Video Transcript for Andersen Hitch Locks - Standard Pin Lock - AM3493 Review

Today we're going to be taking a look at the Anderson trailer hitch lock and adjustment pin lock set. It's going to include two anti-theft keyed locks. These are going to keep your adjustable ball mount securely attached to your towed vehicle. Now, on the internal portions of the actual lock that goes on the end of the pins, inside we're going to have a triple ball bearing mechanism. This is going to ensure a solid, secure attachment. Another new thing I want to show you is it's got like a snap-lock design, so you'll actually be able to hear it lock into place.

Push down, and it clicks into position, letting you know that it's securely locked, so you don't have to deal with any false locks. Now, when it comes to the construction of each one, they're pretty much identical. They're just different sizes. They're going to contain stainless steel, aluminum, zinc alloy, and steel construction. Everything on the unit's going to be rust-resistant as well as corrosion resistant. On the exposed steel parts, they use a nice coating that's specifically designed to help resist rust and corrosion.

This product's going to come with two keys. These keys are keyed alike so either key will work on either pin and lock set. These are going to be designed for easy and easy heavy-duty adjustable ball mount systems, part numbers AM3290, 3295, 3296, 3297, and 3298. Those systems are sold separately. Taking a look at each one individually, we're going to start here with the receiver lock. This is designed for two-inch by two-inch hitches.

It'll also fit over-sized two-inch by two-inch and two and a half inch by two and a half trailer hitch receivers. This is going to go through the pin holes of your hitch and the ball mount, and that's going to lock it to your vehicle. The usable pin length we have, measuring from this portion here to this portion here, that's going to give us a usable length of about three and five-eighths of an inch. The diameter of the receiver lock, that's going to measure five-eighths of an inch, and then the overall length, measuring from edge to edge, that's going to give us a measurement of about seven and one-eighth of an inch. Now we'll take a look at the adjustment locking pin. This is going to give us a diameter of three-quarters of an inch.

The usable pin length, that's going to give us a measurement of about one and seven-eighths of an inch, and then the overall length, that's going to give us a measurement of about five and three-eighths of an inch. Really nice design. Again, this one's going to lock the mount to the receiver tube of the hitch, and this one's going to lock the actual ball platform in position on the mount. These are going to have a capacity of 30,000 pounds, and again, they're built for strength and durability. They're going to last a long time. They're almost completely rust and corrosion resistant. I think they give it a 99.99% rating at resistance toward rust and corrosion, so that's about as high as you can get, and as close to you can get to being 100% rust and corrosion-proof. That's going to do it for our review of the Anderson trailer hitch lock and adjustment pin lock set.

Just installed, but was as described. 414829

Still One of the Best. Also might add those desiring a 5th Wheel Anderson Hands Down THE VERY BEST. Used about a year after using all the rest, Nothing Compares

They work fine but after just one year, (not counting the winter I took the off the vehicle) they are already rusting and corroded. I hoping they will last one more year. 524096

- AM3493

Perfect! Fits the 2013 factory Tundra hitch PERFECTLY. Same key system, locks ball mount to sleeve, sleeve to receiver. I had been looking for this type of hitch/key lock for some time and was very happy with all the help E-Trailer and Jena provided in getting me one of their newest items of their inventory. I'll keeping back. 176420

- AM3493

Strong, durable and easy to lock/unlock. 521902

- AM3493

The product is good, exactly as expected. etrailer ordering and processing service is also very good ... thank you. I wish they could avoid CA sales tax like last time I ordered. Shipping was a bit slow ... UPS takes their time. 677057

- AM3493

Very well made product. Arrived very quickly. Had to send this one back because I ordered the wrong model, but I'm sure the correct one will be equally nice that is still en-route. 414426

- AM3493

also bought these for my work trucks, work awesome 782003

First of all, etrailer has been my supplier of truck and trailer parts for years and a pleasurer to do business with, great service... The hitch locks where as advertised, the hitch was perfect! 750210

- AM3493

Great product with fast shipping. 728213

- AM3493

Works well, should just be included with hitch. This pins work great for anti-theft, keys fit well and stay with the lock until back in place. Rubber caps are a bit loose, so I wouldn't bet on them sticking around forever. 711603

- AM3493

The nice thing about this lock is the longer bar which was a better fit on my Toyota Sequoia hitch. 636120

Works great, easy to use on adjustable hitch 493071

- AM3493

Cannot get unlocked anymore. So corroded it doesn’t operate 470939

- AM3493

I really like these locks. They have held up to quite a bit of abuse, especially considering one is used in a front hitch and sees all kinds of weather and road debris. The only issue I've had is the locks themselves get a little stiff (like any lock would), so a quick squirt of lubricant every now and then keeps them working smooth. 448356

- AM3493

I ordered a pin lock set and a part was missing. Called there 800 number and they email me a shipping label to return the bad part. They shipped out my new one the same day. Very good service. 412159

- AM3493

These are great. They are well made and have been working well. 405044

I love these locks. Always easy to lock and unlock. I like the fact you can't remove the key until it's properly locked. 394252

The latch feature is much better than other brands 391325

  • Recommended Hitch Lock for 3 Inch Factory Trailer Hitch on Ford Truck
    For the factory 3 inch trailer hitch on your 2018 Ford truck I recommend taking a look at the Draw-Tite Trailer HItch Lock # BD580412. This is the longest hitch lock we have available and it is designed to fit 3 inch hitches like what you have. It features a usable length of 3-7/8 inches. I do recommend measuring the outside width of your hitch receiver just to make sure this will be long enough. This lock features a heavy duty steel construction and a nickel finish to help resist corrosion....

    For a standard hitch pin lock made in the USA we have the Deadbolt part # BD580405 that will work great.

  • Will Andersen Trailer Hitch Lock Set AM3493 Fit Hitch of 2017 Ram 2500
    Yes, the Andersen Trailer Hitch Lock and Adjustment Pin Lock Set # AM3493 that you referenced would work just fine in the hitch of a 2017 Ram 2500. It includes a standard diameter 5/8 inch hitch pin with a very wide span of 3-5/16 inch. So if you have a 2 inch or 2-1/2 inch hitch this would work well with it.

  • Can the Andersen Trailer Hitch and Adjustment Pin Lock Set Be Used on a Weight Distribution System
    According to Andersen, they do not recommend using any pins to attach the ball housing to the weight distribution system's shank which includes the Andersen Trailer Hitch Lock and Adjustment Pin Lock Set part # AM3493. They recommend that you use the nuts and bolts included with the kit. You could use the longer pin on the hitch pin hole but not the shorter pin on the adjustment hole.

  • Hitch Pin Lock with 5/8 inch Diameter and 3-1/2 inch Span
    We have a pin lock that's sold individually that has the 3-1/2 inch span you need with the same diameter as the # AM3493 but the included lock of this is 5/8 inch which is the standard hitch pin size. So for that we have the # WS05 which has a 3-1/2 inch span and a 5/8 inch diameter. For the larger hitch sizes like 2 inch and up (including 3 inch) the diameter hitch pin used is 5/8 inch.

    The EcoHitch Invisi Trailer Hitch Receiver - Custom Fit - Class III - 2" # 306-X7257 is a great fit for your 2017 Subaru WRX STI Limited. It is rated for towing up to 3,500 lbs but Subaru does not recommend towing with your vehicle according to the owner's manual. Many customers have chosen to tow small trailers anyway and we have not heard of issues but it would be at your own risk. If you decide to tow your 16 foot jon boat with this vehicle, you will need the Curt T-Connector Vehicle...

  • Is There a Locking Ball Mount Rated for Over 10,000 lbs?
    The only B&W Tow & Stow ball mounts we offer that have a towing capacity over 10,000 lbs and fit in a 2" hitch use a pintle hook, like # BWTS10055. There are adjustable ball mounts from other manufacturers that fit in a 2" hitch and can give you the capacity you need. The MaxxTow Adjustable 2-Ball Mount # MT70380 is one of those options as it has a 12,000 lb capacity with the 2-5/16" ball and offers a maximum rise of 7-7/8" or maximum drop of 6-1/4".

The Tow Ready J-Pin Stabilization Pin and Barrel Lockset for 2" Trailer Hitches part # 63201 is made of steel with a brushed finish.

  • Locking Pin Recommendation for the EZ Hitch Adjustable, Steel Ball Mount AM3296
    As long as the pin diameter matches up on your Adjustable Ball Mount part # AM3296 with the part # C23556 the locks being a bit too long would not matter. Normally we would recommend the part # AM3493, but if the Curt fits it would work as well.
