Heavy Duty TAG Towbars for Heavy Duty Vehicles TAG heavy duty towbars are made in Australia and have been specifically designed for 4x4 vehicles to increase the departure angles when used off-road making them less of a hindrance to than most OEM tow bar and ball systems that would often protrude out the back of the vehicle. Each towbar has a 50mm square hitch receiver that can be removed when not in use through a pin and clip design. The detachable design allows the ball and hitch receiver to easily be removed when you're not towing, which is not only safer for pedestrians but also eliminates theft opportunity. TAG Towbars are powder-coated to ensure good looking and long lasting protection. TAG towbars are available for most vehicles in Australia whether you need a TAG Euro Tow Bar with the classic swan neck or TAG Standard Duty Tow Bars for box trailers, small boats and bike racks or TAG+ Heavy Duty for the Big Boats, car trailers and huge caravans.
