Thanks for the replies guys, It was easier to get QA1 shocks than a kit,plus I can use them on my truck later. Theyre not bottoming out, but that had crossed my mind. I should have mentioned I completely rebuilt the rear end housing and brackets so it was a baseline adjustment that got me to this point-zero preload and then one flat on the right side. I guess it needs more preload to go straight. And after looking at the pics and videos Im killing the tires at the line with 7psi, so multiple issues I guess. I'll post some pics when I can.
