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.

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:
   ** Neve 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. Remove the rear fender liners using a Philips screw driver. There will be 10 clips and 3 screws holding each liner in place
   

10. Support the axle with a jack.

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.
    

Strut disassembly

Mount the entire spring/strut assenship to the upper spring isolator and strut body.

Compress the spring until tensiombly in the fixture. To ease the installation of the new strut , mark the position of the top mount in relation is relieved from the strut.

Technician note:
It is important to use a spring compressor to compress the spring before removing the top mount nut.
Failure to do so may result in serious injury.

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

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

Remove the spring and strut from the fixture.

Belltech Coilover Height Setup and assembly

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

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.

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.

• Desired Lift (in) number of 25mm packers
• +3.0”: 0
• +4.0”: 1
• +5.0”: 2
• +6.0”: 3
• +6.5”: 3

Loosen the set screw on the spring perch

Belltech Coilover Height Setup and assembly

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
• +4.0”: 244/9.6
• +5.0”: 268/10.6
• +6.0”: 292/11.5
• +6.5”: 304/12.0

Technician note:
Depending on the resulting ride height, adjustments can b made using the supplied spanner wrench. It is recommended to adjust the spring perches with the coilover removed from the vehicle.

After adjusting the lower spring perch, tighten the set screw

Disassemble the OEM top mount as shown. Reference the two blue studs and the blue locator pin in the below image. These will need be removed first. The stud closest to the pin will remain in place. This is true for both drver and passenger side.

Using a vice to secure the top mount, knock the two studs out through the bottom of the mount using a hammer and punch, or an appropriate hydraulic press. Be cautious not to use excessive force to prevent from damaging the top mount.

Install the Coilover shim with the Top mount side down (this is inscribed on the part) and fasten it using the supplied button head bolts torqued to 53 ft/lbs. (Red loctite is highly recommended to prevent the bolts from loosening over time)

Assemble the Belltech coilover as shown, making sure that all parts are centered correctly and any packers are placed underneath the bumpstop and facing with the grooves downward toward the shock body. make sure to install the Belltech upper spring adapter with the spring side facing away from the top mount.

Finish assembly og the Belltech coilover by adding the Top mount/adapter combo to the top of the coilover Be sure that the thinner side of the shim will be facing towards the front of the vehicle during reassembly. This ensures installation into the vehicle in the same orientation that it was removed from. Compress the spring if necessary and tighten the Top nut completely before releasing the tension on the springs.

Strut installation

Replace the coilover on the vehicle.The small side of the shim should face the front of the vehicle

Reattach the upper strut bolts with a 15mm wrench and torque to 41 lb.ft.

Reattach the lower strut bolts with a 27mm socket and torque to 350 lb.ft.

Remove the jack that was supporting the axle.

Replace the rear fender liners using a Philips head screw driver

Finalizing the Installation

Re-install the wheels and tighten the lug nuts.

Lift the vehicle and remove the support stands.

Carefully lower the vehicle onto the flat ground.

Torque the lug nuts to manufacturer’s specifications.

Check that all components and fasteners have been properly installed and torqued.

Re-read and perform all tasks in the “Before Driving Your Vehicle” section of page 1 of your instructions.
