if you just wanna level out the truck go 5100's...just installed them,gained 2 inches and seems to ride smoother..but if you gotta off road maybe 6112 the way to go..found them on Amazon for just under a Hundo apieve.
without going through all 331 pages of this post question is 2016 sierra all terrain lower control arms are stamped aluminum....use rough country poly carbonate 2" leveling blocks which i've read in some posts wear out faster...or use the billet blocks?
