How to Install SkyJacker 6-7 in. Long Arm Suspension Lift Kit w/ Shocks (07-17 Wrangler JK) on your Jeep Wrangler

1. Park the vehicle on flat level ground, set the emergency     brake, & block the rear tires / wheels.

2. Raise the front of the vehicle & support the frame rails using jack stands. 

3. Disconnect the OEM front sway bar end links using a 18mm     socket & disconnect the OEM front track bar from the axle using a 21mm socket. (See Photo # 1)

4. If installing a Skyjacker steering stabilizer (Part # 7003), remove the OEM steering stabilizer using a 18mm socket. (See Photo # 2)

5. Disconnect the OEM front shocks using a 18mm socket. Remove the front tires / wheels & remove the OEM front coil springs. (See Photo # 3) Remove the OEM front shocks.

6. Locate the OEM lower control arm mount on the frame.     Note: It will be necessary to modify these mounts to allow for     the installation of the new Skyjacker lower control arm     brackets. Remove the OEM automatic transmission skid plate & remove the OEM lower control arms, one side at a time.

7. Using a grinder, remove the weld attaching the inner mounting plate to the     frame. All that will be left is the single mounting plate under the frame. (See the Arrow in Photo # 4)

8. Using a transmission jack, support the rear of the transfer case.         Disconnect the transmission from the OEM cross member. Raise       the transmission / transfer case approximately 2". This will allow       easier access around the exhaust to install the new Skyjacker front       control arm brackets.

FINAL 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.

• After the installation is complete, double check that all nuts & bolts   are tight. Refer to the following chart for the proper torque   specifications. (Do not retighten the nuts & bolts where thread lock  compound was used.)

• With the vehicle placed on the ground, cycle the steering lock to lock   & inspect the steering, suspension, brake lines, front & rear   drivelines, fuel lines, & wiring harnesses for proper operation,   tightness, & adequate clearance.

• Have the headlights readjusted to the proper settings.

• Have a qualified alignment center align the vehicle to the OEM specifications.

• After the first 100 miles, check all hardware for the proper torque & periodically thereafter.
