Key Features & Benefits
- 3.5 tonne rated — rated to 3,500kg gross trailer mass, suitable for towing heavy trailers, caravans, boat trailers and car carriers within the vehicle’s towing capacity.
- 50mm ball diameter — standard Australian tow ball size compatible with virtually all trailer couplings sold in Australia.
- 7/8″ (22mm) shank — standard shank diameter that fits most Australian tow bar tongue holes and hitch receivers.
- Chrome-plated finish — polished chrome provides a smooth, low-friction surface for the coupling to rotate on, and resists corrosion from rain and road spray.
- Australian Standard approved — manufactured and tested to meet Australian Standards for tow ball strength and dimensions.
When to Use This Tow Ball
The R1830 is a universal 50mm tow ball suitable for most towing applications in Australia. Check your vehicle’s towing capacity before selecting a trailer — the 3.5 tonne rating is the tow ball limit, but your vehicle may have a lower towing capacity. Protect the chrome surface when not towing with a R1856 tow ball cover to prevent corrosion and keep the coupling clean.
