1 ¼" hitches come in class 1 and class 2. Class 1 has a tongue weight rating of 200lbs and class 2 has a rating of 300lbs. You need a minimum 300 lb tongue weight rating, or class 2 hitch, to use to use the 4-bike Freedom or 4-bike Freedom SuperClamp racks. Most of our vehicle racks will work with a 200 lb tongue weight rating, or a class 1 hitch. If you are using a class 1 hitch, be sure to check the tongue weight limit before using your rack.
2" hitches typically come in a class 3 or higher, and will handle any of our hitch racks.
