Question about gearing.

I have d44 front and rear axles. And this weekend I went to check the gearing. So after cleaning the mud off the little tag, it said the front axle had 3.7 or maybe it was a 3.9. The little tag was pretty banged up. But all the threads i have read about people having a d44 say that their gearing is something. Are my gears okay? Whats the pro's and cons of these gears? Thanks!

X2, all non-Rubicon TJs with Dana 44 rear axles come with 3.73 gearing from the factory.

D44 and gears

I am new to this gearing thing as well and had some similar questions. I found a lot out from reading up other threads, and the charts showing RPM's at 65mph w/ different gear ratios. There are a lot of variables not just on what the Jeep has but on what you want to do w/ it.
For example, I have a 2000 TJ w/ 4.0L and 3speed Auto, I have 3.07's (not good). I run 31's. At 65mph I am about 2300 RPM. I want to do some moderate trails like 2.5 to 3.5 but want to be hwy capable. I only plan on going to 32's so when I re-gear I may only go up to 3.73's or 4.10's. That way I have a bit more power off the line, better crawling on trails, yet am not screaming down the hwy at 3000 rpm's. At 3.73's I'd be about 2600 rpms. 4.10's puts me at 2900 rpm or so.
You are lucky to have a D44 and 3.73's, I wish I did, I would likely not even regear then for 32's, just lock em. I'd say think about what you want to do w/ the Jeep, tell us what engine and tires and tranny, and talk to some folks.

Okay, I have a 4.0L, manual transmission, and the 32" tires. Should i think about re-gearing or is this good for the ocasional wheeling?

Should be fine for a while. I ran 3.73's and 33s. Down shifted once in a while. Save the money and do other stuff.
