2. Start installation from under the front of the vehicle. Determine if the vehicle is equipped with tow hooks.
Tow Hook equipped vehicles:
a. Remove the factory tow hook from the end of each frame channel, (Figure 1). NOTE: The driver
side tow hook removal and the reinstallation of both tow hooks with the Grille Guard is difficult and
assistance is highly recommended.
i. Option 1: Remove the hex bolts securing the driver side of the bumper to the bracket. Use
a short pry bar or large screwdriver to move the tab on the bumper bracket up and away
only enough to clear the hex bolt and slide it out past the bumper bracket, (Figures 2A, 2B
& 5).
ii. Option 2: Remove plastic radiator grille. Loosen and/or completely remove the front
bumper to remove the long hex bolts through the tow hooks, (Figure 2B).
b. Reattach the bumper after the tow hooks have been removed, (Figure 5). Leave factory hardware
loose at this time.
c. Next, select (1) Frame Bracket and the driver side Mounting Bracket, (Figure 9). Bolt the Mounting
Bracket to the bottom of the Frame Bracket with (3) 8mm x 25mm Hex Bolts, (3) 8mm Lock
Washers and (3) 8mm Flat Washers, (Figure 10). Do not fully tighten hardware at this time.
d. Insert the Bracket assembly through the opening in the plastic bumper, (Figure 5). Line up the (3)
holes in the Frame Bracket with the holes in the end of the frame channel.
e. Insert the driver side tow hook back into position in the end of the frame above the Bracket
Assembly, (Figure 10). Reattach the tow hook using only the long factory hex bolt inserted through
the Frame Bracket and tow hook at this time. Loosen and reattach bumper as required to reinstall
the long bolt. If tow hooks are not going to be reinstalled, skip ahead to Step d, "Vehicles without
tow hooks" installation instructions.
f. Leave hardware loose at this time.
g. Repeat Steps c - f to install the passenger side Bracket assembly and tow hook. Once both
Bracket assemblies have been installed, skip forward to Step 3.
Vehicles without tow hooks:
a. Cut out the lower portion of the indented area in both sides of the plastic bumper insert to clear the
Brackets as pictured, (Figures 3 & 4). IMPORTANT: Make several small cuts for best fit. NOTE:
The plastic panel is held in place with several small screws. The screws at the top corners are
difficult to impossible to reach and remove with the bumper in place without damaging the cover. If
you prefer to remove the panel to cut out the openings, it may be necessary or easier to remove
the plastic grille then the steel bumper assembly with the plastic panel attached to access all of the
small screws and clips.
b. Reattach the bumper and/or bumper insert and grille, (if removed), once openings have been cut
out and checked for clearance, (Figure 4). Tighten all factory bumper hardware only at this time.
c. Select (1) Frame Bracket, (Figure 6). Insert the Bracket through the opening in the plastic bumper,
(Figures 4 & 5). Line up the (3) holes in the Bracket with the holes in the end of the frame channel.
d. Select (1) 12mm Double Bolt Plate, (Figure 7A). Insert the Bolt Plate into the end of the frame
channel, through the (2) holes in the side of the frame and out through the Bracket. Secure the
Double Bolt Plate to the Bracket with (2) 12mm Flat Washers, (2) 12mm Lock Washers and (2)
12mm Hex Nuts, (Figure 7B). Snug but do not fully tighten hardware at this time. Repeat this Step
to install the 12mm x 35mm Single Bolt Plate, (Figure 8A), into the remaining hole in the other side
of the frame channel and Bracket, (Figures 8B & 8C).
e. Next, select the driver side Grille Guard Mounting Bracket. Bolt the Mounting Bracket to the bottom
of the Frame Bracket with (3) 8mm x 30mm Hex Bolts, (3) 8mm Lock Washers and (3) 8mm Flat
Washers, (Figures 9 & 10). Do not tighten hardware at this time.
f. Repeat Steps c - e to install the passenger side Frame and Mounting Brackets.
3. 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 Hex Bolts, (8) 10mm Flat Washers, (4) 10mm Lock
Washers and (4) 10mm Hex Nuts, (Figure 10). Snug but do not tighten hardware at this time.
4. Check the Grille guard side to side alignment with the vehicle. Adjust as required then tighten only the (6)
8mm Hex Bolts securing the Mounting Brackets to the bottom of the Frame Brackets.

a. Vehicles with tow hooks: Once adjusted side to side and after the 8mm hardware is tightened,
insert the short factory tow hook bolt, (one per tow hook), through the remaining hole in the Frame
Bracket and back into the tow hook. Repeat to reinstall the passenger side tow hook bolt.
5. Through the radiator opening, 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, (Figures 11B, 13 & 14). Select the
driver side Inner Top Bracket and (1) Backing Plate, (Figure 11A). Hold the Inner Bracket up to the bottom
of the brace tube with the Backing Plate over the top. Bolt the Brackets together around the square tube
with (2) 6mm x 25mm Hex Bolts, (2) 6mm Lock Washers and (2) 6mm Flat Washers, (Figure 11B). Leave
loose at this time. Repeat this Step to install the passenger side Inner Bracket and Backing Plate.
6. Reinstall the plastic grille if previously removed.
7. Select the driver side Outer Top Bracket, (Figure 12). Insert the Outer Bracket through the grille and up to
the Inner Top Bracket assembly, (Figure 13). Slide the Bracket assembly up or down the tube to match up
the Outer Top Bracket to the hole in the Grille Guard upright. Bolt the Outer Bracket to the top of the Inner
Bracket with (2) 6mm x 25mm Hex Bolts, (2) 6mm Lock Washers and (2) 6mm Flat Washers, (Figure 15).
Leave hardware loose at this time.
8. Line up the outer bent end of the Top Bracket with the hole in the Grille Guard upright. Bolt the bent end of
the Outer Top Bracket to the upright with (1) 10mm x 25mm Button Head Allen Bolt, (2) 10mm Flat
Washers and (1) 10mm Nylon Lock Nut, (Figures 15 & 16).
9. Repeat Steps 7 – 8 for passenger side Top Bracket assembly installation, (Figure 14).
10. Level and adjust the Grille Guard and fully tighten all hardware including bumper, bumper bracket, tow
hook if equipped and all Grille Guard Bracket hardware. IMPORTANT: Adjust the position of the Top
Brackets so that they cannot come in contact with the plastic grille, (Figures 13 - 15).
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.
