Installation Manual

3. Turn cam arm adjustment nut inside cam arm yoke with fingers until it contacts surface of yoke. Turn outside nut

with a 1 1/2” wrench tight against yoke to lock adjustment.

4. Repeat Step 3 for the other side.

NOTE: From time to time it may be necessary to use a different chain link to properly level tow vehicle and trailer due

to weight changes in tow vehicle or trailer, or trunnion wear. Any time a different link is used, the cam arm must

be readjusted. Level tow vehicle per Installation Instructions for Weight Distribution. Recheck alignment

periodically. 1” Lock washers may need to be replaced after multiple uses.

MAINTENANCE:

1. Do not use grease on cam and cam arms. A light coating vaseline may be used to reduce noise. The Dual Cam was

designed to use metal-to-metal friction. Heavy greasing of the cam and cam arm surfaces will affect performance. If

noise is offensive, a very light coating of lubricant, such as Vaseline, may be used. Tongue weights over 1,200 lbs.,

may require a light coating of lubricant to reduce friction and prevent excessive wear.

2. Check for excessive wear on any contact surfaces and replace if necessary.

2. Check mating of Integrated Cam with cam arm. If not mated squarely, rap button of cam arm with hammer to obtain

alignment (see below).
