Your route is planned and the trails are calling, but before you can cover any ground, you need to start with a solid connection between your tow vehicle and trailer. The CURT round bar weight distribution hitch with integrated lubrication offers a smooth ride and level towing with its heavy-duty components and built-in lubrication system. From travel trailers to popup campers, the CURT WD hitch is the perfect camping companion to let you Bring It. The strength of the round bar WD hitch begins with its heavy-duty, formed steel head. The formed construction allows for a precise design and supplies the durability needed to manage the weight of heavy trailers. Something unique to the weight distribution hitch is its grease zerk fittings, built directly into the head, allowing for easy, continuous lubrication at the spring bar mounting location. The spring bars are installed from the underside of the WD head and are made with forged steel for optimum strength. Like other CURT weight distribution hitches, the round bar hitch comes with a highly adjustable shank and chain hookup brackets for the perfect amount of tension to level the load. The shank fits any 2" x 2" receiver tube opening, making it compatible with most class 3, class 4 and class 5 trailer hitches. The head is also compatible with our 2-1/2" weight distribution shanks to match the heaviest of class 5 hitches. The hookup brackets and spring bars of the CURT WD hitch use chains and a simple snap-up design for easy setup and adjustment. This particular round bar weight distribution hitch offers a towing capacity ranging from 10,000 to 14,000 lbs. GTW and 1,000 to 1,400 lbs. TW. It comes with installation hardware, a pre-torqued 2-5/16" trailer ball and a sway control unit #17200. To protect this WD hitch on the way to your next destination and beyond, it also comes with a durable carbide powder coat finish.
