I have a 2008 RCSB Sierra with a flip kit, short shackle (1"), lift hanger set on the two up most holes (hanger is away from the bed). Does that setup give a 5" or a 6" drop? Is the Belltech 2210ff the right shock for this setup? Does anybody have the compressed and extended dimensions for this shock? Also witch Monroe shock can I use on a NNBS? The Monroe 66858 or 37078?
