Why Can't Class II Accessories Be Used with Class I Trailer Hitch Receiver

Published 11/29/2017

Question:

Why is it class I receivers will not accept class II only hitches or adapters? I am ignorant on the subject as Ive never had less than a class III until now. I dont want to buy the wrong adapter and I can only get a class I for this car.

Both Class I and Class II trailer hitches have the same 1-1/4 inch receiever opening, however a Class II hitch will have higher towing and tongue weight capacities. The primary issue with using a Class II accessory in a Class I hitch is that many Class I hitch receivers actually have a built-in tab/stopper inside the receiver that physically prevent a Class II accessory from fitting. Trailer hitch manufacturers do this in order to keep a Class I hitch from being overloaded, since a Class II accessory will typically have a higher weight rating than what a Class I receiver is designed to support.

We have a large selection of hitch-mounted accessories that are compatible with Class I trailer hitches. If you can let me know what type of product or adapter you are needing, I will be happy to make a recommendation.
