i have read all about this great shackle flip fabrication from ORD. It claims to give you 4" of lift with stock leaf springs, right? is that 4" with the original springs, or brand new stock replacment springs(J.C.Whitney), or do you have to have to add an add-a-leaf?? id really like to get some understanding. thanx. i liked this bumper sticker i saw, "real Americans DRIVE American"
