No-Sway, no-bounce We didn't just raise the bar, but we eliminated the need for sway bars entirely. The design of the Andersen Weight Distribution Hitch eliminates the sway and bounce in your trailer, using our interconnected motion-dampening chains and sway-control ball housing system. Each WD Hitch Kit includes: an adjustable steel rack, grease-free ball and silent friction cone, anti-say plate, 2 motion-dampening tension chains and urethane springs, two sets of tongue brackets.
