Eaz-Lift's Trekker is the perfect combination of premium weight distribution and sway control in an easy to install hitch. Trekker utilizes Adaptive Sway Technology which goes above and beyond that of the competitors' weight distribution hitches. When towing and challenged with wind gusts and passing trucks, the Trekker reacts and increases resistance as needed! During sharp turns and maneuvering, when sway control is unnecessary, the Trekker disengages sway control completely for improved handling. When towing in dangerous conditions, such as slippery or icy roads, sway control is unwanted. Trekker's easy on/off sway control makes it a breeze to manually disengage. This feature also comes in handy when hooking-up and unhooking. Includes high-low shank.
