REMOVE CONTENTS FROM BOX. VERIFY ALL PARTS ARE PRESENT. READ INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION. ASSISTANCE IS RECOMMENDED.
-
Start the installation under the driver side of the vehicle. Locate the 6 plugs along the bottom edge of the body. Mounting Brackets will bolt to the 1st, 3rd, 4th and 6th threaded mounting holes, ( Figures 1— 6). Remove the plastic plugs from each mounting location. Directly above each threaded insert is a top mounting location on the side of the body panel. Hold a Bracket up in place to help determine the mounting holes to use along the body.

To protect your investment, wax this product after installing. Regular waxing is recommended to add a protective layer over the finish. Do not use any type of polish or wax that may contain abrasives that could damage the finish. Aluminum polish may be used to polish small scratches and scuffs on the finish. Mild soap may be used also to clean Sidebars.
