ok so awhile back i was watching extreme 4x4. on there they had project suburban gorilla. with the hummer body on the 87 suburban frame. for the front lift they had a coil spring setup off of a dodge. i was just curious since leaf springs are stiffer the taller you go. could this be an alternative to the leaf springs, but with better flex? i wasnt planning on doing it but the jeeps all convert to coils and maybe some burbs could to?
