Most Popular Built-In Locks for 2021 GMC Yukon

Very strong, easy to install and very secure. Yes a bit pricey, but well worth the money. I did notice there was what I thought was an unusual amount of play in the receiver. I called etrailer and Marcia was so very helpful and very concerned that I may have received the wrong product. She even called the manufacturer and found out what the changes that were made by the manufacturer which made the pictures incorrect. My hat is off to Marcia and all the folks at etrailer

ball mount fits loosely in the receiver so that the pins that extend out from the ball mount shaft through the holes in the receiver don't extend out far enough, for my liking. This is because since the ball mount shaft has so much play, it will shift to one side. Then, the pin on the other side does not extend all the way out of the hole so that it is not flush. True, i am being paranoid. However, i imagine a case like a crash where enough force could pull the shaft out from the not fully extended pin side to release the trailer to wreak more damage. I would just feel more secure if the pins went out further through the receiver or the shaft was not so loose. Otherwise, i really like the product a lot... enough to give it four stars... :o)
