This body lift kit should only be installed on vehicles that are in
good working condition. Before the installation begins, the
vehicle should be thoroughly inspected for evidence of corrosion
or deformation of the sheet metal around the factory body
mounts. This body lift kit should not be installed on any vehicle
that is suspected to have been in a collision, or misused. Off
road use of you vehicle with this body lift installed may increase
the stress applied to the factory body mounts. It is not
recommended that any vehicle, with a body lift installed, be
involved in any extreme off road maneuvers such as jumping.
Failure to follow this warning may result in serious personal
injury and/or serious damage to your vehicle.
WARNING
Performance Accessories strongly discourages the use of a
suspension lift kit or any other lift device in addition to a body
lift kit. A vehicle that uses a combination of lift devices not
originally engineered to be used together may result in
unexpected and unsafe handling characteristics. Many states now
have laws restricting bumper heights and vehicle lifts. Local
laws should be consulted to determine if the changes you intend
to make to your vehicle complies with state laws.

Performance Accessories does not recommend any particular
wheel and tire combinations for use with its body lifts and can
not assume responsibility for the customers choice of wheels and
tires. Your owner's manual can be referenced 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 with an experienced local off road shop
to find what wheel and tire combinations work best with your
vehicle.
