pletely before beginning.
2. Verify all parts have been received in this kit by
checking the parts list at the end of this document.
3. Only install this kit on the vehicle for which it is
specified. If anytime during the installation you en-
counter something different from what is outlined in
the instructions, call technical support at (877) 695-
7812.
4. Park vehicle on a clean, dry, flat, level surface and
block tires so vehicle cannot roll in either direction.
5. Measure ride height with the vehicle supporting its
own weight on level ground. To settle the suspension,
the vehicle should be driven forward at least 10 feet
immediately prior to taking these measurements. Ride

straight up (vertical) to the fender lip. Record this
measurement for all four wheels.
