This installation requires a professional mechanic!
We recommend that you have access to a factory service manual 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, ball joints, wheel bearing preload, pitman and idler arms. 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 re-
place 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!
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 lockretaining compound where specified.
IT IS ADVISABLE THAT YOU HAVE HELP AVAILABLE WHEN INSTALLING THIS KIT. SOME COM-
PONENTS ARE HEAVY AND AWKWARD. AN ADDITIONAL SET OF HANDS IS GOOD INSURANCE
AGAINST INJURY!
Please note that while every effort is made to ensure that the installation of your Pro Comp lift kit is a positive ex-
perience, 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 ta-
pered 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.
Pro Comp Suspension products are gas-filled and are highly pressurized. Never place any Pro Comp Suspension prod-
uct in a vise or use a clamp on any Pro Comp Suspension product. Never apply heat near any Pro Comp Suspension
product, and never attempt to open or repair any Pro Comp Suspension, in order to prevent serious bodily injury or
death. Any attempt to misuse, misapply, modify or tamper any Pro Comp Suspension product voids any warranty and
may result in serious bodily injury or death.
DO NOT use impact tools for loosening or tightening fasteners. This may destroy the bolt threads.
Suspension springs are PRELOADED! The suspension spring must be compressed with the assistance of an appropri-
ate strut vise and spring compressor. The top mount must not be removed until the preload pressure is no longer pre-
sent and the spring can be moved by hand, or serious bodily injury or death may result.
After installing any Pro Comp Suspension product, the caster and camber must be checked and/or adjusted to comply
with the vehicle manufacturers specifications. Also, the (load dependent) brake compensator and the anti-lock brake
system must be checked and/or reset to comply with the vehicle manufacturers specifications. Also the headlight aim
must be checked and adjusted.
Reuse the original equipment components only if they are in good condition.
Otherwise replace them with new components. Never remove the slight film of oil on the piston rod and seal.
All mounting fasteners for struts must be securely tightened before tension is placed on the suspension system. Make
sure that the bump stop and dust cover are correctly and properly fastened.
When replacing other brands, Pro Comp Suspension shock absorbers should always be installed as a set. Installation of
shock absorbers, struts and cartridges requires special tools and expert knowledge. Accordingly, installation of all Pro
Comp Suspension products must be performed by a qualified suspension specialist.
All Pro Comp Suspension products must only be used for the specific, intended application as indicated in the applica-
tion guide. Any use of any Pro Comp Suspension product other than for it’s intended use may result in serious
bodily injury or death.
