Bulldog has been a trusted name in trailer hitch hardware for decades — a brand built on the premise that towing components need to be engineered to spec, rated accurately, and built to last through years of hard use. The Bulldog collection at Angler's Pro Tackle carries the brand's Interlock hitch ball lineup, the essential trailer coupling hardware that connects your tow vehicle to your boat trailer, utility trailer, or any towable load requiring a reliable, rated ball mount connection.
The collection covers two diameter and capacity configurations to match the trailer coupler size and towing capacity requirements of your specific rig. The 1-7/8-inch diameter Interlock Hitch Ball is rated at 3,500 pounds and is the standard size for smaller boat trailers, personal watercraft trailers, utility trailers, and lightweight towable loads — available in HD zinc finish for corrosion resistance. The 2-5/16-inch diameter Interlock Hitch Ball steps up to a 7,500-pound capacity rating for larger boat trailers, heavier utility trailers, and towing applications that demand a larger coupler size and higher weight rating. Both sizes use Bulldog's Interlock design for secure, rattle-reducing connection between ball and coupler, and both are available in HD zinc finish that holds up to the weather, road salt, and marine environment exposure that boat trailer hardware deals with every season.
Matching your hitch ball diameter to your trailer coupler size is non-negotiable for safe towing — using the wrong size risks coupler separation under load. If you run a bass boat, pontoon, jon boat, or any trailerable watercraft, keeping a spare Bulldog hitch ball on hand is basic towing preparedness.
