Rated to tow up to 10,000 pounds gross trailer weight, this hitch ball promises reliable strength that gives me real confidence on the road, whether I’m hauling heavy equipment, trailers, or recreational gear. Knowing it’s constructed from hot-forged steel reassures me that it can handle tough towing demands without compromising safety or durability.

This level of secure installation is critical for peace of mind, especially when towing heavy trailers over long distances or rough terrain.

Finally, safety is clearly a priority with this CURT trailer hitch ball. It has been tested to meet U.S. VESC specifications, which means it adheres to stringent safety standards.
