jeepin_jer1 I second that motion!

Jerry Bransford Your 5-speed is an NV3550, the AX-15 transmission used behind the 4.0L engine was last used in the '99 Wrangler. For your NV3550 transmission and 35" tires, you'll be much (!) happier with 4.88 gearing. I ran that combination (35" tires, 4.88, 5-speed transmission, 4.0L engine) for years and it was optimal for street and trail. No, 4.88 will not produce too high of an rpm on the highway, it is just right for that big and heavy of a tire.

Spread_cheeks_with_a_jeep It's a 5 speed standard. I don't know if its the ax-5 or ax-15.

Jerry Bransford Ok but what transmission and model year? 4.56 isn't often the best choice for 35" tires.

Well I just got my jeep about a month ago. It's a mostly stock jeep wrangler. The guy that originally owned it put a 4.5 in lift with 35's...with that being said, nothing in the driveline was done. It's the 4.0 Columbia edition and I think those come standard with the 3.07 gears which is not cutting it at all for those tires. Who knows though! I'm new

Looking at getting my D35's re geared to a 4.56 ratio. I just wanted to get y'all's input on brands I should go with before I buy some foreign crap.
