I am looking to put this kit on my 2015 SV 2wd. I already have a leveling kit installed on the stock suspension using a spacer in the front and larger brackets in the rear. If I put this kit on front and rear of the truck will I need to replace the larger brackets in the back with the stick brackets? Will I still need the spacer in the front to fit my 31 in tires? And will I need to buy a new control arm just to fit this kit in my truck? Also if anyone has any experience with this kit that can advise on their install process and how it went and if they had any issues that would be great!
