♦ This installation requires a professional mechanic!

♦ We recommend that you have access to a factory service manual for your vehicle to assist in the disassem-

bly and reassembly of your vehicle. It contains a wealth of detailed information.

♦ Ensure that your work space is of adequate size and the work surface is level. Place the vehicle in neutral.

Place your floor jack under the front cross member 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 the vehicle

back in gear, set the emergency brake, and place blocks both in front and behind the rear wheels.

♦ Prior to installation, carefully inspect the vehicle’s steering and driveline systems paying close attention 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 ac-

cording 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 appro-

priate 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 Loctite

retaining 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 vehi-

cle manufacturing process will virtually ensure that some parts may seem difficult to in-

stall. 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 instal-

lation 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.
