It’s a good match when your vehicle and hitch tongue ratings meet or exceed the mount’s capacities and when a 1-7\/8\" coupler and 2\" receiver are required. Always ensure the lowest-rated component in your tow chain determines your safe towing limits.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this ball mount fit a 2\" receiver?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
