Step 1 - Driver-Side
As shown, mark the pinch weld for the front
hole of each bracket. The holes will be 7" back
from the wheel well for the front bracket and
34-3/8” back for the rear bracket.
Step 4 - Driver-Side
Place the second bracket up to the inside of the
pinch weld, lined up with the second marked
hole, and secure it using a clamp. Note: Some
under coating will need to be scraped off so the
bracket will sit flat with the pinch weld.
Using the bracket holes as a reference, mark
the center of the two holes on the pinch weld
and the two holes on the angled surface that
match up closest to the body plug.
Step 2 - Driver-Side
Attach the front driver side bracket by lining up the bracket
with the first marked spot, then mark the second pinch weld hole.
Make sure to leave enough space at the top of the pinch weld for
the retainer and hardware to sit flat against the outside pinch weld.
Step 3 - Driver-Side
After the holes are marked, drill an
11/32" hole at each marked location.
Fasten the bracket to the pinch weld using
the provided 5/16"-18 hardware and retainer
plate. The top hole will be drilled later in the
installation.

Step 5 - Driver-Side
Once the four holes have been marked, drill
the two pinch welds and the marked hole,
toward the rear of the vehicle on the angled
surface, with an 11/32" bit.
Drill the last hole toward the front of the vehicle
on the angled surface with a 3/16" drill bit.
Step 8 - Driver-Side & Passenger-Side
Remove the body plug next to the 11/32” hole
and install a U-nut. Reinstall the bracket and
use a 1/4” bolt and washer in the U-nut. If the
optional hole was drilled, use a 5/16” x 3/4”
self-tapping screw. Tighten all hardware to the
recommended torque specifications on page 1.
Repeat steps 1 - 8 to install the
front two passenger-side brackets.
Step 6 - Driver-Side
Remove the body plug on the angled surface,
toward the rear of the vehicle, that the 11/32"
hole should have been drilled next to. Slide
the U-nut in place over the 11/32" hole.
Place the bracket into position and fasten it to
the pinch weld using the provided 5/16" bolts,
washers, nuts and retainer plate. Do not fully
tighten at this time.
Insert a 1/4” bolt and flat washer into the U-nut
bracket hole and the 5/16” x 3/4” self-tapping
screw through the 3/16” hole. Tighten all
hardware securing the second bracket.
Step 7 - Driver-Side
Drill the top hole of the front bracket by placing
a straight edge or level on the flat surface of
the second bracket, and adjusting the front
bracket until the straight edge is sitting level
with the vehicle. Mark the center of the top
slotted hole.
Remove the bracket and drill an 11/32” hole
where marked. Optional: Before removing the
bracket, the center of the extra hole can be
marked and drilled with a 3/16” bit.

Step 11 - Passenger-Side
Reattach the brackets to the pinch weld and
use a 5/16” x 3/4” self-tapping screw for
each upper hole. Tighten all hardware to the
recommended torque specifications on page 1.
Note: To complete the installation,
refer to the manual included with
your running boards / side steps.
Step 10 - Passenger-Side
Using the running board or a level, align each
of the three rear brackets with the first two
brackets and mark one of the three top holes.
Additional holes can be marked, but are
optional. Remove the brackets and drill
each marked hole with a 3/16” drill bit.
Step 9 - Passenger-Side
Measure from the front wheel well and mark
the front hole for the three rear brackets:
First hole: 48-7/8”
Second hole: 66-7/8”
Third hole: 95-7/8”
Place a bracket at each location and mark
the second pinch weld hole. Drill all marked
locations with a 11/32” bit. After the holes
are drilled attach the brackets to the pinch
weld with the provided 5/16” bolts, washers,
nuts and retainer plates.
