This may have been asked a million times but i have never noticed it. Has anyone ever went with a custom coil spring instead of leafs? I think it would work real good, but it would take a hell of a coil to spring a 6000 pound vehicle and make it work right. The coils i believe might be able to give excelent flex if you could figure out the right springs. Just kind of wondering if anyone had done or seen it on 73+ chevy's???????
