The Class III Standard Mount Starter Kit has the towing essentials to get you started hauling and on the road. Kit includes a standard ball mount, a trailer hitch ball, and a standard hitch pin. The ball mount features a hollow steel design, providing you with ultimate strength when towing your cargo. The ball mount can be used in either the drop or rise position for towing applications depending on your requirement. Class III mounts are great for towing things like campers, boats, and trailers carrying ATVs and motorcycles. While these are common uses for this class, it is important that you know the total weight of the trailer and its contents, and that you do not exceed the recommended maximum towing capacity determined by your vehicle manufacturer.
