My friend has an 86 Chev truck with a D44 in the front and he says a D44 in the rear. This truck is heavily modified by someone else and thats what the guy told him what was in the rear. My friend is going one tons front and rear so I can get these rear ends(4.10's) for cheap. The back ground on my truck is it is an 86 with corporate 10's front and rear(3.42's) with the rear gear making some pretty good noise. Did Chevy ever put a 44 in the rear of their trucks? Would this be a good swap for a mild truck(future 3" suspension lift and 33 X12.5 tires)?
