78-97 Ford 4x4 2" & 4.5" Rear Shackle Flip Kits

78-97 Ford 4x4 2" & 4.5" Rear Shackle Flip Kits

Installation:

- 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.

Beautiful!

As expected Sky’s delivered another very well designed and built part. As mentioned in the notes it will move your axle forward a bit but I’ll take that over super tall blocks any day!

Work on Vans too

Used on my 2010 E350. The 4.5" kit gave me 3.5" of lift. Very pleased with the results. Had to use a 6deg. shim to correct the differential angle. Very good product. Easy to install.

Awesome, glad to hear it! We will be making an E350 section on the website as all the rear suspension parts for the OBS F350 work on the E350 as well and within the next year we hope to develop some kits for the front as well.

Why can't they get it right?

All these warnings about moving the axle forward, changing pinion angles, I just can't understand why they design something that doesn't just bolt on and work

My truck is completely stock and the shackle flip moved my axle 2 inches forward and made my pinion angles not drivable.

Now I have to do a whole bunch of other custom work to make the truck usable again. Sure it's a quality product but there's no research and development behind it.

We apologize for any inconvenience you've experienced. We've been working on improving our website so customers are able to find the info they are looking for. We have added easy access tabs with clearer instructions. Per the Installation tab, it reads: 'Pinion angle should be checked after installation, corrected if needed. Axle center line may have moved forward from stock.'

Perfect fit!

I bought the 4.5" shackle flip to go with my 5" front shackle reversal and used a 1/2" lift block and my 96 f250 is perfectly level. I avoided using a sketchy big lift block this way plus it rides so much better! I will say though the 4.5" flip pushed the wheel very noticeably forward in the wheel well so I had to custom fab the lift blocks to move the axle 1 1/4 inch rearwards on the springs, no big deal though. Great product!

6 inch Ford leaf spring hanger kit

I cannot emphasize enough the quality of the parts in this kit. Everything fit perfectly. I was able to install this in one afternoon. I no longer have the stupid rear lift blocks and the truck rides amazing. I would highly recommend any parts from Sky Offroad Design.
