Class 1 Trailer Hitch Ball
Choosing a class 1 trailer hitch ball means matching a light-duty towing setup to the trailer coupler, the receiver opening, and the vehicle’s actual weight limits. A class 1 receiver is generally used for small utility trailers, bike racks, and lightweight cargo carriers, so the ball mount and ball diameter have to work together without pushing the gross vehicle weight rating, axle rating, or tongue weight beyond safe bounds. The right purchase starts with the shank size, the ball capacity, and the coupler fit.
The direct answer
A class 1 trailer hitch ball is the removable spherical component that sits on the ball mount and engages the trailer coupler. For this light-duty class, the immediate answer is usually a 1-7/8-inch or 2-inch ball, but the coupler stamping on the trailer is the deciding factor. The shank diameter must also match the hole in the ball mount, and the ball’s rated capacity needs to cover the loaded trailer weight as well as the tongue weight applied at the coupling point.
The broader towing configuration matters more than the receiver class label alone. A compact crossover or sedan with a class 1 receiver may have a low gross vehicle weight rating and a limited combined weight rating, so even a properly fitted ball does not increase what the vehicle can control. Check the payload, axle rating, and the trailer’s loaded weight before purchase. The ball is only one link in that entire weight-handling chain.
