Parts Included: License Plate mounting bracket Assembly. Includes Base Plate and
License Plate Holder.
License Plate mounting Screws: (4) 6mm X 12mm (Phillips head) and
6mm nuts (10mm wrench size)
Base plate mounting bolts/screws: (4) 6mm X 20mm bolts with washer
nuts.
Tools Needed: T30 Torx (Optional), 10mm socket with ratchet Note: 1/4-inch drive
preferred but 3/8 will work but extra caution will be needed when tightening screws.
Phillips Screwdriver and 10 wrench
1/4 inch drill bit and drill.
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: Center base plate bracket as show in figure 1. NOTE: On some vehicle the rubber air
dam will have to be slightly folded back to allow rods to enter tubes. This ensures maximum
ground clearance. The bracket will be centered with back of the bracket up against the lip of
the plastic under pan as shown in figure 2. Note: Double sided tape (Included) can be used to
help hold bracket in place while aligning. Slide the front bracket into the tubes to verify
alignment. Back of front plate should be approximately ¼” from the front bumper. Remove
when alignment is complete and continue to step 4.
Step 4: Once base plate is correctly positioned and while holding the plate in place, carefully
drill two 1/4” holes for the rear mounting bolts. See figure 3.
Step 5: Using the 6mm bolts and washer nuts secure the rear of base plate to the vehicle.
Access to the top of the bolts is through the square openings as shown in figure 4.
Step 6: Verify alignment with front license plate bracket in place. If alignment is correct the
front plate should be centered left to right and be approximately 1/4" from bumper, remove

front license plate bracket and drill two 1/4” holes for front screws. NOTE: Using the T30 Torx
socket you may remove the (4) screws holding the rear of the under panel on to gain easier
access to the top of the front bolts. See figure 4a. Requires elevating the front of he vehicle or
use of a lift. However, you can access the top of the front bolts through the square openings.
Using (2) 6mm X 20mm bolts and washer nuts secure the front of the base plate.
Step 7: 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 8: 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 5. In 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 6) 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.
