  1. Can’t find a fix for the level kit installed on my at4, now I’m being told don’t run 4 auto or possible cv damage?!? Nobody sells a current diff drop spacers kit. I’m ordering the supreme suspension # a4302 kit for years 01-08 Silverado/Sierra. Anyone got any fixes other than buying a entire new suspension. Still on my stocks 18” factory wheels. After the diff drop I’ll add 22” 12.5x10-18 with 33” tires. Thanks guys
