Hi, I have a 1999 4X4 Suburban 2500. I have a Cummins and a 4L80E. The axle ratios are 4:10. I want to go to a 3:42, keep the larger front ring gear size, and a 14 bolt full floater with disc brakes would be fantastic. I can find 3:73 very common and 4:10. I have been looking for a 2500HD, with a Duramax or the big gas motor. Any idea of what years and models would have the combination I'm wanting?
