Wanting to raise the rear end of my truck again. I gotta 08 Sierra rc/sb. I have a DJM Flip kit without hangers. Im currently at 6 inches or so in the back which is a 7 inch flip kit and shorter shackels. but I need to go back up. Was wondering if there can be a spacer or something I can install between the leafs and the axle. I do not have any of the factory parts so competely going back to stock is kind of out of the question. I just need about 1 to 2 inches.
