Hitch locks help protect your cargo by fusing your trailer hitch and receiver together, preventing thieves from making off with your stuff.

It's race day at your local speedway, and you've got your motorcycle ready for some high-octane knee-dragging. Your pickup truck is towing a trailer with the motorcycle secured on top. Once you arrive at the track, you go off for a while to visit with some friends. When you come back, your truck is there, but the trailer - and your motorcycle - are gone.

Nothing ruins a good weekend of racing (or a good weekend in general) like having your entire rig stolen from under your nose, but it can happen. Fortunately, there is towing equipment available to prevent incidents like that from happening.

Hitch locks are designed to stop thieves from stealing your trailer. A hitch lock keeps your trailer hitch and the receiver together until you unlock it, often with a key. These locks prevent anyone from lifting the receiver, and they won't be able to un-hitch the trailer unless the lock is off.

In this next section, we'll discuss the many different types of trailer hitch locks, and which of these hitch accessories are right for you.
