More confused now! I want to drop my 2018 4WD RCSB Z71 Silverado 3" in the front. Just when I thought I had my answer with the combination of Belltech 2514 2" drop spindles combined with Belltech 25004 struts set at 1" drop, I come across the Belltech 15002 coilovers which it indicates are not only compatible with 4WD's (as there webpage does not with the spindle/strut combo) but are adjustable from a 1 to 3" drop? Why wouldn't I just go with the coilovers and set to 3" drop? Will these move the wheel off center more than the other option???? There must be an advantage to the spindle /strut for 3" front drop? Or is there? If you went with what Belltech's webpage suggests for what I want it looks to me like the coilover is their recommendation?
