2. Determine What Class
Weight Carrying (WC) Receiver Hitch You Need.
Trailer hitches come in a variety of shapes and sizes for various
applications. Generally speaking, trailer hitches are classified either
weight-carrying or weight-distributing. The type best for you depends entirely
upon the tow vehicle and trailer size and weight.
Weight-carrying (WC) type of
hitch is used in applications where trailer weight is up to and including a
maximum of 3,500 lbs., and where the weight and suspension of the tow vehicle
can accommodate that load. The tongue weight (TW) is carried directly on the rear of
the tow vehicle and on the hitch.
Weight-distributing (WD) An
attachment, (sold separately) which slides into a Class 3/4 or Class 5
weight carrying (WC) receiver hitch, and redistributes hitch tongue weight (TW).
Weight distributing hitches are normally used for
heavier trailers up to 10,000 lbs. Typically uses 2 spring
bars, one on each side of the trailer to lift up and apply leverage to the tow
vehicle, thereby redistributing tongue weight from the rear axle to the front.
This provides more vehicle stability while towing. Weight distributing hitches
currently come in two configurations: One with square bars that hook to the
center of the ball mount, called trunnion bars, and one with round bars that
slide into the bottom of the ball mount, called round bars.
