KIT INSTALLATION
2019+ GM1500 2WD/4WD 0-3.5" Lowering Coilover
WE RECOMMEND that a qualified mechanic, at a properly equipped facility, perform this installation.
WE RECOMMEND that the installation be performed on a firm, flat, and level surface such as seasoned asphalt or concrete.
The use of safe and proper equipment is very important!
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.
KIT PRERPERATION
a) Before beginning the install process, measure the hub to fender heights for your vehicle so you can compare the resulting height to the original. Measure vertically from the center of the wheel to the inner edge of the fender. Record results here.

1) JACKING, SUPPORTING AND PREPARING THE VEHICLE
a) Block the rear wheels of the vehicle with appropriate wheel chocks. Make sure the vehicle's transmission is in "PARK" (automatic) or 1st gear (manual). Activate the parking brake.
b) Loosen, but DO NOT REMOVE the front wheel lug nuts.
c) Lift the front of the vehicle off the ground using properly rated floor jack. Lift the vehicle so that the front tires are approximately 6-8 inches off the ground surface.
d) 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.
e) Lower the vehicle slowly onto the stands, checking that they properly and securely contacting the frame rails as described above before placing the vehicles weight completely on them.
f) Remove the front wheels.
!SAFETY REMINDER! Check for safe vehicle stability before proceeding under the
vehicle to begin the following procedures. Never work under a vehicle supported by ONLY a jack. Always use properly rated support stands to support the vehicle.

2) OEM Strut Removal
a) Locate the three mounting bolts of the strut top mount and remove the nuts using a 18mm wrench. (Photo 1)
b) Locate bolts on the underside of the lower control arm that hold the strut to the lower control arm. (Photo 2)
c) Remove two bottom mounting nuts of the spring/strut
1
assembly. (Photo 3)
d) Remove the mounting nuts holding the sway bar end link to the lower control arm. This will allow the lower control arm to swing down and make the removal of the strut easier. The nut will be on the underside of the lower control arm. (Photo 4)
e) Push the lower control arm down to provide enough
room to pull the OE strut from the vehicle.

3) OEM Strut Disassembly
!CAUTION! The coil spring is held in place under ex-
treme compression. Belltech recommends the use of a
heavy duty spring compressor suitable for truck
springs to perform the following steps. If unsure of
your spring compressor capabilities, take your struts to
a professional installer. Use caution during the follow-
ing steps to avoid personal injury and/or damage to the
vehicle.

a) Mark the orientation of the strut top mount relative to the
strut body with a paint pen.
b) Mount the strut assembly into a spring compressor and compress the spring to alleviate the tension on the strut (Photo 5)

c) Locate the top nut of the strut assembly and loosen (DO NOT USE AN IMPACT) the nut with a 18mm wrench. (Photo 6)
d) Remove the nut and decompress the spring. (Photo 7)
Note: Support the strut as the spring decompresses as
the strut can slide out.
e) Remove the top mount from the spring isolator as this
6
will be the only part reused. All other parts can be dis-
carded. (Photo 8)
Note: A screwdriver or pry tool may be useful to sepa-
rate the top mount from the isolator.
4) Coilover Assembly/Setup
a) The coilover comes as shown in photo 9. Remove the nylock nut from the top of the Belltech coilover.
b) Using the vehicle height table below for your application,
7
remove the main spring and slide the required packers
onto the strut rod. (Photo 10)
Note: Ensure that the vent disk is on the strut under the
dust boot. If the vent disk is not present, please notify
our technical support staff as driving on the strut without
this disk could cause the shock to fail.

f) Push the OE top mount into the Belltech upper spring seat. (Photo 11) Note: This should require no pressure
g) Reassemble the main spring and upper spring seat with the OE top mount onto the Belltech strut. (Photo 12)
h) Using the nylock nut supplied that came on the strut, torque the nut down. Reference the OE strut markings
11
and ensure that the top mount is in the same orientation
as when disassembled from the OE strut. (Photo 13)
4) Coilover Installation
a) Install the Belltech coilover into the frame strut tower. Secure the top mount with the OEM flanged nuts and torque to factory specifications. (Photo 14)
b) Attach the lower strut mount to the lower control arm us-
ing the supplied bolts, washers, and Nylon-lock nuts in
12
hardware kit 150210E-777. (Photo 15)
Note: Unless otherwise stated reuse the OE bottom
strut clips and OE bolts.
c) Reinstall the sway bar end link nut in reverse order of removal.
5) Finalizing the Installation
a) Re-install the wheels and torque to OEM specifications.
b) Check that all components and fasteners have been
13
properly installed and torqued.
c) Lift the vehicle and remove the support stands. Carefully lower the vehicle to the ground.
d) Check brake hoses, cables, and other components for possible interference.
e) Check for wheel/tire to chassis/body interference.
f) Test-drive the vehicle in a remote location so that you
can be accustomed to the revised driving characteristics
14
and handling. Be aware that the vehicle will handle sub-
stantially different.
g) Check all of the hardware and re-torque at intervals for the first 10, 100, and 1000 miles.
NOTE: Front end alignment is required immediately following the installation.
