Step 4 - Sway Control Bracket Assembly
Sway Bracket Location
Measure from the center of the coupler along the trailer frame, and place a mark at
30” on both sides. This is the center mark for the sway control bracket assembly.
Make sure there are no gas lines, brake lines, or electrical wires located along the
frame that could be affected by the installation of the link plates. If so, re-route
or avoid the lines so their function will not
be disrupted or damaged by the link plate
installation.
Placing the sway control brackets centered at
30” back puts the least amount of stress on the
trailer and hitch components, and provides the
most comfortable ride. Sway brackets should be
placed at 30” whenever possible.
In some cases where there is an obstruction at
30” that cannot be avoided, like a battery rail
or propane tank support, the brackets may be
moved forward up to a minimum distance of
27” from the center of the coupler. See Figure 6.

Assemble Link Plates
Insert one 1/2” x 4” bolt through the single hole
of the outside link plate so it goes through in the
opposite direction of the L-bracket mounting studs.
Insert the same bolt through the single hole on the
inside link plate. Slide on a split washer, and then
thread on a 1/2” nut a few turns. See Figure 7.
