License Plate Mounting Screws: (4) 6mm X 12mm (Phillips head) and
6mm (10mm wrench size)
Base plate mounting screws: (1) 4.8mm X 25mm, (1) 3/16” nylon spacer,
3M tape and alcohol pad
Tools Needed: 8mm & 10mm sockets with ratchet Note: 1/4-inch drive preferred but

Phillips Screwdriver
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 factory screw using the 8mm socket just right of center (as looking at the
vehicle) as shown in figure 1.
Step 4: Now position the base mount with the hole towards the back of the car, centered over
the hole where the factory screw was just removed. Tubes will be facing down. Use alcohol
pad to clean area where 3M tape will make contact. Note: The spacer will sit inside the opening
where the factory screw was removed. If not properly inserted, the base plate will not sit flush.
See figure 2. Ensure the base plate is properly aligned prior to sticking the 3m tape to the
contact point. See figure 2a. Using the 4.8mm X 25mm screw, and the 3/16” nylon spacer,

loosely secure the base plate in place. (Note: The screw will go through the base plate, then the
spacer. See figure 3.
Step 5: Slide the front plate into the base plate and verify alignment. The front plate should be
square to the bumper. Once verified, securely tighten the base plate mounting screw.
Step 6: Secure the license plate and frame (optional) to the license plate bracket using the
screws provided. Requires the Phillips screwdriver and 10mm wrench (Not included).
Step 7: 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 grab frame at arrows (See figure 5) and rotate. If the plate is high on left or right
side, rotate high side down slightly and release. Repeat as necessary. Once leveled plate will
remain level.
