80-97 Ford 5", 6", 7" Hanger and Rear Flip Kits

Text Tab

5", 6" and 7" Lift Rear Shackle Flip Kit replaces both the shackle hanger and the spring hanger.

Kit is designed to keep pinion angle close to stock as possible while lifting the truck.
Rear shackle flip kits position the shackle downward in order to allow the rear leaf springs to follow a more natural arc instead of fight the leaf spring under compression.
The spring hangers have three holes to aid in axle positioning.
Noticeable ride improvement.

-Remove Factory Rivets and hanger
-Install Rear Shackle Flip (there is a left and right, line holes in frame up with bracket so it runs close to parallel with the frame) secure using 1/2-1.5” bolts. It is very common to need to die grind 1 or 2 holes in the frame to line up with the bracket. Ford stamped and riveted everything so nothing is ever quite the same twice.

Do not try and install one side at a time, you must remove all hangers. After removal, install new brackets loose, push springs side to side to help set square. Install axle, loose, also push side to side to square. After all components have settled, tighten axle u bolts and then start working up to tighten the rest of the components. Failure to follow this process will result in many odd dimensions being off.

Pinion angle should be checked after installation, corrected if needed. Axle center line may have moved forward from stock. Giant lift springs will affect axle position more so and is very difficult to plan for without having parts assembled on the truck.
