Sway Controllers

Trailer sway is one of the most common concerns for those who tow. Trailer sway can be influenced by poor weight distribution, tyre pressure, towing speed and suspension. But most commonly it is caused by strong winds and wind buffets from large vehicles such as trucks.

Complete sway control can be obtained by fitting a Hayman Reese Friction sway controller. Hayman Reese sway controllers are designed to be used in conjunction with a weight distributing systems and prevent trailer sway by restricting and damping the movement between the tow hitch and the trailer.

Sway controllers are not suitable for use with trailers fitted with older surge or override trailer braking systems

The Friction Sway controller manages sway by using friction material, (similar to what is used in modern disk brake pad) and a sliding bar with an adjustable lever to regulate the movement of the trailer.

All current Weight Distribution System heads come with a mounting tab to enable use of this sway controlling device. For all older Weight Distribution Systems a melting tab is required to be welded to the head. This can be done by your Hayman Reese distributor.

To allow for easy reversing, Hayman Reese suggests that the Friction Sway Controller is removed and thus us a quick and easy task.

A Friction Sway Controller can be used with Weight Distribution Systems 550lb, 600lb, 750lb & 800lb models, and are perfect for trailers up to a 200kg ball weight.

The Hayman Reese Dual Cam High-Performance™ Sway Controller is the premier method of controlling sway,and the only product of its kind in the Australian market.

Unlike other sway controllers, this approach works to control sway from the start rather than just resisting sway once it’s begun. When towing in a straight line, the spring bars on either side of the trailer’s A-frame are locked in position.This essentially creates a “rigid” connection between tow vehicle and trailer and minimises the effects of induced sway caused by high crosswinds or passing vehicles. Usually the spring bars ride in a locked-in position, even on fairly sharp curves.

However, when cornering manoeuvres are required, the cams automatically slide out of their fixed position to permit full radius turns. Yet when the manoeuvre is short and abrupt, like that encountered in the event of a sudden swerve or a wheel dropping off the road, the spring bars seek a straight-line towing angle that helps the tow vehicle retain control.

The advantage of the Dual Cam system is its ability to prevent sway in addition to sway resistance. It works to hold down the start of swaying activity while at the same time allowing free and easy vehicle and trailer interaction. Another advantage of the Dual Cam system is that it’s installed on the trailer and therefore doesn’t require adjustment every time the towing vehicle and trailer are hooked up, unless hitch weight or tow vehicle loading are changed.

The Dual Cam HP is fitted in conjunction with any Heavy Duty Hayman Reese Weight Distribution System that includes high performance spring bars with Cams. It is ideal for any trailers with a ball weights in excess of 200kg.
