It is very helpful on determining an Accurate Achieved Lift Height
Measurement.
Make sure you park vehicle on a level concrete or asphalt surface. Many times
a vehicle is not level (side-to-side) from factory, but is usually not noticed
until a lift kit has been installed which makes difference more visible. Using
a measuring tape, measure front & rear (both sides) from ground up to center
of fender opening above axle.
Important Notes
- This Suspension Lift is NOT Designed to Fit Models Equipped with Tremor Off-Road Package.
- If Larger Tires (10% More Than the OEM Diameter) Are Installed, Speedometer Recalibration Will Be Necessary. Contact Your Local FORD Dealer or an Authorized Skyjacker® Dealer for Details.
- After Installation, a Qualified Alignment Facility Is Required to Align Vehicle to OEM Specifications.
- 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.
- OEM Front Track Bar Bolt Requires 406 ft-lbs of Torque to be Installed Correctly. (After installation is complete, It is suitable to install OEM hardware & torque to 200+ ft-lbs range, then immediately take the vehicle to a shop to torque to the correct specificatrions.)
