i got a 92 jeep with the 4.0 and a hp44 and 60 with 4.11s and just got a set of 38s what gears have people run in there diffs and still be able to move on the freeway like 65 70

i have the same set up only 37's going to run 5.13s soon a little under what is needed but if you go to 5.38s then i dont think youll be able to go 65-70

how fast do you go now anything done to the motor??

I run 4.56's with 38's. It is just a hair under geared.

IMO...4.88's with the 5speed should be good
