PARTS LIST:

PROCEDURE:
REMOVE CONTENTS FROM BOX. VERIFY ALL PARTS ARE PRESENT. READ INSTRUCTIONS
CAREFULLY BEFORE STARTING INSTALLATION. ASSISTANCE IS RECOMMENDED TO
AVOID POSSIBLE INJURY OR DAMAGE TO THE VEHICLE. CUTTING IS REQUIRED.

1. Before beginning installation, measure the gap between the headlight assembly and the

bumper cover on both sides of the vehicle, (Figure 1). Also note the gap between the grille
shell and the bumper cover. Record these measurements as the installation requires removal
of the bumper bolts and you will need these measurements to properly readjust the bumper
height to its original position.

2. Starting at the front-driver side, remove the (2) factory bumper bolts, (Figure 1). WARNING!
Do not remove passenger and driver bumper bolts at the same time or the bumper may fall.
Only remove and install one Frame Mounting Bracket at a time. NOTE: Bumper bolts are held
in place by thin metal retaining clips. Discard the clips and remove the bolts.

3. Place the driver side Frame Mounting Bracket onto the vehicle and line it up with the (2)
mounting bolt holes, (Figure 2). Make sure there is a minimum of 1/8” clearance between the
top and bottom of the Mounting Bracket and the opening in the bumper. Secure the Mounting
Bracket to the vehicle using the factory bolts and double nut plate, (Figure 1). Check bumper
alignment and tighten these (2) bolts at this time. NOTE: It may be necessary to loosen and
readjust the bumper once the Grille Guard has been installed.

4. Repeat steps 2 & 3 for passenger side Frame Mounting Bracket installation.

5. Remove the license plate and bracket. Remove the plastic air dam from the bottom of the

bumper and place it on a clean, stable work surface. Note the location and type of all factory
hardware for reinstallation. NOTE: To release the 2-piece plastic clips, pry the center pin up
with a small flat blade screwdriver.

6. Next, from under the driver side of the bumper, remove the (2) factory hex nuts on the outside

of the frame channel, (Figure 3). NOTE: Do not allow the double bolt plate to fall into the
frame channel. Select the driver side Lower Mounting Bracket. Bolt the Mounting Bracket to
the factory double bolt plate and secure with the (2) factory hex nuts, (Figure 4). Do not tighten
hardware at this time. Repeat this step for passenger side Lower Mounting Bracket installation.

7. With assistance, position the Grille Guard up to the outside of the Frame Mounting Brackets
and Support Brackets. Attach the Grille Guard to the Frame Mounting Brackets using the
included (6) 12mm x 35mm Hex Bolts, (12) 12mm x 32mm OD Large Flat Washers, (6) 12mm
Lock Washers and (6) 12mm Hex Nuts, (Figure 5). Do not tighten hardware at this time.

8. Attach the Grille Guard to the Lower Mounting Brackets using the included (4) 12mm x 35mm
Hex Bolts, (8) 12mm x 24mm OD STD Flat Washers, (4) 12mm Lock Washers and (4) 12mm
Hex Nuts, (Figure 4). Do not tighten hardware at this time.

9. Hold the plastic air dam up in position and mark the location of the Lower Mounting Brackets
onto the top of the air dam, (Figure 6 - 9). Measure the location of the Mounting Brackets and
transfer these measurements onto the back of the air dam, (Figure 6 & 8). Place the air dam
back up to the (2) Lower Mounting Brackets to verify location. Check all measurements on the
vehicle. Once absolutely satisfied, use a hacksaw blade or utility knife to carefully cut (2)
openings in air dam, (Figure 10). Check fit, trim as necessary and reinstall air dam over Lower
Support Brackets with factory hardware. Do not cut through the top of bottom edge of the air
dam. NOTE: It may be necessary to loosen or remove the Lower Mounting Brackets to
reinstall the air dam. Reinstall the license plate and bracket.

10. Level and adjust Grille Guard and bumper, (if necessary), and tighten all hardware at this time.

11. Do periodic inspections to the installation to make sure that all hardware is secure and tight.

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.
For stainless steel: Aluminum polish may be used to polish small scratches and scuffs on the finish. Mild
soap may be used also to clean the Grille Guard.

For gloss black finishes: Mild soap may be used to clean the Grille Guard.
