"It’s one of the beefiest trailer locks I’ve ever seen. Everything is made of thick solide steel and I think it’s so much stronger than the coupler it secures that making anything beefier would definitely be gilding the lily"

This thing is a beast. Its going to take a lot of work to get it off the coupler without a key. AMPLOCK is the best!

One of the best king pin locks that I have used. Very well constructed and extremely heavy duty.

This is the best trailer hitch lock for your money! Our 2022 boat & trailer sit in the driveway at our lakehouse, 1 hour from our house, so I need something secure. I use a combination of 5/16" chain & locks (thick SOB's), a locking pin on the hitch AND this bad by hitch lock. No one has touched the trailer

Spend the money once and you'll know why you bought it. I can bet my left nut, my trailer will NEVER be stolen using this hitch lock. I have one for my 5th wheel and it is equally as HD!

This lock fits the square noes boat trailers perfect! Lock is SUPER HEAVY and is a great design. We'll worth the money.

My custom Airstream trailer has been parked in the South Bronx behind some abandoned buildings for a month while I was in jail with this lock on and so far, no problem. Seriously, I wouldn't recommend that, but this lock does provide a good layer of security that other jokes of trailer locks don't. I recommend it. But I'd also recommend other layers like securing the wheels with lug nut locks and using a 9/16" link hardened security chain through the wheels and the suspension. And parking it in an inherently safe location. And using this lock.

This lock feels like a tank, super solid and durable built to last, don’t hesitate to purchase this

This lock is built like a tank. The price is high but like they say you get what you pay for, so happy to make this investment if it will deter theft of my camper. It was easy to put on the trailer so can’t complain.

No lock is perfect protection, but this is the best I found. You either need to be a professional lock picker working upside down, or remove the coupler from the trailer frame. The pin that secures the cast iron cover to the lock in the ball is adjustable so you can get a tight fit. The pin is only adjustable from the inside so it can't be tampered with. Vanessa at the factory provides lightning responses to any question. Expensive, but the very best thing I could find anywhere. Great design by AMPLock!

Having read the reviews of others identifying how easy it was to cut off some of the other locks and because I have a very expensive dump trailer I went with what appears to be the best. It is shocking the weight and heft of this lock. I am not worried that my trailer will be disappearing in the middle of the night as has been happening lately. I highly recommend this lock.

I love these locks and now own three of them for my trailers. With AMP Locks, I feel like I can walk away from my trailer in most scenarios and it will be there when I get back.

I immediately noticed how by the heft alone this seems like a quality product that was ruggedly built. Installation was super easy and locked up tightly with no play. I’m hoping the downward and gel of the key keep water from entering and freezing up in the winter.

This lock work very well. I have been using it for 2 years now and they have never fail me. The build quality is good for a casting piece and the core use a nice disk retainer system with anti-drill feature. They work any penny I spend on them.

Solid design with great powder coat. Well worth the money.

This lock is certainly the sturdiest lock in the RV park from those I have seen and used on other 5th Wheeler's. Some reviews have said it was heavy and that is precisely why I purchased this lock over the competitors. I wanted something heavy and sturdy and this is it. Just from the shear size of this lock, I bet it would be easier for the potential thief to unbolt the King Pin Hitch and simply put on a new hitch rather than to try to cut the lock off. Another reviewer said, the lock will keep the honest people honest. I fully agree with that statement. This lock won't be easily defeated.

Exceptional quality, extremely heavy duty, I definitely recommend this, the saying “you get what you pay for” DEFINITELY applies here. Quality products ain’t cheap and cheap products ain’t good!! Definitely puts my mind at ease knowing I got a trailer lock that the Devil him self would have a hell of a time even putting a damn scratch on this lock
