A Class IV hitch is a type of towing hitch designed for heavy-duty applications. It can typically handle a maximum weight of 10,000 pounds for towing and a maximum tongue weight of 1,000 pounds. This makes it suitable for larger trailers, such as fifth-wheel trailers and boat trailers, which require more robust support. Class IV hitches are commonly found on trucks and SUVs that are used for towing recreational vehicles or equipment. They usually feature a 2-inch receiver opening, allowing for various attachments and accessories. Proper installation and weight distribution are essential for safe towing with a Class IV hitch.
