2017 Ford F-350 | F-450 | F-550 Installation Instructions

As mentioned in the post 2017 Applications, we are continuing to confirm product fits for 2017 model applications. One of the more popular SuperSprings installations is the Ford F-Series. To help with these installations, here are the applicable SuperSprings part numbers and step-by-step instructions.

1. Jack up the rear of the truck. Support the rear of the truck on jack stands. Ensure daylight under the wheels – suspension in full droop.
2. Place PSP-11 pads on the spring-plate with smooth side facing up and cross slot to the front. Position lock down assembly U-bolt as shown below right.
3. Compress the factory overloads to clear a space for installation of the SuperSprings. Alternatively, you can remove the overload perch plastic sheaths to create more room.

4. Insert the SuperSprings so it is resting on top of the factory overload leaf and under the perches. Remove the clamps pulling down the overloads if these were used.
5. Push the SuperSprings forward so the front end of the SuperSprings is against the front hanger.

6. Using an installation tool compress the back end first of the SuperSprings down so that the rear shackle legs are located just forward of the factory spring-clip and then insert the ¾”bolt with rollers plus ¾” nut. Depending on the weight configuration of the vehicle the upper or lower bolt holes can be used. The upper bolt holes as shown below are for more lift.

7. Do the same on the front end of the SuperSprings selecting the bolt-hole in the shackle legs to give the desired lift. If necessary adjust the position of the of the rear roller to optimize the level of the truck.
8. The front end of the SuperSprings should have ¼” to ½” clearance on the front hanger.
9. If the plastic sheaths were removed from the overload perches they can now be reinstalled.

For the SSA22 or SSA25 springs on the same F-450|F-550 trucks the fit is very similar to the SSA17 or SSA26 above. Pictures of the front and rear shackle positions after installation are shown in the pictures below.

To prevent the SuperSprings from shifting after installation we install the lock-down mechanism. These ship as part of the SuperSprings kit.

Ford F-450 | F-550 trucks use any combination of the SSA17 |22 |25 |26 SuperSprings. The lock-down mechanism u-shaped cross-plate is threaded over the upturned u-bolt installed with the PSP-11 (see pictures from step 2). It is then secured in place with 3/8” supplied nuts and washers.

1. Installation of the SSA22 |25 spring follows the same logic as the installation of the double bladed SSA17 |26 springs detailed above.

2. It is important to follow this procedure to ensure that the front shackle does not end up directly below the front overload perch.
3. Ideally it positions between the front overload perch and front spring hanger.
4. Failure to do this could end up with damage to the redundant overload perch.

To prevent the SuperSprings from shifting after installation we install the lock-down mechanism. These ship as part of the SuperSprings kit.

Ford F-350 trucks uses any combination of the SSA 22 |25 SuperSprings. The lock-down mechanism is installed as described for the F-550 above.
