What Gears w/ 35s and 6 Cyl. /4-Speed Auto

Guys, I am about to make a big investment and would like some real world opinion on gear selection. I have already run all the gear ratio calculators and feel comfortable with their results but I am not ready to sink a couple of grand on sheer theoretics. Hince, I want your feedback. Here's the application:

- 2004 Sahara w/ 6 Cyl. and 4 Speed Auto
- D44 Rear w/ Trash-Loc / D30 Front
- Plan on 35" BFG MTs (Currently Running 32" BFG ATs)
- Mostly street with mud for offroad. No Rocks.

Should I be looking at 4.56s or 4.88s? My biggest concern on the driveline is the crappy OD and shift characteristics of the 42RLE, 4-Speed Auto.

you'll probably want to go with the 4.56's since you have the automatic. If you went 4.88's, your highway driving might be a little unbearable. Hope this is correct info.

I am planning on 4.56 with 33's and the 4 sp auto. I may go to 35's someday so I'm kinda interested in this too. With 33's and the stock 3.73's it's probably comparable to your situation. Liveable but leaves much to be desired.

I'd recommend 4.88s.

I run 35s/4.56/3 spd auto and I wish I would have went with 4.88. And I don't even have an OD.
