Vehicle Handling and Off-Road Performance
Some of Belltech’s products are designed to improve off-road performance. However, leveling/lifting your vehicle may alter its center of gravity. Exercise extreme care when operating your vehicle to prevent rollover and/or loss of control.
Driving Characteristics and Safety
Any changes in your vehicle’s suspension may affect its handleability. Test-
drive your vehicle in a remote location to become accustomed to the revised
driving characteristics. Perform a headlight check and adjustment.
Never operate your modified vehicle under the influence of drugs, alcohol, or lack of adequate sleep. Failure to drive any modified vehicle in a safe manner may result in harm or death.

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
-
Park your vehicle on a smooth, level, concrete or seasoned asphalt surface.
-
Block the rear wheels of the vehicle using wheel chocks. Make sure the vehicle’s transmission is in “PARK” (automatic) or 1st gear (manual).
-
Activate the parking brake.
-
Loosen, but do not remove, the front wheel lug nuts.
-
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.
-
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 import-ant that the vehicle is properly supported to prevent any harm to ones self or to the vehicle.
-
Lower the vehicle slowly onto the stands.
-
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.

-
Remove the 3 flanged nuts that secure the top of the strut to the chassis.
-
Push the lower control arm down until the strut is able to clear the control arm.
-
Drop the old strut out of the strut tower
-
Carefully 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.
-
Compress the spring until tension is relieved from the strut.
Technician note:
The installation photograph shown was taken at a professional instal-lation 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. -

2021+ GM 1500 SUV 2WD/4WD
Lift (Inches)
| Perch height (milli- meters/inches)|
15mm Packer
2”| 170mm/6.7in| 0
3”| 190mm/7.5in| 1
3.5”| 200mm/7.9in| 2
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.
-
Confirm the vent disk is located on the strut, under the dust boot. If for any reason your vent disk is not pres-ent, please call our technical support staff before proceeding, as driving on the strut without it could cause the shock to fail.
-
Loosen the set screw on the spring perch.
-
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 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.
