Gearing

So can somebody school me on gear ratios. My XJ has an AW4, Dana 35c open diff with 3.55's and 31" tires (29.5) my MJ has a BA10, Dana 44 LSD with 3.07's and the same BFG A/T's.

Besides the BA10 what's the best combo.

For highwayand/or towing?
For general driving? For wheeling, crawling?
 
This would be better suited in the Modified forum.

You might want to peruse this sticky over in the Modified forum as well: http://www.naxja.org/forum/showthread.php?t=80707

Thanks for the link but it really has nothing to do with modified. It's what I have, what came with both Jeeps, I didn't modify anything. All I need is some clarification, in English, not algebra. As in, which combination works better for which application.

I don't really plan on fabbing or anything other than swapping in an AW4 or AX15...and possibly regearing if necessary. I didn't think that really belonged in Modified. I see much more complicated issues in this forum but I need some info past putting on new wiper blades.
 
whats better is the setup with the auto trans becuase it has 3.55 gearing and a torque convertor.

i have 31's with the ba-10 trans in my 89 and when i had stock gearing i thought it sucked. when i regeared to 4.10 it made it perfect.

only thing i would do with the auto setup you have is to add a trans cooler.

schooling you on gear ratios? did you pay attention in science class when going over mechanical advantage and simple machines?

My Dad always told his friends that I was going to end up working for NASA--he said he knew it was so because the only thing I took up in school was space. :dunce:

Well,

a. That was 35 years ago, a few brain cells have chafed off since then.

b. I was more of a language and biology man.
(as in "prolly" is not a real word and I know the latin name of every tree and plant, and most of the bugs on my acre of land) but I ended up being a chef.

c. 35 years ago I also thought programming computers was a waste of time...who knew?

Anyway, thanks for the calculators and info. I really am a quick study once I grasp the principles.
