INSTALLATION INSTRUCTIONS QA1 Hx01, Hx02, Hx03, 1979-2004 Mustang Struts CC110, CC112, CC114, 1979-2014 Caster-Camber Plates

· Floor Jack

TOOLS AND SUPPLIES REQUIRED

· Torque Wrench

· T-15 Torx Bit

· Jack Stands

· 24mm or 15/16″ Crows Foot Wrench · Lug Wrench

· Spring Compressor (Optional) · Basic Tool Set

PRE-INSTALLATION NOTE:
’79-`04 struts were designed for a 0″-2″ lowered ride height. Caster-Camber plates were designed for additional negative Camber and increased positive Caster for better handling performance.
QA1 struts can be used as coil-over struts or just as struts with a factory type spring (except S197 vehicles-must use coil-overs), however, the use of QA1 lower control arms or QA1 k-member will require coil-overs as the QA1 control arms and QA1 k-member have no provision for a factory style spring.
QA1 struts were designed to work with QA1 caster-camber plates and will not work with the factory upper strut mount. The installation process for Fox Body and SN95 cars is slightly different. Find your specific year range in the following instructions.

REMOVAL

1. Start your installation by inspecting your chassis. Look for worn/deteriorated bushings, ball joints, etc. If anything is worn, plan to replace during this installation.
2. Above the 24mm nut on the existing strut rod, there are two flat spots to enable the use of an adjustable wrench to keep the piston rod from turning. Loosen the 24m nuts on the upper end of the piston rods where they come through the caster/camber plates. Do not remove the 24mm nuts at this time.
3. Jack the car up and ensure the frame is set in place securely on jack stands. See your owner’s manual for proper jacking techniques. Remove the wheels.
4. Removing the brake caliper from the knuckle assembly and hang the caliper by something other than the brake line. Damage to the brake line can occur if the caliper is hung by the brake line.
5. Position the floor jack under the ball joint cup. Jack the A-arm up just enough to take the load off of the strut and spindle, without raising the car off the jack stands. This will retain the factory spring in its location.

NOTE: The factory spring will need to be removed from the vehicle (only if ’79-’04 cars and using coil-overs). To do this, first complete the strut removal process and slowly lower the control arm to take the pressure off of the spring. CAUTION: THE SPRING CAN BE UNDER TREMENDOUS PRESSURE AND IT IS CRITICAL TO USE CAUTION WHEN REMOVING. A spring compressor is recommended.
6. Loosen and remove the two nuts and bolts that attach the strut to the spindle knuckle. Remove the 24mm nut at the top of the strut and remove the strut assembly.
CASTER-CAMBER PLATE INSTALLATION:
NOTE: Reference the caster-camber plates for the year range of vehicle being worked on (below):

1994-2004 SN95 (Caster-Camber p/n CC114)

1. Identify the right (passenger)/left (driver) caster-camber plate and their orientation. 2. Remove the three nuts holding the plates together (#9), noting the location of each plate on the vehicle. 3. Using the correct right or left lower plate, insert the plate studs down into the top of the existing three factory holes,
center the studs in the slots and mark the fourth (threaded) hole onto the chassis. (Figure 1, 2, 3) 4. Drill the marked hole to 3/8″.

STRUT INSTALLATION-
1. In preparation of installing the strut, remove the strut adjustment knob using a Torx T-15 tool. (Figure 4)
NOTE: For 1979-2004 cars using a factory style spring and running the QA1 strut as a non coil-over strut, install the shown spacer and continue to install step 10. (This spacer is not used if the strut is used as a coil-over)

Figure 4

Figure 5

2. Remove the wiper boot from the top of the black threaded area of the strut. (Figure 5)
3. Thread the coil-over lock nut (#7) down the body of the strut with the shouldered end UP.
4. Thread the spring seat nut (#1) down the body of the strut with the shouldered end up. This spring seat may have a threaded hole but is NOT used with this installation.
5. Coat one side of the stainless steel spring seat washer (#2) (included with each strut) with Permatex® Anti-Seize Lubricant.
5 9919-294

Rev. 05012024

6. Reinstall the wiper boot ensuring the boot is seated in the groove of the threaded portion of the strut.
7. Install the spring onto the strut, followed by the upper spring seat (#3).
8. Install the 1″ I.D. thrust bearing kit onto the top of the upper spring seat to create a “bearing sandwich”. (#4, #5, #4)
9. Install the bearing retainer (#6) onto the strut.
10. Place the strut rod through the caster camber plate and install one SG104 spacer with the narrow end facing down, followed by the strut retaining nut. (Figure 6)

Figure 6

11. Reinstall the adjustment knob onto the strut rod. Torque to 10 inch lbs.

12. Position the spindle knuckle into the bracket on the strut. ’79-’93 Fox body spindles have two different width spindles. QA1 strut mounts are wide to fit the early and 4 cyl. spindles. If installing on the narrow V8 or SN95 spindles, use the included spacers on each side of the spindle to fill the gap. (Figure 7)

13. Install the two spindle mounting bolts and nuts. Torque to 148 lb. ft.
14. Re-install the ABS wire (if equipped) with zip tie to the brake line and sway bar end-links to the strut housing if removed. SN95 uses the spindle bolts to re-mount these items.
15. Reinstall the brake caliper and wheel. Torque all nuts and bolts to factory specification.
16. Torque the upper strut mount nut using a 24mm crows foot wrench to 45 lb. ft.
17. Repeat the entire removal and installation procedures for the other side of the vehicle.
18. Take the car to a reputable alignment shop and have the car aligned.
Front Strut Valving Adjustments
QA1 struts have 18 damping settings adjusted at the knob on top of the strut. The knob set fully counter-clockwise is the softest setting -start your adjustments from this point. Do not force the knob past the 18th click or it could cause damage to the valving. Single adjustable struts soften or firm the rebound valving while having a fixed compression. Double adjustable struts have independent compression and rebound adjustments. The function of the adjustment knob on Single Adjustable and Double Adjustable struts is as follows:
SINGLE ADJUSTABLE- Turn the adjustment knob counter-clockwise until the knob stops- This is the softest setting. Turn the knob clock-wise to firm the rebound.

Press Knob DOWN to adjust Compression.
9919-294

Pull Knob UP to adjust Rebound.
7

DOUBLE ADJUSTABLE- Pressing the adjustment knob DOWN will adjust the Compression valving of the strut. Pulling the adjustment knob UP will adjust the Rebound valving. Out of box, the strut should be at zero compression and rebound setting, or both adjustments turned counterclockwise to stop. From the zero setting with the knob in the Compression position (pushed down), adjust clockwise to the desired setting. The Rebound setting will remain in the zero position. To adjust Rebound, pull the knob up to the Rebound adjust position and adjust clockwise to the desired setting. Either setting can now be adjusted up or down from the initial setting. When in doubt, turn the Compression to zero and then Rebound to zero and readjust.
