Bought for a 2021 ford F-350. This thing is heavy but kinda what you want when you're hauling a horse trailer. Slides in and out of the receiver hitch with ease. Bought this because tractor trailer, horse trailer and boat trailer are all different heights. 6\" too high. 8\" too low. This got us at the 7\" we needed. There are 4 keys, and the locks are keyed alike. Thats kinda overkill. Only complaint is the #5 hitch pin clip are not up to par. They are thin and cheap. We had some around the farm, so it wasn't a big deal to put a heavier duty one on the pin. Well worth the money for multiple trailers.
