You need to get a hitch that is rated for the load you are going to pull. They are rated by different classes 1 thru 5 with 1 being the lightest. Most are receiver hitches that permit different uses, tow ball, D-rings, bike racks, etc. If you are pulling a trailer, dont forget you will need a wiring harness too. Do a little research to learn more. Hitches are available many places, Amazon, E-bay, and other web sites. If you are on a tight budget check out used hitches.
