Before beginning installation, read these instructions & enclosed driver’s WARNING NOTICE thoroughly & completely. Also affix WARNING decal in passenger compartment in clear view of all occupants. Please refer to Parts List to insure that all parts & hardware are received prior to disassembly of vehicle. If any parts are found to be missing, contact SKYJACKER® Customer Service at 318-388-0816 to obtain needed items. If you have any questions or reservations about installing this product, contact SKYJACKER® Technical Assistance at 318-388-0816.

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. Record this information below for future reference.

Important Notes

  • 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.
  • If Larger Tires (10% More Than the OEM Diameter) Are Installed, Speedometer Recalibration Will Be Necessary. Contact Your Local JEEP Dealer or an Authorized Skyjacker® Dealer for Details.
  • After Installation, a Qualified Alignment Facility Is Required to Align the Vehicle to the OEM Specifications.

Final Clearance Check & Torque Steps:

Notes: Check Front Center Axle Disconnect (CAD) connection & on RUBICON Models: Check Front & Rear locker connections.
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.

  1. Start vehicle. Make sure there are no dash lights pertaining to suspension.

  2. Jounce vehicle a couple of times. This will help suspension settle to new ride height. Cycle steering lock-to-lock & check all components for proper operation & clearances. Pay special attention to clearance between tires \ wheels, ADX Shocks & Reservoirs, control arms, brake hoses, ABS wiring, etc.

Rear Upper Cam Bolt Installation

Use Skyjacker # CAM500 Eccentric Cam Bolts for Rear Upper Control Arms at OEM axle mount brackets. Perform Steps on One Side at a Time.
Disconnect rear OEM upper control arm from OEM rear axle mount using a 15mm socket \ wrench.
Note: Only Disconnect One (1) Side at a Time.

The OEM control arm axle mount brackets have ‘knockout’ alignment inserts. Use inserts as a guide and cut a slotted rectangular hole. Using a Sawzall, Dremel or other small cutting device, cut out a notch on each side of rear upper OEM axle mount bracket. (See Photo # 14)

Connect OEM rear upper control arm to modified OEM rear axle mount using Skyjacker Eccentric Cam Bolt, Eccentric Washer & Nut using a 15mm & a 17mm socket \ wrench. (See Photo # 15)

With vehicle on ground & weight of vehicle on tires \ wheels, tighten front & rear eccentric cam bolts using a 15mm & a 17mm socket \ wrench. Note: These bolts can be rotated to adjust the axle pinion angle to eliminate any driveline vibration.

Final Notes

  • After installation is complete, double check that all nuts & bolts are tight. Refer to the following chart for proper torque specifications. (Note: Do not re-tighten nuts & bolts where thread lock compound was used.)
  • With vehicle placed on ground, cycle steering lock to lock & inspect steering, suspension, brake lines, front & rear drivelines, fuel lines & wiring harnesses for proper operation, tightness & adequate clearance.
  • Have headlights readjusted to proper settings.
  • Have a qualified alignment center align vehicle to OEM specifications.
  • After first 100 miles, check all hardware for proper torque & periodically thereafter.
