A hitch receiver is a crucial component used in towing applications, designed to attach a trailer to a vehicle. It is typically mounted to the rear of a vehicle and comes in various sizes and weight capacities to accommodate different towing needs. The receiver allows for easy installation and removal of a hitch ball or other towing accessories. Hitch receivers are classified by their size, with common types including Class I, Class II, Class III, and Class IV. Each class indicates the maximum weight the receiver can handle, ensuring safe towing. Proper selection and installation of a hitch receiver are essential for effective and secure towing.
