How do you tell the class of a receiver hitch?

The class of a receiver hitch is determined by its weight capacity and design specifications. There are five classes, ranging from Class I (up to 2,000 lbs) to Class V (up to 20,000 lbs or more), each with different receiver sizes and weight ratings. You can identify the class by checking the hitch's label or sticker, which usually indicates its class rating, or by measuring the hitch opening size (e.g., 1.25 inches for Class I and 2 inches for Class III and above). Always refer to the manufacturer's guidelines for accurate identification and usage.
