Anyone know of a good set of 4.10's or 4.11's for stock front XJ diff and 8.8 Rear?

I've been trying to find a good set of gears for my XJ to step down from the 4.56's I have it now but cant really decide on anything. Im looking to drop tire size from 35's to 33's and stepping down gears to hopefully pick up some MPG. Tired of getting 180-195 miles a tank with the set up now. I dont know if it matters or not but I have ARB's front and rear. Any help would be greatly appreciated!

Thanks!

I have a 8.8 Ring and Pinion 4.10 pm me if your interested

If you want used gears i would pm CSBYJ he is currently going from 4.10s to 4.88s on his D30/8.8". I'm sure he would make you a deal on his old gears.

If you didn't have the arb, I'd offer an axle trade. But no cash for anything like that.
Talk to some naxja vendors, good deals to be had.

Sweet thanks fellas! Ill hit those guys up and ill check out some of the vendors

I have run 33" on both 4.10 and 4.56 and did not see a decrease in mileage with the 4.56s.
33's, with 4.10 gears , are doggy. You will find your XJ downshifting any time the road heads uphill. Since you live in Colorado, you will not be pleased with this.
I suggest you save your time and money and stay with the 4.56 gears.
Built XJs, with lifts, large tires and lots of added weight will never get the mileage they did when stock. It's just wishful thinking.

Rawkhaussupply. Best prices by far.

Yea I've been thinking about that as well, my buddies taco on 35's and 4.10's gets roughly 3-4 mpg better than my XJ but it is a bit sluggish of the start and hitting the hills.
Thanks for the advice! Might just drop to 33's and see how it runs

I switched to 4.11s, in 2006, when upgrading to 31" (we were getting ready for a trip to the Rockies). I was advise by a few knowledgeable forum members (including Cal) to to go straight to 4.56s but dumb me didn't listen.
I added a second set of wheels a couple years ago, a set of 33X10.50-15s, and was disappointed with the drop in power when using the 33"s..
Last fall, I re-geared to 4.56s and added a locker to the front, already having a TruTrac in the rear. My mileage came up a little and the surprising thing was that when running the smaller diameter 31"s, the mileage doesn't noticeably change.
The increase in acceleration was nice too. The engine is happy running a couple hundred RPMs faster.
