Sway Bracket Assembly

Sway Bracket Location:

Measure from the center of the coupler along the trailer frame, and place a mark at 32” on both sides. This is the center mark for the sway bracket assembly.

Check around the trailer frame and make sure that there are no gas lines, brake lines, or electrical wiring that could be affected by the installation of the link plates. If so, make sure these are re-routed or avoided and will not be disrupted or damaged by the link plate installation.

Placing the sway brackets centered at 32” 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 32” whenever possible.

In some cases where there is an obstruction at 32” that cannot be easily moved, like a battery rail or propane tank support, the sway brackets may be moved forward toward the coupler to a minimum distance no closer than 27” from the coupler center. See figure 6.

Caution

Do not use an impact wrench to tighten link plate or L-bracket bolts.

Assemble Link Plates:

Insert two 1/2” x 1-1/2” bolts through the outside link plate from the back side. The head of the bolts should fit completely inside the pocket on the back.

Insert one 1/2” x 3-1/2” bolt through the single hole on the outside link plate, and the single hole on the inside link plate. The head of the bolt should fit into the pocket of the outside link plate.

Slide on a split washer, and then thread on the 1/2” nut a few turns. See Figure 7.

Identify your coupler style. See Figure 8.

If your trailer has a top-mounted coupler, drop the link plates over the top of the frame and insert the bottom bolt through the hole closest to the bottom of the trailer frame. Slide on a split washer, then thread a 1/2” nut onto the bolt. See Figure 9.

If your trailer has a bottom-mounted coupler, is a V-nose trailer, or has some other obstacle that makes using the hitch difficult with the brackets mounted in the standard position, install the link plates upside down on your frame. Slide the assembly up from the bottom. Hold the bolt up tight to the bottom of the frame and thread the top bolt through the link plate hole closest to the top of the trailer frame. Slide on a split washer, then thread a 1/2” nut onto the bolt. See Figure 10.

There should not be much space between the trailer frame and the link plate bolts on the top or bottom of the frame. Move electrical or propane lines if necessary. See Figure 11.

Tightening only one nut without first pinching the link plates to the frame may cause the inside link plate to bend when torqued completely. It may also give you a torque wrench reading that indicates the link plates are tight, even though they are not. See Figure 12b.

After both nuts are finger tight, use a torque wrench to tighten all link plate bolts to 65 ft‑lbs torque.

L-bracket Installation:

For the first setup, slide the L-brackets onto the link plate studs with the toe facing away from the trailer. Leave 2 holes showing at the top above the studs and two below. They may need to be adjusted up or down later to get good weight distribution. Thread on the nylock nuts and tighten them. See Figure 13.

When weight distribution adjustment is complete these nuts should be torqued to between 70 - 75 ft‑lbs.
