Have 91 Kick with the auto gears the 4:62's

Rear end is blown, am going to pick up a rear end axle to axle from the yard but with the 5:13's from the 5spd.

Is it safe to drive highway and will I still get the benefit of the gears with just the rear end the 5:13 and the front still the original auto 4:62.

I do recall a Jeep guy who had different ratio's ..410 up front and 488's in the rear but I also think he didnt run it for long

will be find in 2wd, probably work ok in 4x4 in snow and really slippery mud but it will blow the tcase apart in anything high traction

get the front diff as well change that out. run a set of 31's and your back to the factory spedo settings as the stock auto was with 4.62's and 205's that they come with factory.
