Thats a pretty broad question/answer--it depends on the jeeps use and whether it's a DD or not-

The GENERAL regear ratio, for DD/light off-road is 4.88/1 ratio and for non/Rubi/medium off-road, it's 5.13/1 ratio-
For the Rubis/w auto--5.38/1 ratio, because the Rubi is supplied/w Dana 44s (HD) and they will support the ring/pinion size, which is larger than the Dana 30 ring/pinion-
Mine is the auto (mod)/w 5.38s and it's super efficient-
Remember, you SHOULD haveit done by a reputable suspension/gear shop--not dealer and the cost will be from $1200 to $2000 bucks-
There are other additions to consider while regearing, but the above is a general cost JUST for the gearing-
