We recommend that a qualified mechanic, at a properly equipped facility, perform this installation.
It is very helpful to have an assistant available during installation.

Before Driving Your Vehicle:

It is important to double check all brake hoses, cables, and other components to be sure there is no interference. You must also check for wheel/tire to chassis/body interference. If any issues are found, review your installation instructions to be sure no steps were missed and any problems are corrected.
Make sure your vehicle is aligned immediately following installation.
Check all hardware and re-torque at intervals for the first 10, 100, and 1000 miles.
Some of Belltech’s products are designed to improve your vehicle’s off-road performance. Leveling/lifting your vehicle may result in an altered center of gravity. It is crucial to use extreme care when operating your vehicle to prevent rollover and/or loss of control.
Any changes in your vehicle’s suspension may result in transformed handleability. Please test-drive your vehicle in a remote location so you can become accustomed to the revised driving characteristics.
Perform headlight check and adjustment.
Failure to drive any modified vehicle in a safe manner may result in harm or death.
Never operate your modified vehicle under the influence of drugs, alcohol, or lack of adequate sleep.
Always wear your seatbelt.

Recommended Tools:

• Properly rated floor jack
• Support stands
• Wheel chocks
• Metric socket wrench set
• Metric wrench set
• Tape measure
• Marking Pen

Specialty Tools:

• Torque wrench up to 150ft/lbs

Technician note:
Before making any adjustments to your new  Belltech coilover, please be sure to loosen the set screw. Failure to do so will damage the threads. After the adjustments are made, you may then tighten the set screw to keep the settings in  place.

Installation Preparation:

Before beginning the installation process, measure the hub to fender heights for your vehicle and record them in the “Before” section.
After your vehicle has been modified, record the new measurements in the, “After” section. This way, you can compare the resulting height to the original. When taking the measurements, measure vertically from the center of the wheel to the inner edge of the fender.

Jacking, Supporting, and Preparing the Vehicle

1. Park your vehicle on a smooth, level, concrete or seasoned asphalt surface.

2. Block the rear wheels of the vehicle using wheel chocks. Make sure the vehicle’s transmission is in “PARK” (automatic) or 1st gear (manual).

3. Activate the parking brake.

4. Loosen, but do not remove, the front wheel lug nuts.

5. Lift the front of the vehicle off the ground using a properly rated floor jack. Lift the vehicle so the front tires are approximately 6-8 inches off the ground.

6. Place support stands rated for the vehicles weight. The stands should be positioned in the factory specified locations. (Refer to owners manual). Prior to lowering the vehicle onto stands, make sure the support stands will contact the  chassis. It is very important that the vehicle is properly supported to prevent any harm to ones self or to the vehicle.

7. Lower the vehicle slowly onto the stands.

8. Remove the front wheels.
   Technician reminder:
   Never work under a vehicle supported only by a jack. It is necessary to place support stands securely under the vehicle in the manufacturer’s specified locations unless otherwise instructed.
   OEM STRUT REMOVAL

9. Locate the three mounting bolts at the top of the strut. Remove the nuts using an 18mm wrench.

10. Remove the bottom bolts on the OE strut and lower control arm using a 15mm wrench.

11. Remove the mounting nut holding the anti-sway bar end link to the lower control arm. The nut is located on the underside of the lower control arm. This will allow the lower control arm to swing down and ease the removal of the strut.

12. Push/pry down on the control arm and remove the strut.
    Strut disassembly

13. Mount the entire spring/strut assembly in the fixture. To ease the installation of the new strut , mark the position of the top mount in relationship to the upper spring isolator and strut body. Technician note:
    The installation photograph shown was taken at a professional installation shop. It is important to use a spring compressor to compress the spring before removing the top mount bolt.
    Failure to do so may result in serious injury.

14. Compress the spring until tension is relieved from the strut.

15. Remove top mount.

16. Separate the top mount from the spring isolator using a pry tool or flat head screw driver. You will use the top mount with your new Belltech coilover.

17. Remove the spring and strut from the fixture.
    Belltech Coilover Height Setup and assembly

18. The coilover comes as shown below. Remove the nylock nut from the top of the Belltech coilover.

19. Using the table below as reference, remove the main spring and slide the required packers onto the strut rod.
    2021+ GM 1500 SUV 4WD

    Lift (Inches)| Perch height (millimeters/inches)| 15mm Packer
    3”| 186mm/7.3in| 0
    4”| 202mm/8.0in| 1

Technician note:
Belltech uses packers to maintain the correct bump stop engagement at various height ranges. Using the appropriate packer will prevent excessive body roll. If a packer is needed, according to the above charts, please place the packer on top of the vent disc, channel side down, as shown by the image to the right of this text box.

20. Confirm the vent disk is located on the strut, under the dust boot. If for any reason your vent disk is not present, please call our technical support staff before proceeding, as driving on the strut without it could cause the shock to fail.

21. Loosen the set screw on the spring perch.

22. Using the provided spanner wrench, turn the bottom spring perch to obtain desired spring perch height, measuring from the top of the perch to the center of the bushing. Find the appropriate spring perch height by referencing the tables above. We do not recommend adjusting beyond what is shown on the tables, as the performance of the shock may decrease greatly.

23. Tighten the set screw.

24. Place the Belltech upper spring seat onto the OE top mount. Belltech Coilover Height Setup and assembly Continued

25. Assemble the helper spring, intermediate ring, main spring, upper spring seat and OE top mount onto the Belltech coilover.

26. Torque the supplied nylock nut onto the strut. Reference the OE strut markings and ensure the top mount is oriented in the same fashion it was before disassembly.

27. Install the top mount into the chassis and secure using the OE nuts. Torque the nuts to factory specifications.

28. Attach the lower strut mount to the lower control arm using the supplied bolts, washers and Nylock nuts. Torque the supplied nuts to 60ft-lbs.
