MOUNTING BRACKET KIT
INSTALLATION INSTRUCTIONS
his is one of our EZ2 series brackets, which
allows the visible front portion of the bracket
to be easily removed from the front of the
vehicle (Fig.A and Fig.B). The bracket consists of
a main receiver brace, two removable front brac-
es, two center braces and a hardware pack.
The main receiver brace mounts to the frame
rails and the bumper core. The removable front
braces install in the main receiver brace.
Before starting the installation, lay out the kit
components in order, as they will be used. This
will give you a visual idea of how the components
work, and will also confirm that everything is pres-
ent and accounted for.
IMPORTANT: All brackets must be assembled with all the bolts left loose for final adjustment and positioning (before
tightening) unless otherwise instructed. All bolts must be torqued for proper strength. If more than one bolt is used per
fastening point, the diagram may only show one.
• Use flat washers over all slotted holes • Use lock washers on all fasteners
• Installation of most mounting brackets requires moderate mechani-
cal aptitude and skills. We strongly recommend professional installa-
tion by an experienced installer.
• The installer must read the instructions and use all bolts and parts
supplied. Failure to securely fasten the bracket could result in loss of
the towed vehicle.
• Do not use this document for custom fabrication, as it may not show
all parts or structural components. Custom fabrication or an attempt to
copy this bracket design could result in loss of the towed vehicle.
• The owner must inspect all mounts and brackets before each use
for cracks or other signs of fatigue. Also, inspect the fasteners for
proper torque, according to the bolt torque requirements chart on the
last page. Failure to do so could result in loss of the towed vehicle.
• The owner must check the vehicle manufacturer's instructions for
the proper procedure(s) to prepare the vehicle for towing. Some
vehicles must be equipped with a transmission lube pump, an axle dis-
connect, driveline disconnect or free-wheeling hubs before they can be
towed. Failure to properly equip the vehicle will cause severe damage
to the transmission.
• If running changes were made by the vehicle manufacturer after this
bracket was designed, some bolts or other fasteners in the hardware
pack may no longer be the correct size. It is the installer’s responsi-
bility to verify that the bracket is securely fastened to the vehicle and
fitted with the correct hardware to account for these changes. Failure to
securely fasten the bracket could result in loss of the towed vehicle.
ROADMASTER Limited Warranty, including One-Year Conditional Warranty Text and Product Registration Card, in Carton.
• If the towed vehicle has been in an accident, it must be properly re-
paired before attaching the bracket. Do not install the bracket if any
structural frame damage is found. Failure to repair the damage could
result in the loss of the towed vehicle.
• Some motorhome chassis have such a tight turning radius that you can
damage your motorhome, towed vehicle, tow bar or bracket while turning
sharply. Before getting on the road, test your turning radius in an
empty parking lot. Turning too sharply could result in non-warranty
damage to towing system, motorhome and/or towed vehicle.
• Do not back up with the towed vehicle attached or non-warranty
damage will occur to your towing system, motorhome and/or towed
vehicle.
• The safety cables must connect the towing vehicle to the towed
vehicle frame to frame, with the cables crossed, with enough slack
for sharp turns. Refer to the cable instructions for proper routing.
Failure to leave enough slack in the safety cables, or failure to connect
the safety cables frame to frame, will result in the loss of the towed
vehicle.
• This bracket is designed for use with ROADMASTER tow bars and
ROADMASTER adaptors only. Using this bracket with other brands,
without an approved ROADMASTER adaptor, may result in non-
warranty damage or injury.
• Upon final installation, the installer must inspect the bracket to en-
sure adequate clearance, particularly around hoses, air conditioner
lines, radiators, etc., or non-warranty damage to the towed vehicle
will result.
• This bracket is only warranteed for the original installation. Installing
a used bracket on another vehicle is not recommended and will void
the warranty.
Failure to follow these instructions
can result in property damage,
personal injury or even death.

17. Remove the two air bag sensors from the center of the bumper core by removing two T25 Torx bolts (Fig.S). Note: do
not unplug the air bag sensors — if the ignition is turned on while the sensors are unplugged, the air bag sensor light will
be triggered and will need to be reset by the dealer.
18. On each side, using a 12 point, 10mm socket, remove three bolts attaching the bumper core to the end of the frame
rail (Fig.T). Note: only two are shown in Figure T. The third is below the bumper core support.
19. Place the bumper core upside down on a workbench
area. Place the main receiver brace over the top of the
bumper core supports. Slide it forward until the main
receiver brace contacts the rear of the bumper core
(Fig.U). Note: when the main receiver brace is clamped to
the bumper core, only the lower end of the side mounting
points should be touching the rear of the bumper core.
There should be approximately a ½" gap at the top (Fig.V).
Clamp the main receiver brace to the bumper core
supports and clamp both to a workbench. Using a ½" drill
bit, and the pre-existing holes in the main receiver brace
as templates, drill through both sides of the bumper core
on each side (Fig.W — next page).

23. On each side, remove the rubber plug in the side of the frame rail (Fig.BB).
24. Position the rear mounting plate against the side of the frame rail so the two upper mounting points fall through the
opening in the front of the core support. Place a ½" lock washer over a ½" x 1½" bolt, and place a ¼" x 1" x 2" backing
plate with wire through the opening in the front of the frame rail. Thread the ½" x 1½" bolt into the backing plate (Fig.CC).
25. Trim the air deflector on each side using the red lines
in Figure DD as a guide.
26. Place the bumper core and main receiver brace over
the ends of the frame rails. On each side, replace the top
10mm (head) bumper core bolt, and tighten (Fig.EE —

28. Working on the driver's side only, and using the lower pre-existing hole in the rear brace as a template, drill a ½"
hole through both sides of the frame rail. Use the upper pre-existing hole in the rear brace as a template and drill a ½"
hole through the outside of the frame rail only (Fig.GG).
29. Place a ½" x 4½" bolt through the rear brace, frame rail and a ¼" x 2" x 2" backing plate. Finish with a ½" lock
washer and nut (Fig.HH). Repeat steps 28 and 29 for the passenger side.
30. Remove four ½" x 1½" bolts attaching the main receiver brace to the rear brace. Remove the upper 10mm (head)
bolt attaching the bumper core to the frame rail.
31. Place a ¼" x 1" x 2" backing plate in the frame rail. Bolt through the upper rear mounting point on the rear brace
using a ½" x 1½" bolt and ½" lock washer (Fig.II).
32. Break the wire off the backing plates using a pair of pliers (Fig.JJ).
33. Reinstall the bumper core and replace the bolts attaching the main receiver brace to the rear braces. Note: replacing
the bumper core bolts requires a universal extension. Tighten all bolts to the bolt torque requirements found at the end of
this document.
