You can view drum brake surge couplers for 2-5/16-inch balls by clicking on the linked page. Simply click on the filters to select the features you want, such as weight rating, bolt-on versus weld-on installation, and a-frame or straight tongue trailer design. For example, for a 20K-rated coupler with electric lockout for a 4-inch wide straight tongue you can use # T4854020 from Titan.
