The ORD shackle flip is a replacement hanger which is stronger than stock and inverts the shackle mount . It requires you to drop the gas tank, grind the rivets off the stock hanger and bolt it to the frame. It comes in a 2" or 4" lift from the current spring height, less depending on the condition of the stock leafs. It places the shackle mount forward or backward an inch for an improved shackle angle. Its a good solution for people with the capabilities listed above who might bend a stock hanger under severe conditions or need the flip to provide less that 4".
My bracket is designed to securely bolt to the bottom of the stock hanger and provide an inverted mount from which to relocate your shackle. There is no modification to the original hanger, its constructed of stronger material than its surroundings and does not require dropping the tank. This provides 5 3/4" of lift over current spring height. Most people get an actual lift of 4 - 4 1/2" on thier springs, especially ones previously running blocks. These also relocate the shackle mount forward or backward 1" for an improved shackle postision with various length springs. A good solution for those needing the flip to provide from 4" on up.
