Ok so I must admit that I tried to save some money by buying my lowering kit used. I ended up buying the rear belltech springs and shock brackets from a friend and ordering the front spindles new from belltech. I have learned from my mistake after my auto ride sensors kept poping off, I called belltech and they informed me of a new linkage kit. I just installed the linkage kit and I think I was better off before. so here is the question, I want my Denali to sit level, so do I need to screw around with the rear links more or is there something else that I didn't get? I am not sure this will matter much because of all the different rim and tire sizes but my front from ground to fender well is 33in and the rear is about 35in. I have 22's on and have about a 2in gap which is what I would like all around. (Boost I am sure you know the answer to this!) Anyone willing to give thier two cents.
