Frequently Asked Questions
Q: What vehicles and trailers is this 50mm tow ball hitch coupling compatible with?
A: This 50mm tow ball hitch coupling with M22 thread shank is compatible with a wide range of vehicles fitted with a standard towbar that accepts an M22 thread. It suits caravans, RVs, campervans, boat trailers, and general equipment trailers that use a standard 50mm coupling head — the most common size in Australia, the UK, and Europe.
Q: How do I install the M22 thread tow ball shank?
A: Installation is straightforward. Insert the M22 threaded shank through the towbar mounting hole and secure with the provided nut, tightening to the torque specification recommended for your towbar. Always verify your towbar's rated capacity matches or exceeds the 3.5T rating of this coupling before use.
Q: What is the maximum towing capacity of this hitch coupling?
A: This heavy-duty tow ball hitch is rated to 3.5 tonnes (3,500 kg), making it well-suited for towing fully loaded caravans, boat trailers, and equipment trailers. Always ensure your vehicle's towing capacity and towbar rating also meet or exceed the load being towed.
Q: Is this tow ball suitable for boat trailer towing near saltwater environments?
A: The silver steel finish provides a degree of surface protection, but we recommend rinsing the hitch with fresh water after saltwater exposure and applying a suitable metal protectant spray to maintain the finish and extend service life.
