mainly on the street. so its 4.10 or 3.73 for me?

|n8smitty||I just put 33's on my 2004 with Auto Trans. Would 4.10 be a good gear to go to for mine as well? I did a little online research and that is what I'm coming up with so far. I have 3.73 gears now and it seems fine, but I do want to upgrade it.|

|BillR||I run 35s with 4.10s and the 32RH auto tranny, and I think it's absolutely perfect for a DD/wheeler. I couldn't imagine putting up with 4.56s and 33s using a 3-speed auto.|

Dittoe on the 4.10s
With your 3-speed auto, and 33's, 4.10s would be the best.

As many of you know, I converted my 5-speed manual transmission to the 3-speed automatic last year. I am running 35" tires and had regeared to 4.88 previously when I still had the 5-speed manual transmission.... a great combination.
So when I converted to the 3-speed automatic tranny, it was with the same 4.88 gearing and 35" tires... my engine rpms are now excessive at 65-70 mph so I tend to cruise at 60 mph now. My 35" tires and 4.88 gearing produces about the same engine rpms as 4.56 and 33" tires would produce with the same 3-speed automatic. They are excessive. That's why I'm recommending 4.10 with 33" tires, the rpms it produces with that particular 3-speed automatic transmission (it has no overdrive) are ideal.

|Giancarlo||i have 97 3 speed auto with 4 inch lift and 33.. still 4.56 or 4.10?|
|02-24-2009 08:04 PM|
|Jerry Bransford||Your 2000 TJ's automatic transmission is a 3-speed. So while 4.56 is the usual correct recommendation for 33" tires, that is only true with a manual transmission or the newer 4-speed automatic transmission that is in 2003 and newer TJs. For your particular rig with your 3-speed automatic, 4.10 is the appropriate ratio for 33" tires. 4.56 would be too low of a ratio and your engine would be doing 3000 rpms at 65 mph.|

|03rubi||Ditto on the 4:56 gears and a 1" body lift. Should work out fine and the 1" lift will save you $$ compared to going to a higher sus. lift.|
|02-24-2009 06:56 PM|
|Giancarlo||will 4.56 bring it back to stock because i have the same setup.. i just want the origina restore performance and hopefully restore some miles per gallon?|
|02-24-2009 06:45 PM|
|4point||Do a 1" BL, 33" tires and 4.56 gears.|

4:10 gears ok for 33" 12.5
New to this forum, and need some advice. Im upgrading gears and i wanna run 33" 12.5 but i dont know if i should go 4:10 or 4:56. it is my daily driver and its still my priority, but i go off road a lot. Mostly beach for fishing but would like to get into bigger trails. I have 3" lift kit with 31 11.5 mickeys. what should i do?
