2007 Chevrolet Silverado/GMC Sierra 2WD and 4WD Superlift 6″ Lift System Installation
Installation requires a professional mechanic. Prior to beginning, inspect the vehicles steering, driveline, and brake systems, paying close attention to the suspension link arms and bushings, anti-sway bars and bushings, tie rod ends, pitman arm, ball joints and wheel bearings. Also check the steering sector-to-frame and all suspension-to-frame attaching points for stress cracks. The overall vehicle must be in excellent working condition; repair or replace all worn parts. Read instructions several times before starting. Be sure you have all needed parts and know where they install. Read each step completely as you go.
NOTES:
• Prior to beginning the installation, check all parts and hardware in the box with the parts list below. If you find a packaging error, contact Superlift directly. Do not contact the dealer where the system was originally purchased. You will need the control number from each box when calling; this number is located at the bottom of the part number label and to the right of the bar code.
• 2007 1/2-ton GM vehicles are equipped with the StabiliTrak traction control system, commonly refered to as ESC. Premature system engagement and an associated warning light on the dash may be encountered after installing this or any other lift system. ESC function is impacted by tire size and a multitude of other factors. It will be necessary to take the vehicle to the nearest GM dealer and have the system re-programmed or “re- flashed” with the tire diameter listed in GM’s system closest to the actual diameter of the tires installed on the vehicle. Be aware, however, that the vehicle may still exhibit premature system engagement even after it has been re-programmed under certain driving conditions. Note that the ESC system will be impacted if the steering wheel is not properly centered and that the system can be disabled by depressing the traction control button located in the center stack of the dash; refer to the owner’s manual for more information about what systems are impacted by depressing the traction control button. Superlift is working on an ESC recalibration system; check the website for the latest information.
• This system will accommodate the factory wheels equipped with larger-than-stock tires as well as the factory spare tire / wheel.
• Rear lift is sold separately and includes its own instructions. Refer to those instructions before proceeding with the installation.
• A special tool is required to disassemble / assemble the front struts. Other special tools are recommended to detach/attach the pitman/idler studs. Refer to the factory service manual.
• Front end realignment is necessary.
• An arrow on diagrams indicates which direction is toward the front of the vehicle.
