Front Installation

1. With the vehicle on flat level ground, set the emergency brake and chock the rear tires/wheels.
2. Raise the front of the vehicle and support the frame rails using jack stands at the indicated lift points mentioned in the OEM service manual.
3. Remove the front tires/wheels using a 22mm socket.
4. Disconnect the OEM lower skid plate by removing two rear bolts using a 12mm socket/wrench to access the sway bar frame mount.
5. Mark the front and back cam bolt positions on both OEM Lower Control Arm (LCA) frame mounts.
6. Loosen, but do not remove, the two cam bolts using two 22mm sockets/wrenches.
7. Disconnect the OEM sway bar from the frame mount by removing two OEM bolts per side using a 17mm socket/wrench.

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.
