JEEP GRAND CHEROKEE
2” SUSPENSION LIFT KIT
INSTALLATION INSTRUCTIONS
1999-2003
KIT# JWJ22
WARNING
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.
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
The installation of larger tires may reduce the effectiveness of the braking system.
WARNING
WARNING
Always wear eye protection when operating power
tools.
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
CAUTION
Before you install this kit, block the vehicle tires to prevent the vehicle from rolling.
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.
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.
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.
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
Lift height may vary depending on vehicle configuration, engine size, additional accessories, the factory
suspension package, and vehicle’s condition.

Adhere to recommendations when replacement fasteners, retainers and keepers are called out in the factory
service manual. When re-assembling the vehicle it is
recommended by the vehicle manufacturer that certain
fasteners are replaced in order to maintain proper
retention characteristics. This system may not include
all replacement hardware as recommended by the factory service manual. Additional replacement hardware
should be obtained prior to installation of this system to
meet the requirements of the factory service manual.
1. Disconnect both battery cables. Disconnect negative
cable first, then positive cable.

5. Measure ride height with the vehicle supporting its
own weight on level ground. To settle the suspension, the vehicle should be driven forward at least 10
feet immediately prior to taking these measurements. Ride height is the measurement from the
center of the axle straight up (vertical) to the fender
lip. Record this measurement for all four wheels.

WARNING
Retorque all fasteners after 500 miles and after off road
use. All suspension lift components should be visually
inspected and fasteners retorqued during routine vehicle servicing.
4. Install rear wheels onto vehicle with lug nuts. Snug,
but DO NOT TORQUE lug nuts.
5. Using hydraulic floor jack, raise rear of vehicle and
remove jack stands. Slowly lower vehicle onto

CAUTION
Performance Automotive Group does not recommend
any particular wheel and tire combinations for use with
its suspension lifts and cannot assume responsibility
for the customer’s choice of wheels and tires. Refer to
your owner's manual for recommended tire sizes and
warnings related to the use of oversized tires. Larger
wheel and tire combinations increase stress and wear
on steering and suspension components, which leads
to increased maintenance and higher risk for component failure. Larger wheel and tire combinations also
alter speedometer calibration, braking effectiveness,
center of gravity, and handling characteristics. Consult
an experienced local off road shop to find what wheel
and tire combinations work best with your vehicle.
6. TORQUE lug nuts to specification.
