Installation Instructions:
 1.	Before beginning, read instructions carefully and completely.
 2.	Jack up the front of vehicle enough to lift the tires off the ground as per manufacturer recommendation and support with jack stands on the frame.   
 3.	Remove the front tires and skid plate (12 mm socket) Perform install on one side of vehicle at a time.
 4.	Using a 19 mm socket, remove the bolt from the sway bar end link at the lower control arm.
 5.   Loosen the front and rear lower control arm bolts using a 24 mm socket**DO NOT REMOVE BOLTS OR ALIGNMENT CAMS**
 6.	Loosen and remove the two 22 mm bolts that connect the lower ball joints to the spindle-USE CAUTION AS THE LOWER COTROL ARM WILL DROP DOWN AS SOON AS YOU REMOVE THE LOWER BALL JOINT BOLTS.
 7.	Using a 14 mm wrench, remove the 4 upper strut mounting nuts.	
 8.	Using a 22 mm socket, remove the large lower strut assembly bolt: 
 9.	Remove the entire strut assembly. You should now be able to access the upper strut plate (top of the strut).
10.	Install one of the steel spacers provided on top of the strut with the notch side facing out. It will only fit one way! Re-use the factory stock nuts on the factory strut studs.  Torque nuts to 25 ft. lbs.
11.	Re-install the strut assembly back in the upper strut tower the same direction it was removed and start the Nylock nuts on the four studs that extend thru the tower.  DO NOT TIGHTEN NUTS YET.
12.	Using a bottle or floor jack, raise the lower control arm enough to re-install the lower strut assembly bolt and nut. DO NOT TIGTHEN NUT YET!!
13.	Continue raising the lower control arm up until you can re-connect the lower sway bar end link and tighten to 35 ft. lbs.
14.	Finish tightening the four upper stud nuts and torque to 25 ft. lbs. Also tighten the lower strut bolt/nut to 175 ft. lbs.
15.	Install the two 22 mm lower ball joint bolts, beginning with the rear bolt first. It is easier to line the rear bolt up with the spindle and torque to 185 ft lbs
16.	Install the front tire.  Repeat the spacer installation procedure on the other side of vehicle.
17.	After both sides are complete, carefully lower the vehicle to the ground and torque lug nuts to factory OEM specs (85-90 ft. lbs) Re-install skid plate
18.	ALIGN THE VEHICLE: Re-aligning the vehicle must be done to allow the front suspension to relax to its proper ride height (the front tires will be slightly toed-in which will cause excessive tire wear and will force the front of the vehicle to sit too high).  Re-aligning the vehicle is required with any lift/leveling kit.
WARNING!  Installation of this kit should be by a certified mechanic only.  Re-torque all nuts after 300 miles.  Adjust headlights after installation.
