Hello all, am new here and hope my questions aren't to dumb. I was needing some info concerning changing my current gear (3.55) to the 3.92 gears. My truck is a RWD and has the 8.25 axle. I use my truck mostly fo daily driving back and forth to work which is 80 miles each way at around 70-80 MPH which is about 2250 - 2400 rpm. I guess am trying to find out what all this swap in tails. I've been reading forums and watching videos but still not sure on all that needs to be done or what I need to do to prepare to the swap. Any useful help would be greatly appreciated.

Thanks in advance.

 

Any help??
