Buy Now: QuietRide Tightening Hitch Pin and Lock
This locking hitch pin from Softride is a great accessory for bike racks, cargo racks, and towing ball mounts. The keyed lock keeps your gear locked to your vehicle. The black plastic item with a threaded nut inside is an anti-rattle device. It goes inside your ball mount or drawbar. The 5/8" pin shank goes through the ball mount and threads into the anti-rattle nut, pulling it tight to the side of the receiver. This tightening action eliminates slack in your hitch connections, which in turn eliminates rattling and clanking while you are driving.
