Before beginning the installation, thoroughly & completely read these instructions & the enclosed
driver's WARNING NOTICE. Affix the WARNING decal in the passenger compartment in clear view
of all occupants. Please refer to the Parts List to insure that all parts & hardware are received prior
to the disassembly of the vehicle. If any parts are found to be missing, contact SKYJACKER ®
Customer Service at 318-388-0816 to obtain the needed items. If you have any questions or
reservations about installing this lift kit, call SKYJACKER ® Technical Assistance at 318-388-0816.
Make sure you park the vehicle on a level concrete or asphalt surface. Many times a vehicle is not
level (side-to-side) from the factory & is usually not noticed until a lift kit has been installed, which
makes the difference more visible. Using a measuring tape, measure the front & rear (both sides)
from the ground up to the center of the fender opening above the axle. Record this information
below for future reference.

IMPoRTANT NoTeS:
• This lift is determined from the amount of lift to the front of the vehicle, while only lifting the
rear to a position level with the front.
• If larger tires (10% more than the stock diameter) are installed, speedometer recalibration
will be necessary. Contact your local GM dealer or an authorized dealer for details.
• After installation a qualified alignment facility is required to align the vehicle to factory
specifications.
