The Heavy Duty Trailer Hitch Ball is a critical towing component used to securely connect trailers, RVs, caravans, utility vehicles, and agricultural machinery to towing vehicles. Manufactured through precision hot forging and CNC machining, our trailer balls ensure unmatched strength, accuracy, and long-lasting durability. Every unit is engineered for high load capacity, resistance to corrosion, and global compatibility with towing couplers.
We specialize in custom-manufactured Heavy Duty Trailer Hitch Balls in various ball diameters, thread sizes, and finishes, tailored to meet the standards of markets across North America, Europe, and Australia. Our standard surface treatment uses zinc-nickel alloy electroplating, which offers superior corrosion resistance—outperforming traditional chrome or zinc-coated finishes in salt spray and outdoor conditions.
HZF, a professional tow ball supplier in China, offers both OEM/ODM services and reliable large-volume supply for international brands, wholesalers, and trailer equipment manufacturers.
