1. To begin the installation of your new Scott Drake C5ZZ-5776-GTL Extended Leaf Spring Shackle Kit, jack up the rear end and place the jack stand under the frame next to the front spring attachment point.

2. Lower the rear end to relax the spring tension. Adjust the jack stand to ensure the Mustang spring has no tension. I found that the sweet spot was when the tire just began to touch the floor and the shackle began to move forward. (second notch on my stands)

3. The old shackle nuts faced in. This is the right side.

8. Place the top shackle half in, along with the nut on the inside of the Mustang frame rail. It will allow you to get the torque wrench on it later.

13. This picture shows the top nut on the inside of the drivers side Mustang shackle. I had to remove and reverse it to get the torque wrench on it later. So install it with the nut on the outside of the drivers side frame rail.

14. As you can see here, the torque wrench can not get between the Mustang fuel tank and the top shackle nut.

15. With it reversed now, the top nut is accessible as is the bottom nut.

16. This is an easy 45 minute project if you don’t have to reverse the shackle orientation. Be careful to chock the car and ensure the spring tension is relaxed before you remove the old shackles. After installing my new Scott Drake Extended Leaf Spring Shackle Kit, my new dual exhaust will clear better and the rear of the car will sit about an inch higher.
