So I have a M1165A1 with a 3.08 Diff. When I was buying it I thought I was going to be able to drive over 55 mph but I was wrong. Does anyone know if it would be possible to buy 2 sets of ring and pinions and have them installed? I think that would get me to 70 MPH. the truck is not going to carry armor anymore.

Go drive it. Verify it is shifting 1-2, 2-3, 3-4. If it’s not you are in limp mode which explains the 3000 rpm @55. Limp mode is second gear only. Limp mode happens when the transmission has issues.

It’s definitely shifting 1-2,2-3,3-4. What type of RPM should it be at with a 4.08 differential and 4l80e?
Member "ACTION" reports: I get 2000 rpm @ 50 mph, 2700 rpm @ 70 mph with 6.5 TD, 4l80e, 3.08 diffs, and 37” tires
