License Plate mounting Screws: (4) 6mm X 12mm (Phillips head) and

Base plate mounting screws: (2) 4.2mm X 35mm screws and (2) 7/16”
nylon spacers
Tools Needed: 7mm, 8mm & 10mm socket with ratchet Note: 1/4-inch drive referred
but 3/8 will work but extra caution will be needed when tightening bolts.
Phillips screwdriver, and 10mm wrench
Step 1: Ensure all parts listed above are accounted for. Note: If at any time during the
installation process you need assistance please call [phone].
Step 2: Separate the license plate holder from the base by simply pulling the pull pin ring
outward and sliding apart.
Step 3: Remove the two center screws as shown in figure 1. Position the base mount with the
pull pin on the right side as you are looking at the vehicle and line up to two holes where the
two factory screws were just removed. See figure 2.
Step 4: Using the two 4.2mm X 35mm and the two 7/16” spacers, screws secure the base plate
to the vehicle. See figure 3.
Step 5: Secure the license plate and frame (optional) to the license plate bracket using the
screws and nuts provided. Requires the Phillips screwdriver and 10mm wrench (Not included).
Step 6: NOTE: Slide the license plate rods into the two tubes located on the base plate. Slide the
rods into the tubes until the rods hit the pull pin. Simply pull the ring on the pull pin and
advance the rods. Release ring and continue to advance rods until the pull pin locks into place.
NOTE: The rods and spring-loaded pull pin are required to be sprayed periodically with WD-40
or any other silicone type spray lube. Failure to do so could result in either the failure of the
pull pin or the rods becoming difficult to remove or reinsert. Note: In harsh environments,
such as areas where roads are either salted or sanded in the winter, spraying of the rods and

pull pin should be performed on a regular basis. Failure to provide this maintenance may void
your warranty. See figure 4. On some occasions the license plate may require a little
adjustment to level. Simply pull pin and slide plate out approximately two inches, grab frame at
arrows (See figure 5) and rotate. If plate is high on left or right side, rotate high side down
slightly and release. Verify alignment and repeat as necessary. Once leveled plate will remain
level.
