Since I am going up to 44s and I have to regear the fornt Dana 60 I am getting.... I am considering regearing the 14 bolt rear also. I currently have 4.88s and I really liked the performace they had with the 39.5s. So, what are my choices now... I know 5.13s are available in both. What about 5.38s? I think Dana 60s but what about 14 bolts? 5.87s also? ButI think pinion may be getting a little weak by then. I think 5.38s would put me at about the same gearing as I had with the 39.5s. Ken H.
