SAFETY DEFINITIONS
WARNING
Do not exceed GVWR or GAWR including
blade and ballast. The rating label is found on
driver-side vehicle door cornerpost.
WARNING
Indicates a potentially hazardous situation
that, if not avoided, could result in death or
serious personal injury.
WARNING
To prevent accidental movement of the blade,
always turn the ON/OFF switch to OFF
whenever the snowplow is not in use. The
control indicator light will turn off.
CAUTION
Indicates a potentially hazardous situation
that, if not avoided, may result in minor or
moderate injury. It may also be used to alert
against unsafe practices.
WARNING
Remove blade assembly before placing vehicle
on hoist.
NOTE: Indicates a situation or action that can lead
to damage to your snowplow and vehicle or other
property. Other useful information can also be
described.
CAUTION
Refer to the Kit Selection Guide for minimum
vehicle recommendations and ballast
requirements.
SAFETY PRECAUTIONS
Improper installation and operation could cause
personal injury, and/or equipment and property
damage. Read and understand labels and the
Owner’s Manual before installing, operating or making
adjustments.
PERSONAL SAFETY
• Remove ignition key and put the vehicle in park or
in gear to prevent others from starting the vehicle
during installation or service.
WARNING
• Wear only snug-fitting clothing while working on
your vehicle or snowplow.
Lower blade when vehicle is parked.
Temperature changes could change hydraulic
pressure, causing the blade to drop
unexpectedly or damaging hydraulic
components. Failure to do this can result in
serious personal injury.
• Do not wear jewelry or a necktie, and secure long
hair.
• Wear safety goggles to protect your eyes from
battery acid, gasoline, dirt and dust.
• Avoid touching hot surfaces such as the engine,
radiator, hoses and exhaust pipes.
WARNING
• Always have a fire extinguisher rated BC handy,
for flammable liquids and electrical fires.
The driver shall keep bystanders clear of the
blade when it is being raised, lowered or angled.
Do not stand between the vehicle and the blade
or within 8 feet of a moving blade. A moving or
falling blade could cause personal injury.
WARNING
Keep hands and feet clear of the blade and Aframe when mounting or removing the
snowplow. Moving or falling assemblies could
cause personal injury.

WARNING
CAUTION
Read instructions before assembling.
Fasteners should be finger tight until
instructed to tighten according to the torque
chart. Use standard methods and practices
when attaching snowplow including proper
personal protective safety equipment.
Gasoline is highly flammable and gasoline
vapor is explosive. Never smoke while working
on a vehicle. Keep all open flames away from
gasoline tanks and lines. Wipe up any spilled
gasoline immediately.
Be careful when using gasoline. Do not use gasoline
to clean parts. Store only in approved containers away
from sources of heat or flame.

INSTALLATION INSTRUCTIONS
3. Replace the tow hook into the frame and install
and tighten only the single rear tow hook fastener
at this time. If necessary, loosely install a front tow
hook fastener to maintain tow hook hole alignment
while tightening the rear fastener. Remove the
front fastener after tightening the rear fastener.
NOTE: For easier assembly and installation,
vehicle and all snowplow components should be
on a smooth, level, hard surface, such as concrete.
4. Beginning on the driver side, remove the two sway
bar bracket fasteners and remove the retained
nutclips from the sway bar bracket. Allow the sway
bar bushing and U-bracket to separate from the
vehicle frame.
1. Remove bumper by first detaching any electrical
cords attached to bumper (diesel engine and
vehicles with fog lamps). Remove the bumper
fasteners and save for reinstallation.
WARNING
5. Remove the U-bracket from the sway bar bushing.
Enlarge the two holes in the U-bracket with a
17/32" drill to allow clearance for 1/2" cap screws,
and save for later installation.
Removing the BlockerBeam™ without
installing snow plow attachment hardware may
affect air bag deployment in a crash. Do not
operate the truck unless either the
BlockerBeam or the snow plow attachment
hardware is installed on the vehicle.
Enlarge to 17/32"
2. Vehicle is equipped with a BlockerBeam between the
frame horns and behind the bumper. Disconnect the
rubber air deflector from the BlockerBeam, then
detach and remove the BlockerBeam and tow hooks
from the truck frame. Save tow hooks and three tow
hook fasteners for reinstallation later in this instruction.
Remove and save nutclips and cap screws for
reinstallation on bumper mounting bracket in Step 6.
Loosely reattach the rear cap screw and retainer nut
to each side of the BlockerBeam to prevent loss.
Affix tag 66871 to the BlockerBeam using the cable
tie provided. BlockerBeam must be reinstalled if plow
attachment kit is ever removed
and must be transferred
when vehicle is sold
or traded.
6. Install the bumper mounting bracket to existing
frame holes using the self-tapping screw, and the
1/2" x 1-1/2" cap screw with handle, flat washer
and locknut. Use only the rear-most holes in the
bracket. Tighten these fasteners at this time, then
install nutclip taken from BlockerBeam.
Remove and save
nutclip and cap
screw.
Attach to
BlockerBeam
for storage.

7. Position the pushplate against the vehicle frame with
tow hook and sway bar holes aligned. Install, but do
not tighten, the 1/2" x 1-3/4" cap screw, flat washers
and locknut through the front of pushplate and
existing hole
in outboard
side of frame
to support
the pushplate
in position.
10. Repeat Steps 3–9 on passenger side using
1/2" x 2" cap screws in both holes of the sway bar
bracket.
11. Loosely attach cross bar between both pushplates
using 1/2" x 1-3/4" cap screws, flat washers and
locknuts. Set the center-to-center measurement
between the connecting arms to 29-1/8", and
tighten these four cap screws and locknuts.
8. Install, but do not tighten, the remaining two tow
hook fasteners.
CAUTION
Protect radiators and cooling lines against
damage while drilling holes in frame.
12. With mount firmly against truck frame, drill two
17/32" holes through the side of the frame at the
rear of pushplate using holes in the pushplate as
locators. Fasten securely using two
1/2" x 1-1/2" cap screws with handles, flat
washers and locknuts.
9. Insert the sway bar spacer between the pushplate
and sway bar bushing. Loosely attach rear of
pushplate using cap screws (1/2" x 1-3/4" in rear
hole and 1/2" x 2" in front hole), one flat washer on
top of sway bar bracket and one on bottom of
modified U-bracket and locknuts. Cap screws and
washers may be installed up from below with nuts
and washers on top of sway bar bracket as
required for clearance.
Drill 17/32" holes,
then fasten.
13. Tighten tow hook fasteners first, then tighten sway
bar bracket fasteners. Next, tighten the
1/2" x 1-1/2" cap screw and locknut passing
through the frame side.

14. Drill one 17/32" hole through the inboard side of
the frame at the front of the pushplate, just ahead
of the radiators, using the hole provided in the
pushplate as the locator. Fasten securely using
one 1/2" x 1-3/4" cap screw, flat washers and
locknut.
18. Reinstall the bumper using existing hardware at
the frame horns and at the bumper mounting
brackets. Reattach any electrical cords removed
during bumper removal.
19. The air dam can be notched generally as shown to
clear the connecting arms if necessary.
Drill 17/32" hole,
then fasten.

20. Attach front of rubber air deflector that was
originally attached to the BlockerBeam™ to the
bottom of the air dam with the four provided cable
ties.
15. Repeat Steps 12–14 on the passenger side.
Cable Ties
16. Tighten all fasteners at this time per torque chart.
17. Use cable ties to tie up cooling lines that may
contact parts just installed. It is important to
provide sufficient clearance between all portions of
the cooling lines and the snowplow pushplate
components.
NOTE: After five to ten hours of snowplow usage,
retorque all pushplate assembly fasteners.
NOTE: Use anti-chafing material in those
situations where sufficient clearance cannot be
maintained.
