Before Driving Your Vehicle:

Technician note:
Before making any adjustments to your new Belltech coilover, please be sure to loosen the set screw on the lower spring perch. 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 front 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 rear wheel lug nuts.

5. Lift the rear 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 rear 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.

11. Remove lower strut bolts with a 27mm socket

12. Remove upper strut bolts with a 15mm wrench

13. Remove the strut from the vehicle.

14. 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.

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

16. Remove top mount. You will use this with your new Belltech coilover later.

17. Remove the rubber upper spring isolator from the OE top mount. This will not be reused.

    Belltech Coilover Height Setup and assembly

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

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. Using the table below as reference, remove the main spring and slide the required packers onto the strut rod.
    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.

22. Loosen the set screw on the spring perch.

23. 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 table below. We do not recommend adjusting outside of the specified height range, as the performance of the shock may decrease greatly. Your vehicle’s exact ride heights may vary due to differences in chassis and trim levels. The perch heights depicted on our tables are a suggested starting point.
    Lift (in)| Perch Height (mm/in)
    ---|---
    +3.0”| 220/8.7
