Sorry Guy, But I read your post 3 times and have to ask... Cloud you please rewrite your ask?
Resurrecting incredibly old Post. I can't believe this hasn't been touched in over 15 years. But I am trying to re gear my 2001 Jeep Cherokee I'm four and a half inch lift and 33 inch tires with a 3.55 gear ratio. I wanted to be 100% sure but I was thinking about upgrading the rear end gear ratio 4.56. after the front bumper rear bumper skid plates spare tire frame stiffeners I'm running really high RPMs and only getting about a hundred eighty miles to the tank.
With 33s and 3.55 it would cause you to be running a low RPM. Re-gearing to a 4.56 with 33s will raise the engine RPM higher than you currently run.

All right meeting of the minds gentleman I have a 2001 Jeep Cherokee automatic 4 1/2 inch lift with 33x10.5 all terrains with aftermarket front bumper rear bumper spare tire skid plates and frame stiffeners. My Jeep is my daily driver I really don't go very far other than 30 miles from town.but occasionally I take long trips up to Maine on the highway. To the best of my knowledge I have 3.55 gearing ratio in the rear end my vehicle is getting pretty damn heavy and I'm starting to get really high RPMs going anywhere over 55 clocking around 3000 I got a little bit of research and I figured out I'm pretty sure I need a 4.56 gear ratio. Let me know your thoughts I'm open to anything

If you do mostly highway driving then I would suggest 4.10's for 33's, unless you live in a higher altitude climate. If it's the daily driver/weekend warrior then I would go 4.56 for the offroad side. It really depends on what you want to do exactly. 4.56 gears would probably be your best option overall though.
Also on a side note, I'm assuming your jeep is 4x4? Because if you change the rear gears you have to change the front also. Otherwise bad things will happen.

Enter some JK takeoffs and watch the 4.0 struggle to keep the MPH with cruise control set to 70 MPH up any semblance of a hill. I have children living in Tennessee and those hills do not hesitate to let me know that the 4.0 need help.

Since it appears you make this drive often, have you considered a second set of tires and rims, something better suited for long distance driving?
You might be happier on some smaller diameter, quiet street tires, instead of wearing out expensive off-road rubber on long drives. With a floor jack and impact wrench, tires can be changed in 20 minutes.
ok, you say 33's w/3.55 gearing w/AW4 (auto) = 3k rpm at 55mph?
Something wrong here... if the above is correct you need the transmission looked at... it's slip'n

I agree with this. I'm on 4.10 gears and 32's. I'm around 2000 rpm. A bit sluggish too. I was fine on 31's. I am thinking 4.30 gears, as I run highways a lot.

The only person I know of who suggest 4.30 gears which is what I have in mind. I know they are available for the early XJ D44 I have in the back but I do not know if they are available for the JK Rubicon D44 I am building for the front.
The 4.30 gears are on the top of my wish list.
