Our Picks for the Best Trailer Hitch Locks
There are many cheap trailer locks and hitch coupler locks, but they are easily broken, leaving your trailer ripe for the taking.
Cheap locks can be broken off with a pair of bolt cutters or a wrench, making them relatively useless in protecting your property.
For this reason we recommend one of the following five high quality and durable security locks for your trailer hitch.
1) Reese Towpower (72783) Universal Coupler Lock
This hitch lock by Rease is built strong and is very durable.
It comes with a heavy duty locking mechanism that isn't going to be easily broken or messed with.
It is made of quality steel and is painted and corrosion resistant.
I really like how it comes in a universal fit size, meaning it is going to work for all common hitch sizes as it is adjustable.
Hitches sized 1 7/8, 2 inches, and 2 5/16 will all fit.
The Rease Towpower Coupler Lock is four inches wide and has a three and a quarter inch coupler head.
It also comes in a few different colors. I personally like the yellow one pictured above.
2) Tow Ready (63228) Gorilla Guard Coupler Lock
The Gorilla Guard trailer lock has a very different design than the Reese. But don't let that fool you, this one is a beast.
Designed to simply be slid over your coupler, it is made to withstand being hit with a hammer without breaking and coming off.
Thieves are not going to get this one off your trailer.
The Tow Ready will fit a 2 inch ball and the company believes in it so much that they include a one year warranty (but you likely won't need to use it).
This hitch lock is easily one of the best out there right now, strong, great design, and easy to use.
3) Master Lock 377KA Trailer Coupler Lock
Master Lock is well known for their everyday locks, but they also make a darn good trailer lock too.
The MasterLock 377ka is an excellent choice that comes in a couple sizes, 1 7/8 in and a 2 5/16 in model. Both are chrome and come with a couple keys (which I find incredibly handy).
This hitch and coupler lock has a much more aerodynamic profile, they say makes it more resistant to being hit with a hammer or someone attempting to pry it off your trailer.
Just like the previous models, this one is easy to install. Once fit on it will stay snug and resistant to would be lock pickers.
4) Proven Industries 2516 Trailer Lock (Ultimate Hitch Lock)
The last two entries on our list are for those who demand the best trailer and hitch locks available.
Whichever of these two you choose, you can be sure to sleep easy at night knowing your trailers are safe and where you left them.
The Proven Industries 2516 is guaranteed bolt cutter proof.
This bad boy is engineered so precisely that the company has backed it up with a lifetime guarantee. This is one of the best two trailer locks you will find.
Made from super strong 1/4 in steel and surrounded with a thick armor guard, this hitch lock will stay put once locked on.
It also comes in every popular size, meaning you can get one for all of your trailers and keep them secure.
The Proven Industries 2516 comes with a healthy price tag, but is well worth it. Hands down one of the best locks out there.
