I have em. All mine were reboxed yukons except the v6 gears I have in the rear, they looked to be precisions, but I could hardly make out the letering. I'm gonna be happy with em just like I was with my last set , till I broke em. They were yukons I bought from randys r&p. There wasnt one set that setup any better than another, all the patterns looked good after my friend and I got em shimmed, and the backlash set properly.
setup is the key!
