Gear Ratio for 33's/AW4

To plan for an upcoming build what would be a suitable ratio for my Cherokee XJ with the 4.0/AW4 running 33x12.5x15's?

The XJ will be my daily driver going at least 50 miles a day for school/work. Id like something thats going to be easy to drive on road daily but still perform well when i wheel on the weekends.

im leaning more towards 4.10's or 4.56's whats your opinions?
(D30 Front / Ford 8.8 Rear)

Also: Anyone run Aussie Lockers front and rear on a daily driver? Is it rough driving on the street and does it add any wear to the tires?

I'd go 4.10. I'm running 3.73 with a 5 speed, and find thats perfect for the street IMO and just right for the trail. I have low when i want to go lower

I was also considering the 4.56's, But my dad runs 4.56's in D44's with 33's in his YJ with a 5 speed and by 5th gear hes running at about 60MPH at 2.5k Revs. Just seems a little low for me maybe if i was running 35's it would seem better.

Ill still look into it thought and i appreciate your reply (:

Im a big fan of your XJ btw shes a brute.

Thanks.

For the gears you should compare apples to apples. I have had that setup: 4.0L/AW4/4.56 and 33's and it was close to feeling like stock again. In reality I wouldn't have minded even a little lower (4.88).

Don't be afraid to go with lower gears. If you don't and opt for the 4.10s you will likely regret it later. You will be hard pressed to find anyone that went with 4.56 and regretted it because it was too low.

Ill take it from your experience with that setup and ill opt for the 4.56s. I think i would be happy with the 4.10s but just to be safe and future proof me ill run the 4.56's in case i ever do decide to run 35's or larger.

Thank you again (:

With the 5 speed you want to go one ratio lower than with the auto. I would go with the 4:56's in your case for sure. I run 4:88's with the 5 speed and 32's on the TJ but it has the 4 cyl. and needs all the torque available. Like Eric said I have never seen anyone unhappy with the 4:56 gears and the AW4.

4.56-4.88, if you wheel/carry camping/wheeling gear Id go 4.88. I have 4.56 with my 4.0, ax-15, and 34s and I definetly like the 4.56 but it would of been nice to go 4.88 for extra gearing while wheeling.

Me, too. Granted, my XJ is heavy and the engine a little tired at 200K. With stock weight and a fresh mill I'm sure the 4.56 would be fine.

Really, the only problem I have is the need to downshift to 3rd on the hiway more than I would like (I generally drive 55-60 and never more than 65). FWIW, my RPMs are exactly 2250 at 65 mph via the GPS.

PS: There is no way I would go any higher (numerically lower) than 4.56. I had a full set of 4.11s ready to go, then reconsidered and went 4.56.

Do you have the 8.8 yet? You never mentioned if you already have one or not.....
If not, why not get one with the 4.10's in it and try it first?
If the 4.10's are good enough for right now, then either grab a 4.10 dana 30, or leave the front driveshaft out for a while until you regear etc.

Gearing is an expensive hobby, so if you can see how you like the 4.10's before spending a penny, that sounds like a good idea to me.
Just a thought....But surprised no one else asked if you already had the 8.8 or not, unless I slept through something.

Definitely go with at least 4.56's. I'm running 32's with 4.56's and am turning a measly 2200 RPM's or so at 60 MPH. You'll be turning less than that with one inch taller tires.
