Hitch class is used to dictate the weight capacity of the hitch mounted to the rear of the vehicle. Before purchasing a trailer hitch you need to think about the job you are trying to take on with your Tacoma. The more equipment you are hauling with your truck, the higher the hitch class you will need.
Class 3: Based on Tacoma’s towing capacities, a class 3 hitch will be the most common hitch available to these trucks. Class 3 hitches are designed to handle a gross trailer weight up to 10,000 lbs. Class 3 hitches are ideal for hauling boats and small trailers. Class 3 hitches use a 2-inch receiver which means they can accept most trailer hitch balls and accessories.
Class 4: A class 4 hitch is also very common for use with Tacomas. These hitches are rated to handle a maximum gross trailer weight of 14,000 lbs. As the step above a class 3 hitch, this class can easily handle anything you can throw at a Tacoma within range of its towing capacity. These hitches are also fitted with 2-inch receivers making them an excellent option for all workloads.
Class 5: Toyota Tacomas can be fitted with a class 5 hitch. These hitches have a gross trailer weight capacity of 12,000 lbs., but are designed to work best with weight distribution hitches. If a large enclosed trailer is being hauled behind your Tacoma, this is the hitch to reach for. These hitches are fitted with 2.5-inch Receiver hitches which leaves them dedicated to hauling trailers.
