Running 33's on a D44 rear end and 3:73

The title says it all. I have the opportunity to upgrade from my 31's currently installed to 33's. Is it worth it to run the 33's without changing anything in the rear? My tranny is also automatic.

I know the D44 will handle the tires no problem, but after searching the forums here, it seems like the sluggishness / drag on the drivetrain might make it not worth it.

What are your thoughts? Is anyone running 33's on this setup and what is your experience with it?

with your 2002 3-speed auto, 4.11s/4.10s is recommended.

im running 33s with 3.73 gears. not bad really. i know that the right gearing (4.56) would be ideal, but i have no problems getting up to speed and using 5th gear (i have a manual). i heard that the autos are even better. might be a good idea to borrow a friends 33s and try it out. although im sure you will be fine.

The 3:73 is barely acceptable in the mountains with 31's. It will be OK if not in the mountains or not driving grades. You will be switching out of O/D often.

I have a Manual, but I have 33" tires and have no problem getting up to highway speed. Yes, in a perfect world I would have maybe 4.11 gears, but the 3.73 are perfect for now. You could get bigger gears, but it won't be bad for the jeep or make it too much slower. Maybe just hurt your gas milage a little

I appreciate the feedback. I can get the 33's for $140 for 5 of them; 1 is brand new the other 4 have 3,000 miles on them. It is such a good deal I am not sure if I can pass it up. The crappy mileage and drag might annoy me enough to not want to do it though.....

His transmission doesn't have O/D

It won't be that bad but you'll want to rehear eventually. I have been running 3.07s for a while and cant complain. Will have 4.10s soon though.

For $140, I'd buy em, try em. Like em, keep em. Don't like em, sell em for a profit.

I'm considering the same thing and was told that with the 3 speed auto, we'd be fine.

having swapped from 3.07s to 3.73s, i couldnt believe how sluggish my jeep was. 3.73s are great (in comparison).
thats a killer deal on tires!!

I have that exact set up with 3.73s. I would say that it works okay but in certain situations the engine bogs a bit and the trans has a hard time finding the right gear. I am wanting to upgrade to a 4.26 ratio to improve performance a little bit. Now I just need to find the funds to do it!

4.26? i have never heard of that ratio for a tj. and nobody would pick that over 4.56 with 33s anyways..

I'm running I6, 3 speed auto, 3.73, rear D44 and 33s. It's acceptable. However, I do miss the torque onroad, especially when using the A/C.

4-low offroad has so much torque it doesn't matter.

For $140 you can't go wrong, I'm running 36s with 3.73s. Granted I don't ever use 5th gear with my manual. I got 17.5mpg the other day on a hilly 143 mile trip the other day. It definitely doesn't have the on road torque and low end as it would regeared or with smaller tires, but it's not a complete dog either.

I apologize, the actual gear is a 4.27. My setup with 33 inch tires and a 3 speed automatic 4.56s are way too low. The 4.27 is just a bit lower than the 4.10 and hopefully will give me a bit more get up and go without too much RPM.

Here is information from the Currie web site:
Part #: 44-427S
Our Price:
$209.95

Description: Dana 44 4.27 ratio standard rotation ring and pinion set.
Unit of Measure: Sold each.

That's what I was thinking about! I saw some 4.27s made by Yukon (for example), but wasn't able to find a matching set for my Dana30 front. Have you?

Thanks! I guess what I wasn't finding was 4.27 for a high pinion D30.

won't work on a TJ. those are standard "long pinion" D30's, like CJ's...TJ's are short pinion.

here's what is needed for a TJ D30: Shop By Axle Type - Dana Spicer - Dana 30 - Dana 30 Ring & Pinion Sets (TJ Short)
