Review on CZC AUTO Heavy Duty Trailer Hitch Receiver Lock Pin, 5/8 Inch Dia, Ultra Long 4 Inch Black Pin for Class III IV Hitches, Ideal for Hitch Bike Rack Tray Ball Tow Rope, Compatible with Trailer Truck Car Boat by Cris Walton

Everything works great so far BUT I only keep the clutch boot I bought. I haven't towed anything yet. I followed the advice of some other users and oiled the lock. I sprayed the lock area with silicone spray and opened and closed 50 times, so far everything is fine. The pin is very long and I was tempted to buy some shims to make it fit better. However, I don't hear any noise from behind while driving. There's also no knocking or moving of the clutch cover. I like the ability to just insert a pin into the top of the lock without leaving the key in it. Very convenient. Overall I like this clutch so far. Just recommend this for something as simple as securing a hitch cover.
