INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION. ON MODELS WITH DEF TANK,
SELECT A FLAT, LEVEL AREA FOR INSTALLATION. MAY REQUIRE CUTTING.
1. Start the installation under the Driver/Left side of the vehicle. Locate the 4 tabs along the bottom edge
of the body, (pinch weld). Mounting will use the 1st, 2nd and 4th tab locations, (Figure 1). Directly
above each tab is a top mounting location on the side of the body panel. Hold a Bracket up in place to
help determine the mounting holes to use along the body.
2. Determine the correct procedure for your model year and each Bracket location.
Bottom mounting location on the edge of the pinch weld.
Flat tab on pinch weld with factory installed weld nut:
Thread hex bolt into weld nut from the backside-down to clear paint from threads, (Figure 2).
Flat tab on pinch weld with hole:
Select (1) 8mm Clip Nut. Slide the Clip Nut over the tab with the nut facing up behind the tab,
(Figure 3). Line up threaded nut with hole in the tab.
Locate top mounting location on the back side of the rocker panel.
Models with factory installed threaded insert in rocker panel:
Thread 8mm Hex Bolt into threaded insert to clear paint as required.

Remove the rubber plug from the larger hole. Select (1) 8mm Clip Nut. Slide the Clip Nut into
the larger hole. Line up the threaded nut with the smaller hole, (Figure 3).
3. Select (1) Driver/Passenger Mounting Bracket. Bolt the Mounting Bracket to the Clip Nuts and/or the
factory threaded holes with (2) 8mm Hex Bolts, (2) 8mm Lock Washers and (2) 8mm Flat Washers,
(Figure 4). Do not tighten hardware.
4. Repeat Steps 1—3 to attach the remaining (2) Driver/Left Mounting Brackets, (Figures 5 & 6).
5. Select the Driver/Left RS2 Running Board. Attach the Running Board to the rear faces of the (3)
Mounting Brackets with (6) 10mm Hex Bolts, (12) 10mm Flat Washers and (6) 10mm Nylon Lock Nuts,
(Figure 7). Do not tighten hardware.
6. Level and adjust the Running Board and fully tighten all hardware.
7. Move to the Passenger/Right side of the vehicle. On the Passenger/Right side, determine if the vehicle
is equipped with a plastic diesel exhaust fluid (DEF) tank, (Figures 8 & 9).
Models without DEF tank, skip to Step 8.
Models with DEF tank: The tank sits close to the side of the body. With specialized tools, the
passenger front upper and lower Bracket can be installed but room is very limited.
Determine model year of vehicle before proceeding.
Up to 2016 models:
It may be easier to drop the tank down to access the inner side of the body panel for upper bracket
installation. Tank will not need to be removed, only dropped down for access to mounting location.
IMPORTANT: If tank is full, it will be very heavy and assistance is highly recommended to avoid injury
or damage to the vehicle or the tank. It is recommended that installation is performed when the DEF
tank is low on fluid before dropping the tank.
a. On models with plastic lower tray under the tank, remove the (3) hex bolts attaching the tray to
the frame, (Figure 8), and remove the tray.
b. Release the tank filler hose. Release the plug for the sending unit on the top of the tank.
c. Support the tank with a floor jack. Place a smooth flat surface, (wooden block for example),
between the floor jack and the tank to avoid damaging the plastic tank. Do not push up on the
tank; only support the weight of the tank with the jack.
d. Remove the (2) bolts securing the tank straps to the vehicle, (Figure 9). Tilt the straps to
release from the brackets. Slowly lower the tank until the top of the tank is almost visible. Use
blocks or stands to support the tank while installing the front Upper and Lower Brackets.
e. Proceed to Step 8.
2017 models and on:
a. Remove the (4) hex bolts attaching plastic cover to DEF tank, (Figure 10A) and remove plastic
cover, (Figure 10B).NOTE: On 2017-on 2500/3500 models, only remove plastic cover from
DEF tank. Do not lower DEF tank and proceed to Step 8.
8. Locate the first tab on the edge of the pinch weld, (Figure 11). Select the Upper Bracket, (Figure 12).
Attach the Upper Bracket with (1) 8mm x 25mm Hex Bolt, (1) 8mm Lock Washer and (1) 8mm Flat
Washer, (Figure 13). Do not tighten hardware at this time.
9. Line up the hole in the bottom of the Upper Bracket with the hole in the tab on the pinch weld.
a. Models with a weld-nut: Slide the Bracket over the weld-nut. Attach the Lower Bracket to the
bottom of the body and weld-nut with (1) 8mm x 40mm Hex Bolt, (1) 8mm x 24mm Flat Washer,
(1) 8mm x 28mm Flat Washer and (1) 8mm Nylon Lock Nut, (Figures 14 & 15). Do not tighten
hardware.
b. Models with flat tab and hole: Insert the 8mm Bolt Plate down through the hole in the Upper
Bracket and tab. Attach the Lower Bracket to the bottom of the body and Bolt Plate with (1)
8mm Flat Washer and (1) 8mm Nylon Lock Nut, (Figures 16). Do not tighten hardware.
10. Attach the Lower Bracket to the Upper Bracket with (1) 8mm x 25mm Hex Bolt, (1) 8mm Lock Washer
and (1) 8mm Flat Washer, (Figure 17). Do not tighten hardware.
11. Repeat Steps 1—4 to attach the (2) remaining Passenger/Right Mounting Brackets.

a. 2017-on DEF tank models: Locate the 2nd tab bracket location along the bottom edge of the
body, (pinch weld), (Figure 11). Hold the DEF cover in place and mark the location onto the
cover, (Figures 18A & 18B). Use a sharp knife or hacksaw blade to carefully cut a slot in the
plastic cover to clear the 2nd Bracket. Remove as little plastic as possible.
12. Repeat Step 5to attach the Passenger/Right Running Board.
13. Once the Running Board has been installed and all hardware fully tightened, reinstall the DEF tank and
cover, if equipped, as described in Step 7.
14. (OPTIONAL) If treads on the stepping platform are desired, remove the platforms from both Running
Boards and reattach them to the opposite sides, (Figure 19).
15. Do periodic inspections to the installation to make sure that all hardware is secure and tight.
To protect your investment, Do not use any type of polish or wax that may contain abrasives that could damage the
finish. Mild soap may be used also to clean the Running Boards.
