INSTALLATION INSTRUCTIONS
2005-2006 KIT# NL221
WARNING
Installation of a Performance Automotive Group suspension lift kit will change the vehicle’s center of gravity
and handling characteristics both on- and off-road. You
must drive the vehicle safely! Extreme care must be
taken to prevent vehicle rollover or loss of control,
which could result in serious injury or death. Avoid sudden sharp turns or abrupt maneuvers and always make
sure all vehicle occupants have their seat belts fastened.
WARNING
Before you install this kit, read and understand all
instructions, warnings, cautions, and notes in this
instruction sheet and in the vehicle owner’s manual.
WARNING
Many states and municipalities have laws restricting
bumper heights and vehicle lifts. Consult state and
local laws to determine if the changes you intend to
make to the vehicle comply with the law.
WARNING
The installation of larger tires may reduce the effectiveness of the braking system.
WARNING
Always wear eye protection when operating power
tools.
WARNING
Before you install this kit, block the vehicle tires to prevent the vehicle from rolling.
CAUTION
Proper installation of this kit requires knowledge of the
factory recommended procedures for removal and
installation of original equipment components. We recommend that the factory shop manual and any special
tools needed to service your vehicle be on hand during
the installation. Installation of this kit without proper
knowledge of the factory recommended procedures
may affect the performance of these components and
the safety of the vehicle. We strongly recommend that
a certified mechanic familiar with the installation of similar components install this kit.
WARNING
This kit should only be installed on a vehicle that is in
good working condition. Before you install the kit, thoroughly inspect the vehicle for corrosion or deformation
of the sheet metal. If the vehicle is suspected to have
been in a collision or misused, do not install this kit.
Off-road use of your vehicle with this kit installed may
increase the stress applied to the factory components.
Failure to observe this warning may result in serious
personal injury and/or severe damage to your vehicle.
NOTE
Performance Automotive Group recommends using
the Loctite® supplied in the kit on the threads of all kit
nuts and bolts unless specified otherwise in these
instructions.
NOTE
Installation of a suspension lift will change the driveline
angles which may cause a noticeable vibration in the
vehicle. See the troubleshooting section at the end of
these instructions.
WARNING
DO NOT combine suspension, body, or other lift
devices. Use of vehicle with combined lifts may result
in unsafe and/or unexpected handling characteristics.
NOTE
Lift height may vary depending on vehicle configuration, engine size, additional accessories, the factory
suspension package, and vehicle’s condition.
