the od ratio is .69.

I had 4.56's with 32's in my XJ, it's overdrive was .7:1, so pretty close. I spun about 2450 rpm going 70, which is barely higher than it did with stock tires/gears. I was able to pull down about 18/19 mpg on the highway with my stroker.

4.56 isn't a bad choice but if you aren't driving on the freeway imo you can never go too low

Wow, this thread kinda rose from the dead. I did buy 4:56's and think I will be extremely happy with them. BigBChevy is a busy man. I will report back when the gears are in.

So the 4:56's have been in for just about a month now. The drivability of my LJ is way better now. At 70 MPH it cruises at about 2350 RPM's. As far as mileage goes, it's actually the same as I was getting with the 3:73's. The jeep was bought in Florida and driven home to Michigan and it averaged 15.5 MPG. After the 4:56's were installed I drove it up to the Keweenaw Peninsula in the U.P. and back and it averaged 15.5 MPG. Around town milage was and still is 13 - 14 MPG. All and all I think the gear swap was a win. I got way better drivability and didn't loose any gas mileage.

Another update:
I took the LJ to Silver Lake sand dunes this weekend. The 4:56's seem to be a perfect choice for my wants/needs. I aired down to 10 psi and did almost everything I wanted to do. The only thing I couldn't climb was the far right (west?) side of test hill where it was very steep and I blame that more on the automatic than the gear ratio. I checked milage on the 160 mile trip home and got 17.1 mpg. I was running around 68 - 70 mph on the highway for about 125 miles and 55 mph on the backroads for the remaining 35 miles. All in all I am extremely happy with the drive ability and offroad ability of the 4:56 ratio and the 4 speed auto.

It was a demo locker so I let them know that it didn't work. LoL. They are going to do more R&D to fix the problem. They sent me all new bearings and I'm just running an open front end for now.

How far off is your speedometer or did you change the gear in the t-case? if so how did you know what gear to buy?

I changed the gear. If memory serves me correctly I had to put a 39 tooth in it. I told Jared at Americas Most Wanted what tires and gear ratio I am running and he told me what tooth count I needed. I'm sure there are calculators online. I think Quadratec has a chart in their catalog also.
