2019 SLT with the X31 package, crew cab, shirt bed, 4WD. 5.3 engine Issue is a long story- had a local shop put in a zone 2” leveling kit, they put a hole in the CV never told me, and had a huge mess under the truck with grease everywhere, this kit has new, longer half axles, fixes that, also with the vehicle level, I had sag with just loading the bed for vacation, and we bought a boat to tow and want the rake back, so no sag. Fixes that, and also like the look of it raised a bit, fixes that. Main thing is the CV boot being fixed, as I shoved some grease in it and Gorilla taped it closed for now.
