Blue Ox BX88212 5/8" x 4" Class III-IV Receiver Lock Kit

It works and it fit the 3 inch receiver on my 17 Ford F350. I've back off some stars because it has only been on a few months and is already starting to rust.

This works fine but is mis labeled online. It is well over 4" long (clear area) and will stick out about 2.5 inches to the side on a class 3 hitch (2") The package does not even claim it works with class 3, although the listing says it does. It will work, but I really wish I had bought one that wasn't way too long.

Beefy, but to long for a 2019 Ford Super Duty hitch.

I like the longer length.

very good

Great. Only complaint is that I can't get another key at a locksmith - just slightly different diameter than what he has.

Plenty long enough for 2.5" receiver

The first time I received it there was 1 lock. The next shipment came with 2. I called amozon and they pulled the ad because it was a 4 lock set
