 This installation requires a professional mechanic!
 We recommend that you have access to a factory service manual for your vehicle to assist in the
disassembly and reassembly of your vehicle. It contains a wealth of detailed information.
 Prior to installation, carefully inspect the vehicle’s steering and driveline systems paying close at-
tention to the tie rod ends, ball joints, wheel bearing preload, pitman and idler arm. Additionally,
check steering-to-frame and suspension-to-frame attaching points for stress cracks. The overall
vehicle must be in excellent working condition. Repair or replace all worn or damaged parts!
 Read the instructions carefully and study the illustrations before attempting installation! You may
save yourself a lot of extra work.
 Check the parts and hardware against the parts list to assure that your kit is complete. Separating
parts according to the areas where they will be used and placing the hardware with the brackets
before you begin will save installation time.
 Check the special equipment list and ensure the availability of these tools.
 Secure and properly block vehicle prior to beginning installation.
 ALWAYS wear safety glasses when using power tools or working under the vehicle!
 Use caution when cutting is required under the vehicle. The factory undercoating is flammable.
Take appropriate precautions. Have a fire extinguisher close at hand.
 Foot pound torque readings are listed on the Torque Specifications chart at the end of the instruc-
tions. These are to be used unless specifically directed otherwise. Apply thread lockretaining
compound where specified.
 Please note that while every effort is made to ensure that the installation of your
Pro Comp lift kit is a positive experience, variations in construction and assembly
in the vehicle manufacturing process will virtually ensure that some parts may
seem difficult to install. Additionally, the current trend in manufacturing of vehicles
results in a frame that is highly flexible and may shift slightly on disassembly prior
to installation. The use of pry bars and tapered punches for alignment is considered
normal and usually does not indicate a faulty product. However, if you are uncertain
about some aspect of the installation process, please feel free to call our tech sup-
port department at the number listed on the cover page. We do not recommend that
you modify the Pro Comp parts in any way as this will void any warranty expressed
or implied by the Pro Comp Suspension company.
Introduction:
PLEASE NOTE:
Due to differences in manufacturing, dimensions and inflated measurements, tire
and wheel combinations should be test fit prior to installation. Tire and wheel
choice is crucial in assuring proper fit, performance, and the safety of your Pro
Comp equipped vehicle. For this application, we recommend a 17” wheel not to ex-
ceed 9” in width with a maximum backspacing of 5” must be used.Additionally,
quality tire of radial design, not exceeding 35” tall X 12.5” wide is also recom-
mended. Please note that the use of a 35” X 12.5” tire may require fender modifica-
tion. Violation of these recommendations will not be endorsed as acceptable by Pro
Comp Suspension and will void any and all warranties either written or implied.

1. Position your vehicle on a smooth, flat, hard
surface (i.e. concrete or asphalt). Block the
rear tires and set the emergency brake.
2. Measure and record the distance from the
center of each wheel to the top of its fender
opening. Record below.
3. Place the vehicle in neutral. Place your floor
jack under the front axle and raise the vehicle.
Place jack stands under the frame rails and
lower the frame onto the stands. Remove the
jack and place the vehicle back in gear, set
the emergency brake, and place blocks both
in front and behind the rear wheels.
4. Unbolt and remove the transmission skid
plate from the vehicle.
5. Unbolt the front sway bar frame mounts

cle. It may be necessary that you slightly
raise the axle to unload the shocks for re-
moval.
7. Unbolt the front track bar from the front axle
mount and secure up and out of the work
area. Save the hardware for reinstallation.
8. Unbolt the all the ABS mounting clips from
the vehicle.

into the previously drilled 3/8” hole using the
supplied 3/8” X 2” bolt and hardware. See
ILLUSTRATION 1.

the vehicle using the previously removed OE
hardware.
20. On both sides of the vehicle, check the
routing of the brake lines and the ABS wire
harnesses. There must be no pinching,
rubbing, or stretching of either component.
Use zip ties to secure these items to the
steering components. At full droop, cycle the
steering from lock to lock while observing the
reaction of these components. Reposition
them if needed.
21. Reinstall the front wheels and lower the vehi-
cle to the ground. Torque the lug nuts ac-
cording to the wheel manufacturers recom-
mendations.
22. Reinstall the OE front track bar to the axle
mount using the previously removed OE
hardware. Torque the track bar mounting
bolt according to manufacturers specifica-
tions.

bracket (91-5841) into the original track bar
mounting pocket using the supplied 9/16” X 3
1/4” bolt and supplied spacer (90-2650). See
ILLUSTRATION 2.
