Bout 2 years ago i was at work with my 2002 3/4 silverado. My co-worker pull next to me in his 2003 single axle 1 ton silverardo. Working in a machine shop we were out in the parking lot doing a full inspection on the rigs and the only difference we could find between the 1 ton and 3/4 ton was the leaf springs in the rear. So what i want to know is with our older rig when guys say they have converted to a 1 ton, is it any different than my converted 3/4? Aren't they still using the same 14ff as my 3/4 ton?
