Are there any companies out there that make lift spring hangers? I am specifically refering to the hanger for the front eye on the rear spring of a 99 up 1500. By doing some rough calculations, it looks like I could get the lift I want by using an off the shelf 2 inch lift spring along with a shackle flip kit, if I could drop the front eye of the spring about two inches. This would keep me from needing a custom spring and would help correct some of the problems caused by the shackle flip kit.
