How to Install SkyJacker 4-5 in. Standard Suspension Lift Kit w/ Shocks (07-17 Wrangler JK 4 Door) on your Jeep Wrangler

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 product, contact 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.

Driver Side Front:_______ Passenger Side Front:_______

Driver Side Rear:_______ Passenger Side Rear:_______

IMPORTANT NOTES:

• The draglink 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.
• For vehicles with 5" or more inches of lift, it is recommended to order a rear cam bolt kit for proper rear pinion angle (Skyjacker Part # CAM700). In some applications a replacement rear driveshaft may be required, Please contact Skyjacker Customer Service for more information at 318-388-0816.
