When I changed from 3.73's to 4.10's, I also installed the Detroit Truetrack diff's. Got a chance to put them through the paces in KY during the ice storm, working off road and in the mtn/woods, and I am very, very satisfied with the way they work. Much better than factory LS diff's.
Swapped to the 4.10's after 5 years of driving around on 35's, and it made a noticeable difference when towing, but like I said, that was on 35" tires. Put me right back to stock rpm/mph +-, and what I feel is back in the powerband for towing.
