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.

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.

vehicle begins to brake, the trailer pushes against the hitch ball,
consequently activating the trailer brakes.

and also carries the coupler assembly.

TRAILER TONGUE
LOAD The amount of trailer (conventional) weight pressing down on the
tow vehicle hitch.

WEIGHT-DISTRIBUTING

trailer tires and the tow vehicle front tires. Strongly recommended

5,000 lbs.

WIRING HARNESS

system to the trailer’s system.
