Yea I don't have max tow so it came with 3.73 if only I knew before I got it I would have gone with 4.10s but it's fine though with 3.73 an 37s.

I thought all Rubi's came with 4.10s?

rb1boxer_3

Yea I thought so too I've read that they just made it an option like 2-3 yrs ago

You have a loss in power as you are running heavier and 15% larger tires, so your power is definitely diluted. This may well be something you find adequate, but you are definitely exhibiting less power where the rubber hits the road.

I am fixin to re-gear. I have 285/70/17 Goodyear MRT with Kevlar on 9.5" ProComp wheels. I have 3.21 and looking for somthing in between range. I use my jeep for daily driving, but I want to beef it up to do some rock climbing and trail riding with the kids. Not looking to go crazy, but do want to have fuel millage, highway speed's but torque to play around where ever we end up. I am looking at 4.10's, but from what I am reading, 4.56 or 4.88's? What should I do?

You want 4.10's for sure, especially if you have a manual. If you had 35's, then 4.56's would be in order. If you plan on going with 35's, then maybe consider 4.56's.

Oh ic. Well it doesn't feel all that bad like how some people say so its good I can deal with it. I just have one question if you can help me with. After I put the tires on my procal wasn't working to fix the speedo and rpms so at 70 it was around 2500 or so now my procal finally worked and at 70 it's around 2100 is that right.

Ok. What about info on some good axel's for an upgrade. I will be driving it more than likely to Hot Spring's Ark. to the trail rides there and wanna make sure I can drive it back with my axel's intact! I know stock axels won't last, so I better upgrade.

Sounds about right, 37s measuring 35", 3.73 gears, possibly 4.10s. Check your speedometer and verify the results with a gps and that should resolve things for you.
