Introduction:
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 attention to the tie
rod ends, wheel bearing preload, pitman and idler arm. Additionally, check steering-to-frame and suspension-toframe 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
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 instructions. These are to
be used unless specifically directed otherwise. Apply thread lock 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 support 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.
Disconnect the negative battery cable when working on the vehicle.
wear safety glasses when using power tools or working under the vehicle!
Front end and head light realignment is necessary!
Speedometer and ABS recalibration will be necessary if larger tires (10% more than stock diameter) are installed.
Tire and wheel choice is crucial in assuring proper fit, performance, and the safety of
your Pro Comp equipped vehicle. For this application, a wheel not to exceed 10” in width with a
minimum backspacing of 3.25” must be used. Additionally, a quality tire of radial design, not
exceeding 35” tall X 13.5” wide (for the 5” spacer kit) or 37 tall X 13.5” wide (for the 6” coil kit)
is recommended. 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.
SPECIAL TOOLS
PLEASE REFER TO YOUR SERVICE MANUAL FOR MORE INFORMATION.
A SPECIAL REMOVAL TOOL IS REQUIRED FOR SAFE REMOVAL OF THE TIE RODS.
A SPECIAL REMOVAL TOOL IS REQUIRED FOR SAFE REMOVAL O F THE COIL SPRINGS.
THESE TOOL MAY BE PURCHASED AT YOUR LOCAL DEALER.
YOU MAY BE ABLE TO RENT ANY OF THESE TOOLS AT YOUR LOCAL PARTS STORE.

lip. Record the measurements below.
2. Ensure that your work space is of adequate size and the work surface is level.
Set the emergency brake. Place your floor
jack under the front axle and raise vehicle.
Place jack stands under the frame rails
behind the front wheel wells and lower the
frame onto the stands. Remove the jack
and place blocks both in front of and behind the rear wheels. Remove the
wheels.
3. Remove any skid plates or debris shields
from the bottom of the vehicle.

this tool, a length of chain or a flat bar
with two holes is a suitable replacement.
32. Torque the Pitman arm retaining nut to

with the head of the bolt facing the front
of the vehicle. Do not torque the cam
bolt at this time. See ILLUSTRATION 9.
49. With the vehicle on the ground, measure
from the outside edge of the tires to the
edge of the wheel well on the fenders.
Use the cam to center the axle under the
vehicle by rotating the cam until the
measurement is equal on both sides.
Torque the cam bolt to 150 ft./lbs.
50. See the driveshaft note on page 15. See
ILLUSTRATION 10.
51. With the vehicle on the ground, re-attach
sway bar end links. Torque down end
links and sway-bar bolts.
52. 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 any component. Use zip ties to secure these items
out of the way of the steering components. At full droop, cycle the steering
from lock to lock while observing the reaction of these components. Reposition
them if needed.
53. Recheck for proper installation and
torque, of all of the newly installed hardware and after any off road use.
54. Have your vehicle aligned.
55. Have your headlights adjusted.
56. After 100 miles recheck for proper torque
on all newly installed hardware.
DRIVE SHAFT NOTE: WHILE THE TRUCK IS IN THE AIR SPIN THE FRONT DRIVE SHAFT. IF THE
FRONT DRIVE SHAFT BINDS AT FULL DROOP THE JOINT CAN BE TRIMMED. YOU CAN GRIND
THE OUT SIDES OF THE CLOSE JOINTS ON BOTH SIDES. YOU WILL ALSO NEED TO GRIND THE
INSIDE OF THE FAR JOINTS ON BOTH SIDES. USE THE ILLUSTRATION TO GUIDE YOU. YOU
SHOULD HAVE THE DRIVESHAFT BALANCED BY A QUALIFIED SHOP WHEN YOU ARE FINISHED.
