regear was done after the 37's. Difference was noticed in the off line acceleration and the ability to go up the steep paved grades without having to use the truck lane. Even with the gears we had to work the motor to get up the grades but at least didn't have to use the truck lane. We also noticed that obstacles were a tad easier. On the other end of the spectrum this will limit your top end. For instance we could run about 80 if we needed to with the 4.10's and 37's with no real issues or concerns. Now when we get above 75 indicated the gears start to hum pretty good. Have been told by others we are near 80 at our indicated 75, despite the reflash for the correct gear.
5.38's, altitude pulley and 37's appear to be good combination for the 3.8l for how we use our jeep and where we wheel.
