trucks. Even with the taller gears you are not going to be able to
safely pull 10K lbs with a burb. I would check the codes and see if
that rear end is factory or if somebody changed it before you. I would
change to a more factory set, something like 3.73 I think, even less
probably. Not sure offhand what most of them came with. I would check
out gm-diesel.net for more info.
Cars/trucks with overdrive require gear ratios in the 4.10 range.
Gives the pulling power required and economy when cruising at higher
speeds.
