Due to differences in manufacturing, dimensions and inflated measurements, tire and wheel combinations should be test fit prior to installation. Tire and wheel choice is crucial in assuring proper fit, performance, and the safety of your Pro Comp equipped vehicle. For this application, a wheel not to exceed 10” in width with a minimum backspacing of 3.25” must be used. Additionally, a quality tire of radial design, not exceeding 33” tall X 12.5” wide is recommended. Please note that the use of a 33” X 12.5” tire may require fender modification. Violation of these recommendations will not be endorsed as acceptable by Pro Comp Suspension and will void any and all warranties either written or implied.

Installation of a Performance Accessories suspension lift kit will change the center of gravity and the handling characteristics of the vehicle. Because of the higher center of gravity and larger tires, the vehicle will handle and react differently both on and off road. You must drive it 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.

Tests/Procedures: 1. Ground the Violet/Yellow wire (disarm circuit) that goes to either front door and the theft alarm module. Have the keys out of the ignition and all doors closed when grounding the wire. This should disarm the theft alarm system and prevent the theft alarm from arming. 2. Check that the interior lights do not stay on due to the wire being grounded. If they do, the illuminated entry relay will need to be removed or another method of disabling the theft alarm will have to be used. 3. Another method if the theft alarm module is faulty would be to disconnect the module and replace the Powertrain Control Module (PCM) with a new one.
