TIP:
Establish the ¾” minimum gap required in Step 2B.
a.
For an air suspension system, place a ¾”
board on top of the tires after the air has
been let out of the airbags (Figure 2).
Place the fender on top of the board.
b.
For a spring suspension system, add ¾”
to the measurement from Step 2A.
STEP 3
A. Position the fenders exactly where they will be mounted.
a. Visually pick and mark the locations that
the brackets will attach to the frame.
B. It is possible to bolt a plate (not supplied)
to the frame and weld the brackets to that
plate (Figure 3). Another option is to weld
the bracket directly to the frame.
a. Plate should be a minimum
of ¼”
thick steel.
Tip: Check owner’s manual before
welding directly to the frame. Most
manufacturers do not suggest welding
anything directly to the frame.
NOTE:
Depending on the length of the truck frame and the placement of the mud flap hangers,
the fender may tuck inside the mud flap hanger. Figure 4 shows a truck with flaps and fenders.
Figure 3
NOTE: Do not drill into the weld or any other
part of the light box. If a mud flap is mounted to
the light box style fender and the mud flap is
backed over, it may cause the interior welded
plate to become loose. Slot the mud flaps to
prevent this issue. This is NOT covered under
warranty.
