4. Repeat Steps 1—3 to install the (2) remaining driver side Brackets.
5. Select the driver/left sidebar. Carefully position the Driver Sidebar onto the (3) Mounting Brackets.
IMPORTANT: Do not slide, (front to back or rotate), the Sidebar on the Brackets or damage to the
finish on the Sidebar may result. Attach the Sidebar to the Mounting Brackets with (6) 8mm x 25mm
Hex Bolts, (6) 8mm Lock Washers and (6) 8mm Flat Washers, (Figure 8). Do not tighten hardware.
6. Level and adjust the Sidebar and tighten all hardware.
7. Move to the passenger side of the vehicle. On the passenger side, determine if the vehicle is equipped
with a plastic diesel exhaust fluid (DEF) tank, (Figures 9 & 10).
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 limited. 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 tank, remove the (3) hex bolts attaching the tray to the
frame, (Figure 9), and remove the tray. 2017 2500/3500 models: Remove the (4) hex bolts
attaching the plastic cover to DEF tank, (Figure 10A) and remove plastic cover, (Figure 10B).
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 11). 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.
8. Locate the first tab on the edge of the pinch weld, (Figures 2—4, 13 & 15). Select the Upper Bracket,
(Figure 12). Repeat Steps 2 & 3 to attach the passenger front Upper Bracket to the side of the body
panel, (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, (Figure 13). Attach the Lower
Bracket to the bottom of the body and weld-nut with (1) 8mm x 25mm Hex Bolt, (1) 8mm Lock
Washer and (1) 8mm Flat Washer, (Figures 16 & 20). Leave loose at this time.
b. Models with flat tab and hole: Insert the 8mm Bolt Plate down through the hole in the Upper
Bracket and mounting tab, (Figures 14 & 15). 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 & 20).
Leave loose at this time.
10. Line up the side tab on the Lower Bracket with the threaded hole in the side of the Upper Bracket.
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 20). Leave loose at this time.
11. Repeat Steps 1—3 for the (2) remaining passenger side Bracket installations. NOTE: Cradles on
Brackets installed on passenger side will face forward.
a. 2017 2500/3500 DEF tank models: Locate the 2nd tab bracket location along the bottom edge
of the body, (pinch weld), (Figure 17). Hold the DEF cover in place and mark the 2nd Bracket
location onto the cover, (Figure 18). Use a sharp knife or hacksaw blade to carefully cut a slot
in the plastic cover to clear the 2nd Bracket, (Figure 19). Remove as little plastic as possible.
12. Repeat Steps 5 & 6 to install the passenger Sidebar, (Figure 21).
13. Once the Sidebars are fully installed and all hardware fully tightened, reinstall the DEF tank and cover,
if equipped, as described in Step 7 & 11.
14. 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.
