The Eaz-Lift ReCurve R3 is a weight distribution hitch with a 600 lb. tongue weight rating that features adjustable sway control. By simply adjusting the clamp, you can decide how much sway control is exerted on the trailer. The ReCurve R3 will distribute the weight of your trailer across the axles of the tow vehicle and provide as much sway control as you choose. Or, turn the sway control completely off in dangerous or icy road conditions. Its top-loading spring bars give it more ground clearance than other hitches, and the streamlined design makes the hitch and the trailer move as one, while creating a sleek look. The R3 Weight Distributing Hitch Kit is constructed of heavy-duty steel and has a 6,000 lb. gross trailer weight rating. Includes a 2-inch hitch ball with an 8,000 lb. rating.
