Step 4 – Assemble the Sway Brackets
Tools Needed:
• 9/16” Box-end or socket wrench (Link plates)
• 5/8” Box-end or socket wrench (L-brackets)
• Measuring tape
Sway Bracket Location
1. Install the bracket assemblies between 25” — 30” from the center
of the coupler. (Figure 6) This range should allow you to avoid
most obstructions on the trailer tongue like battery supports or
propane tanks.
2. Measure along the frame from the center of the coupler to the
center of the brackets.
3. Both brackets should be the same distance from the coupler.
4. If necessary, relocate items on the frame to allow installation of
the brackets within this range.
Á
CAUTION
Do not use an impact wrench to tighten the link plate
or L-bracket bolts.
Assemble the Link Plates
Partially assemble the brackets:
1. Insert one 3/8” x 3-1/2” bolt through the outside link plate going
the opposite direction as the L-bracket mounting bolts.
2. That same bolt should pass through the top hole of the inside link
plate.
3. The bolt heads should fit completely into the recessed slots.
4. Slide a 3/8” split washer onto the frame bolts and thread on
a 3/8” nut a few turns. Do not use lock nuts on these bolts.
(Figure 7)
Identify your coupler style and follow the correct step for your style.

Typical Installation - Top-mounted Couplers
1. Slide the link plate assembly down over the frame hanging from
the top bolt with the mounting bolts facing out.
2. Insert the second 3/8” x 3-1/2” bolt through the open hole closest
to the bottom of the trailer frame. (Figure 9)
3. Insert the bolt head into the slot and add a 3/8” lock washer and
thread a 3/8” nut onto the end of the bolt.
Inverted or Upside-Down Installation – Bottom-mounted
Couplers, V-nose Trailers
Install the assembly upside-down if you have a trailer with a bottom-
mount coupler, V-shaped nose, or any other obstacle that prevents
them from being installed right-side up.
