PROCEDURE:

REMOVE CONTENTS FROM BOX AND VERIFY ALL PARTS ARE PRESENT. READ IN STRUCTIONS
CAREFULLY. DO NOT ATTEMPT INSTALLATION ALONE; PERSONAL INJURY OR DAMAGE TO THE
VEHICLE MAY RESULT. CUTTING MAY BE REQUIRED. ASSISTANCE IS HIGHLY RECOMMENDED.
GRILLE GUARD INSTALLATION MAY INTERFERE WITH FRONT MOUNTED SENSORS.

1. Start installation at the front, passenger side of the vehicle. Determine if the vehicle is equipped with tow
hooks, (Figure 1).
Tow Hook equipped vehicles:

Remove the factory tow hooks from the end of each frame channel, (Figure 2). NOTE: Tow hooks
cannot be reinstalled with the Grille Guard.

Vehicles without tow hooks:

Cut out the indented area in both sides of the plastic bumper to clear the Brackets only. IMPORTANT:
Make several small cuts for best fit around the Frame Mounting Bracket.

2. Next, select the passenger side Frame Bracket, (Figure 3). From behind the bumper, insert the Bracket
up and out through the opening in the plastic bumper, (Figures 4A & 4B). Line up the (2) holes in the
Bracket with the holes in the frame for the tow hook.

3. Select (2) 12mm Bolt Plates, (Figure 5). Insert the Bolt Plates into the end of the frame channel and out
through the holes in the bottom and outer side of the frame, (Figures 6A & 6B). Secure the Bracket to the
Bolt Plates with (2) 12mm Flat Washers and (2) 12mm Nylon Lock Nuts, (Figure 6B). Do not fully tighten
hardware at this time.

4. Select the passenger side Mounting Bracket, (Figure 7). Bolt the Mounting Bracket to the bottom of the
Frame Bracket with (2) 10mm x 30mm Button Head Bolts, (4) 10mm Flat Washers and (2) 10mm Nylon
Lock Nuts, (Figure 8). Do not tighten hardware at this time.

5. Repeat Steps 2—4 to install the driver side Frame and Mounting Brackets.

6. Next, open the hood and remove the plastic cover between the top of the grille and radiator, (Figure 9).
NOTE: Use a small flat head screw driver to pop up the center of the plastic clips. Remove the hardware
securing the outer ends of the grille to the vehicle.

7. Carefully pull the grille forward to release it from the clips. Tilt the top of the grill forward to access the area
between the grille and the radiator, (Figure 10). Do not remove grille.

8. Locate the square tube support braces running up at an angle from the top of the frame channel to the

bottom of the hood release mechanism, (Figure 10). Select the passenger side Inner Top Bracket and (1)
“U” Backing Plate, (Figure 11). Hold the “U” Bracket up to and around the back of the square tube,
(Figure 12). Bolt the Inner Top Bracket to the “U” Bracket with (2) 6mm x 25mm Hex Bolts, (2) 6mm Lock
Washers and (2) 6mm Flat Washers, (Figure 13). Leave loose at this time.

9. Repeat Step 8 for the driver side Inner Top Bracket installation.

10. With assistance, hold the Grille Guard up in position on the outside of the Mounting Brackets. Bolt the

Grille Guard to the Brackets with (4) 10mm x 30mm Button Head Bolts, (8) 10mm Flat Washers and (4)
10mm Nylon Lock Nuts, (Figure 14). Do not fully tighten hardware at this time.

11. Select the passenger side Outer Top Bracket, (Figures 11 & 16A). Line up the bent end of the Outer
Bracket with the hole in the Grille Guard upright.

12. Insert the Outer Top Bracket through the grille and up to the Inner Top Bracket assembly, (Figures 15 &
16A). Bolt the Outer Bracket to the top of the Inner Bracket with (2) 8mm x 25mm Hex Bolts, (4) 8mm Flat

Washers and (2) 8mm Nylon Lock Nuts. NOTE: Slide the Inner Bracket assembly up or down the square
tube to match up with the Outer Top Bracket and grille opening. Leave hardware loose at this time.

13. Line up the outer bent end of the Top Bracket with the hole in the Grille Guard upright, (Figure 16A).
Outer Top Bracket Installation on Denali models: Due to the smaller openings in the Denali grille, it

may be necessary to swap the passenger side Top Outer Bracket with the driver side to line up properly
with the openings in the grille, (Figures 16A & 16B).

14. Bolt the Top Bracket to the upright with (1) 8mm x 25mm Button Head Allen Bolt, (2) 8mm Flat Washers
and (1) 8mm Nylon Lock Nut, (Figures 16A & 16B). Do not tighten hardware at this time.

15.

Repeat Steps 11—14 for driver side outer Top Bracket installation.

16. Level and adjust the Grille Guard and fully tighten all hardware. IMPORTANT: Adjust the position of the

Top Brackets up or down the square tube as required so that they cannot come in contact with the plastic
grille, (Figure 15). Swap passenger side with driver side if necessary to clear the plastic grille as
described in Step 13.

17. Push the grille back into position and into the factory clips and secure with the factory hardware. Reinstall
the top plastic cover using the factory hardware, (Figure 9).

18. 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.
