Most Popular Universal Anti-Rattle Lock for Car

Clearance around the Tesla Model Y hitch receiver is tight but this anti-rattle hitch lock fit perfectly, even after torquing it to spec. The lock mechanism on the left comes very close to the 7-pin connector but it doesn’t touch and the lock rotates freely around the pin. Product appears to be of high quality.

This is a brilliant designed anti-rattle hitch receiver. Easy to install, it both locks your hitch and prevents any shaking from bumps and hard turns. I use it primarily with the Reesa Cargo Carrier, and the carrier is completely locked into the hitch. Also kudos on the great video showing how it works and install instructions. Highly recommended.

I use this lock on the my Brophy 7 inch hitch adapter that is on my bike rack. Works! Easy on and off. No rattles or play after a year of use in rain, snow and sunshine cause it is so rugged. And I don't see how you could cut it off. You would need a torch. So it gives me security peace of mind on the road and overnight in hotel parking lots.

Quality construction. The bolt is stainless and much thicker than other entitle pins of this design. The holder for the nut was a little large for my accessory but it’s plastic so it was easy enough to trim with tin snips and a sanding block. Does an excellent job of stopping any rattle or movement of the hitch accessory.

I love the product, unfortunately the threads do not last. This is my second one in just over 2 years and will need a replacement before this biking season is over. Threads are easily damaged by overtightening, but if you don't get it tight enough the bike rack wobbles.

The unit itself seems like it should work well. I've installed it, but haven't loaded up the cargo carrier. As some of the other reviews indicated, the o-ring (to keep water out of the lock from the pin shaft) was broken upon receipt of the product. I was able to find and install a new o-ring on the pin, however the clearance between the tightener nut and the shaft of the pin is so tight that it catches the o-ring and won't allow the nut to pass. I got the smallest o-ring I thought I could get over the shaft and it fit nicely into the slot for the o-ring on the shaft. When trying to remove the tightening nut, it ripped the o-ring, which I suspect is what happens to the OEM o-ring. My solution is now to just put some grease at the end of the shaft to minimize moisture in the lock mechanism. Messy but the only viable option, since the basic functional design seems solid. Just a poor "detail" design that doesn't affect the basic functionality.

Works with Yakima EXO and Lexus LX600 if you replace the Yakima anti rattle nut. Voids Yakima warranty, but anti rattle nut can be restored. Ucaveat, you may need to use only one of the two washers, I chose the lock washer

Too soon to see if has any durability. It did stop the rattle.
