TOWING
GLOSSARY
5TH WHEEL
HITCH Located just forward of the rear axle centerline, this hitch uses a king pin to serve
as the pivot point for the trailer.
BALL MOUNT A bar that holds the hitch ball and is inserted into the hitch receiver. Also
commonly called a drawbar or “stinger.”
BREAKAWAY SWITCH A safety device using a trailer battery that automatically applies the trailer’s
brakes if it should accidentally become separated from the tow vehicle. A
breakaway switch may be used with both electric or surge trailer brake systems.
BUMPER HITCH A reinforced bumper designed to accommodate a hitch ball.
ELECTRIC TRAILER
BRAKES When the brakes on a tow vehicle are applied, an electric current is sent to an
actuator which applies the trailer’s brakes.
ELECTRIC TRAILER
BRAKE CONTROLLER A device that controls the electric trailer brakes.
GOOSENECK HITCH Located just forward of the rear axle centerline, this hitch uses a ball to serve as
the pivot point for the trailer.
GROSS AXLE
WEIGHT RATING (GAWR) The maximum amount of weight each vehicle axle (front and rear) is designed to
safely carry.
GROSS COMBINED
WEIGHT RATING (GCWR) The maximum allowable combined weight of the vehicle and trailer, including
passengers and all cargo.
GROSS VEHICLE
WEIGHT RATING (GVWR) The maximum allowable weight of the vehicle, including passengers, cargo, fuel,
hitch, trailer tongue load, and any optional equipment.
KING PIN
LOAD The amount of trailer (5th wheel or gooseneck) weight pressing down on the tow
vehicle hitch.
HITCH BALL
A ball that connects the trailer to the tow vehicle hitch and provides the means
by which the trailer pivots during cornering. Available in a number of sizes and
weight capacities, it must correspond to the trailer coupler size, and have a
sufficient capacity rating for the trailer being pulled.
RECEIVER HITCH A frame- or structure-mounted hitch with a receiver that allows removal of the
ball mount.
SAFETY CHAINS/CABLES Provides an emergency connection between the tow vehicle and the trailer,
should the trailer become disengaged for any reason.
SURGE BRAKES
Hydraulic-type braking system activated by inertia. As the tow vehicle begins to
brake, the trailer pushes against the hitch ball, consequently activating the trailer
brakes.
TRAILER TONGUE/COUPLER The part of the trailer that extends forward to meet the tow vehicle, and also
carries the coupler assembly.
TRAILER TONGUE
LOAD The amount of trailer (conventional) weight pressing down on the tow vehicle
hitch.
WEIGHT-DISTRIBUTING HITCH
SYSTEM Type of hitch system that helps shift the trailer tongue weight to all trailer tires
and the tow vehicle front tires. Strongly recommended when towing trailers with
a Maximum Trailer Weight greater than 5,000 lbs.
WIRING HARNESS
Provides an electrical connection linking the tow vehicle’s electrical system to
the trailer’s system.
