TRAILER BALL
Follow these easy steps to properly deter-
mine the correct trailer ball for your ap-
plication:
1. Determine the correct trailer ball size
for the trailer coupler. Most couplers
are stamped with the required trailer
ball size. The sizes you will most likely
find stamped on the coupler are:
Trailer class Typical trailer ball size
III and IV 2—5/16 in.
II 2 in.
I 1—7/8 in.
2. Select the appropriate trailer ball to
match or exceed the gross trailer
weight rating of the trailer. The trailer
ball load rating should be printed on
the top of the ball.
3. When mounted in the ball mount, the
threaded ball shank must protrude be-
yond the bottom of the lock washer
and nut at least 2 threads. The trailer
ball shank must be matched to the ball
mount hole diameter size.
