When towing in a straight line, the spring bars on either side of the trailer's A-frame are locked in position, creating a rigid connection between tow vehicle and trailer that 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.\r\n\r\nHowever, when cornering manoeuvres are required, the cams automatically slide out of their fixed position to permit full radius turns. When the manoeuvre is short and abrupt, like 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.\r\n\r\nThe advantage of the Dual Cam system is its ability to prevent sway in addition to resisting it, holding down the start of swaying activity while still allowing free and easy vehicle and trailer interaction. It's installed on the trailer, so it doesn't require adjustment every time the tow vehicle and trailer are hooked up, unless hitch weight or tow vehicle loading are changed.\r\n\r\nThe Dual Cam HP is fitted in conjunction with any Heavy Duty Hayman Reese Weight Distribution System that includes high performance spring bars with cams.
