» Front DIsassembly

1. Park the vehicle on a clean, flat surface and block the rear wheels for safety.

2. Raise the front of the vehicle and support with jack stands at the frame rails.

3. Remove the front wheels.

4. Disconnect the driver’s and passenger’s side front sway bar links from the lower control arm. Figure 1A Another option is to remove the 2 bolts and 2 nuts attaching the sway bar to the frame on the driver and passenger while still leaving the sway bar links attached to the lower control arm Figure 2B. Allow the sway bar to rest out of the way for the front end disassembly. Thread locker will be required if disassembled from the mounts to the frame.
   Step 4 Note:
   Do not use power tools to remove the stabilizer bar link nut to the lower control arm. Damage to the stabilizer bar link ball joint or boot may occurComplete this portion of the installation on one side at a time

5. Disconnect the front brake line and ABS line from the steering knuckle. Figure 2

6. Disconnect the front brake line from the frame. Figure 3

7. Remove the steering tie rod end nut from the tie rod end at the steering knuckle. Use a tie rod end remover to dislodge the tie rod end from the knuckle. Be careful not to damage the boot. Figure 4 Remove the tie rod end from the knuckle.

8. Remove the upper ball joint nut and thread back on a couple of turns by hand. Use a ball joint separator tool to dislodge the upper ball joint from the knuckle (204-592 tool recommended). Be careful not to damage the boot. Figure 5 Remove the nut and remove the ball joint from the knuckle. Allow the knuckle to rest back away from the front strut.

9. Optional: Remove the CV retaining nut. Figure 6

10. Optional: Use an air hammer to dislodge the CV shaft from the hub Figure 7. This step is optional, but will make it easier to remove the strut from the vehicle.
    Step 10 Note:
    Be careful not to hit the threads on the CV shaft A punch and hammer can also be used to dislodge the CV shaft from the hub.

11. Support the lower control arm with an appropriate jack. Remove the lower strut mount nuts at the lower control arm. OPTIONAL: This can be done to make the strut easier to be removed. Use an air hammer to dislodge and remove the strut studs in the lower strut mounts Figure 8.
    Step 11 Note:
    Be sure to support the lower control arm / knuckle assembly when removing the strut.
    Step 11 Note:
    A punch and hammer can also be used to dislodge the studs from the lower strut mount.

12. Remove the three upper strut mounting nuts at the frame. Figure 9 DO NOT remove the center strut rod nut.

    Step 13 Note:
    Be sure to support the lower control arm / knuckle assembly when removing the strut. » Strut sPacer InstallatIon

14. Remove the pin in the strut top hat Figure 11.
    Step 14 Note:
    Coil Spring is under extreme pressure. Improper removal/installation of coil spring could result in serious injury or death. Use only a high-quality spring compressor and carefully read and follow the manufacturer’s instructions.

15. Place alignment marks on the upper top hat, isolator, spring, strut body and lower coil seat for reference when the strut is assembled Figure 12. Spring rotation is critical and the spring position must not change relative to the lower strut body alignment marks, just rotate the metal top hat and not the spring isolator.

16. While still using the strut compressor, compress the coil spring and remove the upper strut nut Figure 13. Step 16 Note:
    Coil Spring is under extreme pressure. Improper removal/installation of coil spring could result in serious injury or death. Use only a high-quality spring compressor and carefully read and follow the manufacturer’s instructions.

17. Remove the lower strut assembly from the strut compressor, the top hat and spring can remain in the strut compressor.

18. Remove the strut washer, dust boot, bump stop, plastic or metal cap, and the lower spring seat from the strut body Figure 14A & B. After fully disassembled the strut should be the same as Figure 14D.

19. Install the provided preload spacer ring on the strut body such that the groove in the preload spacer goes over the snap ring on the strut body Figure 15.

20. Reinstall the lower coil seat, plastic or metal cap, bump stop, and dust boot in reverse order Figure 16A & B.

21. Install the provided bump stop extension on top of the bump stop followed by the strut washer as shown in Figure 17.

22. Reassemble the lower strut assembly with the top hat and spring. Due to lower bar pin angle in the strut, the top plate of the strut assembly must be rotated 180 degrees. Figure 18. This will allow the lower bar pin to reassemble in the lower control arm smoothly. Spring rotation is critical and the spring position must not change, just rotate the metal top hat and not the spring isolator.
    Step 22 Note
    More preload will need to be put into the spring to reinstall the strut nut.

23. The studs will need to be trimmed for the strut spacer to be installed. The studs must be 13/16″ tall from the mounting surface. Install the strut spacer and make sure the studs sit flush / to barely below the surface. Do not trim the studs too short or the prevailing torque nut will not “lock” Figure 19.
    Step 23 Note:
    IMPORTANT!
    FAILURE TO FOLLOW STUD TRIMMING STEP WILL RESULT IN STRUT SPACER DAMAGE.

24. Install the shorter 10mm bolts through the hex holes on the bottom of the front strut spacer (05113). The front strut spacer will have a slight taper to it. Attach strut spacer on top of the factory strut with high side of the taper towards the outside of the vehicle. Tighten to the top plate using the provided 10mm washers and provided 10mm nuts to 35 ft-lbs. In Mid-year 2022 the thread pitch for the upper strut nuts changed. Verify the correct thread pitch is being used between a coarse thread 10mm-1.50 thread in 2021-Mid-year 2022 and a fine thread 10mm-1.25 starting in Mid-year 2022. DO NOT EXCEED 35 ft-lbs when tightening the spacer to the strut.
    Step 24 Note:
    Hardware for the strut spacers is in Bolt Pack 368.
    Use a 17mm “thin walled” / “chrome” socket to tighten the spacer to the strut.
    The “Made in the USA” / 05113 is on the high / thick side of the taper and will face outwards towards the tire when installed.

25. Reinstall the strut assembly into the upper frame mount by aligning the studs in the new spacer with the original mounting holes and aligning the lower studs with the mounting holes in the lower control arm Figure 21A. It is important to note that the outer winding of the coil spring must face the outside (tire side) of the vehicle Figure 21C & D. This is to ensure proper “bowing” of the coil spring. Verify the coil spring position and adjust accordingly using a strut compressor.
    Step 25 Note:
    Hardware for the strut spacers is in Bolt Pack 368.
    The thick part of the spacer will be pointing towards the out side of the vehicle as shown in Figure 20C.
    The studs will be just at the surface for the frame mount when installing the strut into the vehicle. A magnet can be used to pull the studs up. This is done to make installation easier when the lower barpin studs are not removed.
    Driver Side: The lower end tip faces front of the vehicle. Figure 21B
    Passenger Side: The lower end tip faces rear of the vehicle. Figure 21B
    

26. Loosely fasten the strut to the upper frame mount with the provided 10mm nuts and 10mm washers.

27. Loosely fasten the strut to the lower control arm replacing the nuts onto the studs. If the studs were removed earlier for ease of removal of the strut, replace the studs and nuts.

28. Tighten the upper frame mount nuts to 35 ft-lbs. DO NOT EXCEED 35 ft-lbs when tightening the spacer to the strut.

29. Tighten the two lower strut stud / nuts to 66 ft-lbs. If the lower strut studs were removed, ensure that the stud is fully seated into the lower bar pin on the strut after torquing.
    » Front InstallatIon

30. If installing recommended Zone Upper Control Arms (ZONF2302), do so at this time. Follow instructions provided with the upper control arms for installation.

31. With the strut installed, reconnect the knuckle to the upper ball joint. Replace with factory hardware Figure 22A. While connecting the upper ball joint, be sure that the CV shaft properly aligns into the hub Figure 22B. Torque the upper ball joint nut to 46 ft-lbs.

32. Be sure the CV is properly seated in the hub and replace with the factory CV axle nut. Torque the CV axle nut to 221 ft-lbs.
    Step 32 Note:
    CV axle nut may need to be torqued on the ground with the weight of the vehicle.

33. Reconnect the brake line bracket and ABS line to the steering knuckle and frame with the factory bolts. Torque hardware to 159 in-lbs.

34. Attach the steering tie rod end to the steering knuckle and replace with factory nuts. Torque to 46 ft-lbs.

35. Complete installation of strut spacers on both sides of the vehicle.
    » FInal Front InstallatIon

36. With both sides complete, reconnect the sway bar links to the lower control arm and replace with factory hardware. Torque to 111 ft-lbs. If the sway bar was removed from the mounts to the frame, replace the 2 factory bolts and 2 factory nuts to the mounts in the frame. Thread locker must be used on the bolts if removed from the mounts to the frame.

37. Check all brake / ABS lines for proper routing and clearances.

38. Install the wheels and lower the vehicle to the ground. Torque lug nuts to 100 ft-lbs in a crossing pattern.

1. Block the front wheels for safety.

2. Optional: Disconnect the track bar from the rear axle mount. Save hardware.

3. Raise the rear of the vehicle and support with jack stands under the frame rails just ahead of the lower control arm mounts.

4. Support the axle with a hydraulic jack.

5. Remove the wheels.
   Complete this portion of the installation on one side at a time

6. Remove the screws and screw clips attaching the rear inner fenders to the vehicle Figure 15A & B. Remove the inner fender from the vehicle. This will allow access to the rear upper strut mounts.

7. Make sure the rear axle is supported. Remove the three upper strut mounting nuts at the frame. Figure 15 DO NOT remove the center strut rod nut. Discard the nuts.

8. Remove the lower strut mount bolt from the axle end. Figure 17

9. Remove the strut assembly from the vehicle Figure 18. » Rear InstallatIon

10. Use a strut compressor to compress the coil spring slightly. The strut will not need to be disassembled. Figure 20.

11. Rotate the metal top hat 180 degrees from its initial position. This will allow the new strut spacer to mount to the factory upper strut mount. Remove the strut from strut compressor for strut spacer installation.

12. The rear studs will need to be trimmed for the strut spacer to be installed. The studs must be 1″ tall from the mounting surface Figure 19.

13. Install the longer 10mm bolts through the hex holes on the bottom of the rear strut spacer (05115) Figure 21A. Attach strut spacer on top of the factory strut Figure 21B. Tighten to the top plate using the provided 10mm washers and OE strut nuts to 35 ft-lbs as shown in Figure 21C. DO NOT EXCEED 35 ft-lbs when tightening the spacer to the strut.
    Step 13 Note:
    Make sure the OE studs do not stick past the top of the strut spacer.
    Hardware for the strut spacers is in Bolt Pack 368.
    The rear strut spacers are not tapered and can be installed any direction on the strut.

14. Reinstall the strut to the vehicle, noting that the strut will be installed 180 deg opposite as it was removed.

15. Use the provided 10mm nuts and 10mm washer to attach the strut to the frame mount Figure 22.
    Step 15 Note:
    Hardware for the strut spacers is in Bolt Pack 368.

16. Attach the strut to the axle using an OE lower strut mount bolt and nut Figure 23. Reservoir will still face forward as it did from the factory. Post-Installation Warnings
    1. Check all fasteners for proper torque. Check to ensure for adequate clearance between all rotating, mobile, fixed, and heated members. Verify clearance between exhaust and brake lines, fuel lines, fuel tank, floor boards and wiring harness. Check steering gear for clearance. Test and inspect brake system.
    2. Perform steering sweep to ensure front brake hoses have adequate slack and do not contact any rotating, mobile or heated members. Inspect rear brake hoses at full extension for adequate slack. Failure to perform hose check/ replacement may result in component failure.
    3. Perform head light check and adjustment.
    4. Re-torque all fasteners after 500 miles. Always inspect fasteners and components during routine servicing.

17. Tighten the upper frame mount nuts to 35 ft-lbs. DO NOT EXCEED 35 ft-lbs when tightening the spacer to the strut.

» Wheel / tIre FItment notes

1. Although 37″ x 12.50″ will work at ride height, the tires will still contact the front body mount (Figure A & B) and possibly rear inner fender (Figure C) through wheel travel and steering lock to lock. If running this size tire and using the full suspension travel, these areas must be addressed.
   Fitment Note:
   All Wheel / Tire fitment information is with the front and rear intrusion beams removed same as how a Sasquatch model has them removed.
   Tire diameter and width will vary based around tire brands and wheels used. Tire side profile will also affect clearance to the stock UCA and sway bar.

2. A maximum of 35″ x 12.50″ tire on a 17×8.5, 17×9, 18×8, 18×9, or 20×9 on 5.5″ to 5″ back spacing will clear through wheel travel and is recommended for best performance and minimal rubbing Figure D.

3. A 275/70R18 is recommended on 18″ Outer Banks wheels or other wheels with similar back spacing (6.375″ BS). Wider tires may rub the sway bar.
   4. A 275/80R17 is recommended on 17″ Black Diamond wheels or other wheels with similar back spacing (6.5″ BS). Wider tires may rub the sway bar.
   5. A 285/70R17 is recommended on 17″ Badlands wheels or other wheels with similar back spacing (6.75″ BS). Wider tires may rub the sway bar.
   6. A 315/70R17 is recommended on 17″ Sasquatch wheels or other wheels with similar back spacing (6″ BS).
   7. A maximum of 35″ x 11.20″ (285mm width tire) tire on a 17×8.5, 17×9, 18×8, 18×9, or 20×9 on 6″ back spacing will clear through wheel travel and is recommended for best performance and minimal rubbing. Wider tires / more aggressive sidewall tires than 285mm width (295-315mm widths) will rub the sway bar and / or UCA on a 6″ back space wheel.
   20″: 285/65R20, 285/60R20
   18″: 285/75R18, 285/70R18
   17″: 285/75R17, 285/70R17

4. 35″ x 12.50″ tire on a stock 17″ Badlands, 17″ Black Diamond or 18″ Outer Banks wheel will NOT clear through wheel travel and will rub on the stock UCA when turning Figure E and the sway bar. Any other stock wheel or aftermarket wheel with 6.75″ to 6″ back spacing will have similar rub issues on a 35″ x 12.50″ tire.
