Before beginning the installation, read these instructions & the enclosed driver’s WARNING NOTICE

thoroughly & completely. Also 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 disassembly of the vehicle. If any parts are found to be missing, contact SKYJACKER

about installing this product, contact SKYJACKER

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, but 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.

Driver Side Front: Passenger Side Front:

Driver Side Rear: Passenger Side Rear:

Important Notes:

• The drag link must be adjusted to center the steering wheel before the vehicle is driven. Failure to

do so will cause computer errors, odd handling characteristics, & poor performance.

• If larger tires (10% more than the OEM diameter) are installed, speedometer recalibration will be

necessary. Contact your local Jeep dealer or an authorized dealer for details.

• After installation, a qualified alignment facility is required to align the vehicle to the OEM

specifications.

Jesus Forgives, Rocks Don’t www.skyjacker.com Jesus Christ Died For You. Jesús murió por ti.
