pondering the idea of doing this. wasnt there a write up on it somewhere? i was looking last night and couldnt find anything. im thinking of running the 57's with my 2.5" ORD shackle flip(mounted backwards) with a HD shackle like ORD is selling now. anyone know what kind of lift this will provide? i seem to remember most people using the 4" flip.not sure if this combo will work. i want to keep it under 4" of lift. the spring centering pin is offset correct? how far and in what direction?
