The SwayPro hitch from Blue Ox gives your customers worry-free sway prevention in a weight distributing hitch unlike any other hitch on the market: The preset hitch head employs caster in the head to keep the trailer in line with the tow vehicle. SwayPro’s rotating latches pre-load the true spring steel bars, providing a center forcing that prevents sway caused by wind, passing vehicles, and winding roads. SwayPro’s spring steel bars work without friction points to prevent trailer sway in any weather, including rain and snow. SwayPro is quiet, you will not hear any of the noises created by hitches that use friction. SwayPro can be used with nearly any tow vehicle and any trailer. There is no need to buy a new hitch when changing trailers. Simply buy new spring bars that are rated for the tongue weight of the new trailer.
