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
IV 2 5/16 in.
II and III 2 in.
I 1 7/8 in.
2. Select the appropriate trailer ball to
match or exceed the gross
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.
NOTICE
Only use a ball mount attachment
specified for the Toyota 4runner.

MATCHING TRAILER BALL HEIGHT TO
TRAILER COUPLER HEIGHT
No matter which class of tow hitch ap-
plies, for a safe trailer hookup, the trailer
ball setup on must be the proper height
for the coupler on the trailer.
BRAKES AND SAFETY CHAINS
Toyota recommends trailers
D
brakes that conform to any applica-
ble federal and state/provincial regu-
lations.
A safety chain must always be used
D
between the towing vehicle and the
trailer. Leave sufficient slack in the
chain for turns. The chain should
cross under the trailer tongue to
prevent the tongue from dropping to
the ground in case it becomes dam-
aged or separated. For correct safety
chain procedures, follow the hitch or
trailer manufacturer's recommenda-
tions.
