When towing with heavy commercial trucks, higher loads or driving over rough and uneven Australian terrains, this override ring coupling used in conjunction with a pintle hook, helps to secure your trailer and suits Australian Standard AS4177 as it states the 50mm tow ball to have a maximum capacity of 3500kg loaded trailer mass. This high quality and durable 75mm ring coupling with the overriding feature, is the sliding shaft and spring inside attached to the tow ball housing. This spring allows for when the driver applies brake pressure, it pulls on the brake cable and thus braking system suited for hydraulic and mechanical set ups.
