so for a long time i have wanted to eliminate the rear lift blocks on my truck. i have recently discovered that there are kits available to do shackle flips on our trucks and that it adds about 4in of lift, by my figuring that would keep the truck at the current height while eliminating the blocks. this has been my on going goal. my question is who hear has done the flip and what changes did you see in doing it? is load capacity affected? is ride quality different? im seeking as much info on the subject as i can find. any inputs?
