Please read Instructions thoroughly and completely before beginning installation.
Installation by a certified mechanic is recommended.
ReadyLIFT® Suspension Inc. is NOT responsible for any damage or failure resulting from improper installation .
Safety Warning: Suspension systems or components that enhance the on and off-road performance of your vehicle may
cause it to handle differently than it did from the factory. Extreme care must be used to prevent loss of control or vehicle
rollover during abrupt maneuvers. Always operate your vehicle at reduced speeds to ensure your ability to control your vehi-
cle under all driving conditions. Failure to drive safely may result in serious injury or death to driver and passengers. Driver
and passengers must ALWAYS wear your seat belts, avoid quick sharp turns and other sudden maneuvers. ReadyLIFT® Sus-
pension Inc. does not recommend the combined use of suspension lifts, body lifts, or other lifting devices. You should never
operate your vehicle under the influence of alcohol or drugs. Constant maintenance is required to keep your vehicle safe.
Thoroughly inspect your vehicle before and after every off-road use.
Installation Warning: All steps and procedures described in these instructions were performed while the vehicle was prop-
erly supported on a two post vehicle lift with safety jacks. Use caution during all disassembly and assembly steps to insure
suspension components are not over extended causing damage to any vehicle components and parts included in this kit.
Included instructions are guidelines only for recommended procedures and are not meant to be definitive. Installer is respon-
sible to insure a safe and controllable vehicle after performing modifications.
ReadyLIFT® Suspension Inc. recommends the use of an OE Service Manual for model/year of vehicle when disassembly and
assembly of factory and related components. Unless otherwise specified, tighten all bolts and fasteners to standard torque
specifications listed within the OE Service Manual, or as referenced in the torque specification list provided in these instruc-
tions.
Suspension components that use rubber or urethane bushings should be tightened with the vehicle at normal ride height.
This will prevent premature wear or failure of the bushing and maintain ride comfort. Larger tire and wheel combinations
may increase leverage on suspension, steering, and related components. Due to payload options and initial ride height vari-
ances, the amount of lift is a base figure. Final ride height dimensions may vary in accordance to original vehicle ride height.
Always measure the vehicle ride height prior to beginning installation.
