Ford-RFK-004-Raw
- 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.
-Noticeable ride improvement.
Application:
-Truck: 78-97 Ford F-250/350, 92-18 E-350, 80-96 Bronco/F-150
-Spring: Kits fit the 3.5" overall width spring.
Includes:
-Includes rear hangers and hardware for rear bolting hangers to frame.
-Sold in a set to replace each side of the vehicle.
-Hangers use factory bolts to attach hanger-shackle.
Additional Information:These kits fit the 80-97 Ford F-250-350 platform, and can be modified to fit the Bronco / F-150 by re-drilling the frame mounting bolt holes.
We also offer Heavy Duty Stock Replacement Shackles and 1" Lift Shackles as well
-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.
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.

Great Product. High quality craftsmanship and parts. Functions and looks great!
Great kit that fixes the notorious door handle weakness on OSB Fords. Easy and straight forward, beginner friendly, the kit even comes with the plastic panel rivets (which you are definitely going to break taking the inner panel off). Basic tools plus a rivet gun are all you need. It's Simple!
The bracket i needed for my 1996 EB bronco arrived pretty quick. It was very well made but for the price i expected it to be a direct fit. i had trouble getting the holes to line up and ultimately had to loosely thread in the top bolts then beat the bracket into place in order to get it to line up all the way. It went on with some physical persuasion and i expect it to hold up so really no complaints. i just wish i looked a little harder before i ordered the driver side pivot arm bracket as well. hopefully i can return that.
these are as good as it gets. witness marked old hinges and new ones fell just right minor tweaking. smooth and the new bolts do make thing easy to get socket or wrench on. thanks again OBS SOLUTIONS.
Very sturdy , really like the short tucked in design.
I feel they need to add some adhesive where some of the push clips are to shallow of a hole to hold in. But quality of this is awesome
Added these (2”) to my truck along with the superduty leaf spring shackles to level my truck to match the RSK kit in the front. Leveled it out nicely. With the boomerang shackles, shackle flip kit and superduty springs it lifted the rear of the truck about 2.5inches total.
Very nice quality, fit excellent, worth waiting for them to be back in stock.
Extremely pleased of the new look set of mirrors from OBS Solutions. Cannot wait to purchase more items for my F150.
