The RAM 12.5K is a cast A-frame trailer coupler rated for 12,500 lb, built for a 2 5/16-inch hitch ball. Its cast head has a flat top and two straight corners, a shape RAM says helps the coupler self-adjust so hitching and unhitching go easier. It uses a spring-loaded collar and a low-profile latch, and it carries the SAE markings required by standard J684. Buyers rate it highly; the main gripes are the raw finish and the need to clean off light rust and oil before install.
