The most popular towing aid in Australia which is rated for trailers that have a ball weight of between 135Kg and 275Kg (suitable for most popular caravans). Weight Distribution Systems (WDS) restore the geometry of the tow vehicle (such as a ute) to its natural state. A WDS transfers the weight from the rear wheels of the ute to two places: the front wheels of the ute and the wheels of the trailer. To put it simply, a good WDS will level the link between trailer and ute so it is in parallel alignment to the road. When towing a trailer, the trailer’s total ball weight is applied to the rear of your vehicle. When this happens, the front suspension of your vehicle is raised because of the added rear weight. Towing like this can cause excess swaying of your trailer, reduced steering and breaking responsiveness, less traction and headlights that beam upwards instead of down onto the road in front of you. Over time, you may also experience reduced fuel economy and increased tyre wear (especially on the rear tyres). Hayman Reese have a number of WDS’s available to improve your control over your vehicle while towing and reducing the amount of sway you experience. It has a durable and light cast steel head. Its round, hook style spring bars have integrated cams which are ideal for caravans with 6” deep A-frames. It also features a Hex Cam adjustment washer which allows for up to six head-angle adjustments. Specifications: Suitable for ball weights between 135kg - 275kg.
