50mm tow ball in zinc-plated steel, manufactured to Australian standard dimensions for use with 50mm trailer couplings — the standard size for the majority of Australian trailers, boats, caravans, and agricultural equipment. Drop-in replacement for worn or damaged tow balls on standard tow bars.

Includes the tow ball, shank, and retaining nut. Confirm your tow bar's ball mount hole diameter and shank length requirements before ordering — most Australian tow bars take a standard 20mm shank, but heavy-duty aftermarket bars may vary. Not rated for off-road or extreme load applications without confirming the load rating matches your trailer's GTM.
