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, 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.

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

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