How to Install FOX 2.5 Factory Series Reservoir Shock for 0-1.5 in. Lift - Rear on your F-150

Shop Parts in this Guide

INSTRUCTIONS

Medium-strength thread-lock (blue Loctite®) is recommended on all bolts.

1. Please read the installation guidelines for instructions on how to properly lift and secure the vehicle.

2. Record the front vehicle ride height to ensure proper lift is attained after kit is installed. You will be able to make preload adjustments if needed once the shock assembly is installed (spanner wrench required).

3. Remove both front wheels.

4. Disconnect both outer tie rod ends at the spindle steering arm for removal/ installation clearance. 5. Remove the (3) top nuts (Fig. 1) that secure the stock shock assembly to the vehicle. DO NOT remove center nut; doing so will release the spring from the stock assembly and could result in SERIOUS INJURY or DEATH!


6. Remove the (1) bolt connecting the shock to the lower control arm. (Do not discard bolt and nut, as it will be used with your new FOX coil-over assembly).

7. Remove the stock shock assembly. You may need to use a pry bar to pull on the upper control arm and lower the suspension to allow the removal and installation of your shock assembly. Be careful not to damage any brake lines or electrical wires.

8. Install the new coil-over assembly. With remote reservoir models make sure that the hoses are facing outward and towards the rear of the vehicle 


(Fig. 2). Connect the top shock hat to the vehicle using the bolts and washers provided or with Performance Series models connect the top shock hat to the vehicle using the nuts provided. Tighten all three bolts or nuts to 24 ft* lbs. (You will need to remove the outer two bolts to install the reservoir bracket in step 11.)

9. Connect the shock to the lower control arm, reusing the stock bolt and nut. Torque to factory specifications. 

Toque supplied bolt with 2.0 Performance Series shocks to 160 ft* lbs.

10. On external reservoir models install the reservoir bracket by placing it over the coil-over frame bucket. Reinstall the two bolts at the top and torque to 24 ft* lbs.

11. On external reservoir models install the reservoir onto the reservoir bracket with the supplied hose clamps.

12. Reinstall the outer tie rod ends and torque to factory specifications.

13. Check that the suspension has proper clearance by steering completely in both directions.

14. Reinstall both front wheels and torque to factory specifications.

15. Set the vehicle back on the ground and drive it back and forth several feet to allow the suspension to settle. Now measure the new ride height and make adjustments if necessary. To adjust the ride height, first lift the vehicle (refer to the INSTALLATION GUIDELINES for instructions on how to properly lift the vehicle). After properly lifted, loosen the top lock ring, and adjust the main  spring retainer. Once your height is set, retighten the top lock ring against the main spring retainer.

16. It is highly recommended that you have your wheel alignment checked.
