Adding a Snow Plow or Similar
Equipment
Before installing a snow plow on your vehicle, here are
some things you will need to know:
Notice: If your vehicle does not have the snow
plow prep package, adding a plow can damage your
vehicle, and the repairs would not be covered by
warranty. Unless your vehicle was built to carry
a snow plow, do not add one to your vehicle. If your
vehicle has the snow plow option called RPO VYU
(snow plow prep package), then the payload
your vehicle can carry will be reduced when a snow
plow is installed. Your vehicle can be damaged if
either the front or rear axle ratings, or the GVW,
are exceeded.
Q:
How do I know if my vehicle can handle a
snow plow?
A:
Some vehicles are built with a special package,
called RPO VYU (snow plow prep package). If
your vehicle has this option, you can add a plow
to it, provided certain weights, such as the
weights on the vehicle’s axles and the GVW,
are not exceeded.
Q:
How heavy can a snow plow safely be?
A:
The plow your vehicle can carry depends on many
things, such as:
• The options your vehicle came with, and the weight
of those options,
• The weight and number of passengers you intend
to carry,
• The weight of items you have added to your
vehicle, like a tool box or truck cap,
• The total weight of any additional cargo you intend
to carry.
Say, for example, you have a 700 lb (318 kg) snow
plow. The total weight of all occupants and cargo
inside the cab should not exceed 300 lb (135 kg).
This means that you may only be able to carry
one passenger. But, even this may be too much if
you have got other equipment already adding to the
weight of your vehicle.
