Video Transcript for Tow Ready Gorilla Guard Trailer Coupler Lock Review

Today we're going to be taking a look at the Tow Ready Grill and Guard Coupler Lock. We've got two sizes available. The 2" is part number 63228; the 2-5/16" is part number 63227. These trailer coupler locks are great for securing your unattended trailer, preventing anybody from being able to hook up to them. They offer a gorilla guard design, which as you can see is a nice, heavy-duty lip, with structural supports all the way around our lock to prevent any kind of tampering. It has a single action, cylinder style key. Push in, a quarter turn out.

Key is removable. To attach it to your trailer we simply bring it onto our coupler, push up on the lock. As you can see that's all there is to it. Our trailer is secure, we can leave it for a while and don't have to worry about anybody hooking up to it and it getting taken from us. Now that we've gone over the details and you've seen how it works, that will complete today's look at the Tow Ready Gorilla Guard Coupler Locks, part number 63228 in 2" and part number 63227 in 2-5/16". .

Average Customer Rating:  4.8 out of 5 stars   (83 Customer Reviews)


Works well. Small hassle to get underneath to lock or unlock. Would recommend to others.

Still works well.
Jakester - 11/16/2022


Very impressive hitch lock. I put it on my log splitter and I feel like it is safe now. I had one stollen, but I don’t think they will get this one.

I now have one on my trailer and pull behind smokergrill as well as my log splitter. So the locks have worked well. Great product.
David - 11/19/2018


Excellent product, excellent customer service. Highly recommend.


The coupler lock works as advertised and the etrailer measurements were perfect. The tie down brackets were also easy to install and work well for holding down my ATV and UTV. The spare tire carrier, wheel and cover all came from etrailer. They fit perfectly.


Great lock


Feels solid. The lock is beefy. It does not feel cheap. It fit my haulmark 6x10 perfectly.


Trailer hitch lock still working great 1 year later. An advantage of this cylinder lock system is that once you take it off the hitch, you can take the key out and when ready to lock your hitch again, just slide it on and push the lock up into the ball receptacle - job done.


The Gorilla (trailer hitch) Guard works better then any other guard I've used...

Excellent protection...easy on and easy off...key works great.

Still works well

I have 4 of these locks on my trailers for the last 20 plus years and have never had any issues whatsoever. Best lock for A frame type couplers.


Seems very well built. Now I have peace of mind that no one will steal my boat at a storage facility.


Great transaction , great product , purchased trailer tongue lock that comes with two keys for $29.95.(FAIR PRICE) . I could not order product with additional keys, I had to wait for the lock and then order additional keys. TWO ADDITIONAL KEYS COST MORE THAN THE LOCK , $37.84 for two keys. Just doesn't seem right!!!


I purchase 3 trailer locks from etrailer, Heidi took care of the order and everything was shipped out promptly and handled correctly. Yes I plan to order more from etrailer in the future. Very satisfied, Jack


I purchased my trailer used, but in excellentshape and the seller had the Gorilla Guard Trailer Coupler lock on the unit. He would not let the lock go with the trailer and spoke so highly of it, I purchased my own. I could not be more pleased with the product or Their service was speedy and flawless and the price of this item ranged widely from several vendors and their price was the best by far.


This trailer coupler lock fits my trailer well.
Shipping was quick. I am satisified.
Thank you, etrailer.


Works great! Easy to instal and remove.


Havn't had the product long enough for a complete evaluation but it is exactly as I expected it to be and fits my 10x6' trailer that I haul my trike and other things on as expected and as decribed. I use it along with a hasp lock and plan to take vacation with it soon.


So far a great hitch lock and extremely fast delivery, will buy from y’all again!!!


Great product and this is my second purchase for new trailer. Fast shipping and I can always seem to find what I need here. Great customer service too, if I have questions.


Installed easy enough, looks nice. Hopefully the Mission trailer will remain in the church parking lot with this added protection. Glen, Smithfield


Have been looking for a drop hitch and vehicle/trailer flucuate between 3 1/4" to 4 1/2" drop depending upon load(s). Researched many and BW seemed to be best/recommended choice. Haven't used yet, but very solid construction.


E Trailer is the best of the best for there service.Christy who helped me place my order was helpful and shipping follow up was most helpful. I would buy from E Trailer again!


Fit right onto a standard 2" ball coupler. Very easy to lock onto trailer. Should deter most thieves effectively.


Nice addition to a trailer that is left out. Still works well.


Its very quick to put on and seems fairly stout, I feel better knowing its on my trailer when I leave it unattended.

  • Selecting a Secure Coupler Lock
    The purpose of any lock is to keep honest people honest. If the potential thief is determined, any lock can be eventually defeated. The key is to make defeating the lock as difficult, time consuming and noisy as possible. The design of Gorilla Guard Coupler Lock part # 63228 helps make defeating it more difficult than other locks because the actual locking pin is inaccessible when the lock is in place. The fact that this lock uses a barrel style key instead of a flat key also makes the...

  • Is There A Replacement Barrel And Key For A 2 Inch Gorilla Coupler Lock?
    We don't have any replacement parts available for the Gorilla Guard Coupler locks. You would need to replace the entire coupler lock with # 63228 to get the new barrel and key. I've attached a video of this product for you.

  • Coupler Lock Recommendation for a 2015 Jayco White Hawk 27DSRL
    If the coupler on your 2015 Jayco White Hawk 27DSRL has a lip that does not exceed 3-13/16 inches and is not thicker than 5/16 inches the Gorilla Guard Coupler Lock part # 63228 that you referenced would work well for you. Check out the review video I attached for more info.

  • Does Every Gorilla Guard Coupler Lock Come with Same Key
    Each Trailer Coupler Lock part # 63228 that you referenced comes with a unique key. They would not all come with the same key so you wouldn't have to worry about someone else with the same lock being able to unlock your trailer.

  • Which Coupler Lock Would Best Fit my 2-5/16 Inch Coupler with a 3-3/4 Inch Wide Lip
    The Gorilla Guard for 2 inch couplers, part # 63228, would be so snug it would not be easy to get on and off, not to mention the curved portion up front may not fit the larger 2-5/16 coupler nose. The Gorilla Guard for 2-5/16 inch couplers, part # 63227, would be a better fit, though it will accept couplers of a greater width than yours, it should not be loose enough that it would not be able to prevent theft. You could also look into a different style of lock. I have included a link...

  • What Materials are the Gorilla Guard Coupler Locks Made Of
    I called the manufacturer regarding the construction of the the Gorilla Guard Locks, part # 63228 and part # 63227. The main portion is a black-painted SAE-903 spec. steel casting. I pulled the lock from our warehouse to take a close look. The lock and pin are cast as well and appear to have a zinc coating. The keys are brass.

  • Choosing the Correct Size Trailer Coupler Lock
    The coupler size should match the ball size it is coupling to. If you have a ball with a 2 inch diameter then you would need a 2 inch coupler lock. If the ball is 2-5/16 inches in diameter you would need a 2-5/16 inch coupler lock. For 2 inch we have the Trailer Coupler Lock - Gorilla Guard # 63228 that is featured in the video you cited. For 2-5/16 inch we have the Trailer Coupler Lock - Gorilla Guard # 63227.

  • Coupler Lock for 2016 Jayco Jay Flight 27BHSW
    If your 2016 Jayco Jay Flight has a coupler for a 2-5/16 inch hitch ball, you will likely want to use the coupler lock # 63227. If the coupler on your trailer is for a 2 inch hitch ball, check out lock # 63228. These locks fit around the lip running along the bottom of the coupler. If your coupler does not have this lip, feel free to send me a photo of the coupler whenever you get the chance and I will be glad to make a more specific recommendation.

    We do offer a version of the Gorilla Guard for 2-5/16-inch couplers, part # 63227. Part # 63228 that you referenced fits 2-inch ball couplers.

  • Gorilla Guard Coupler Lock Recommendation for 2 inch and 2-5/16 inch Ball Coupler
    2-1/8 inch is not a standard hitch ball size. Because of that none of the locks we offer like the part # 63228 are going to fit. You might measure again to see if you happen to have a 2-5/16 inch ball which would mean you would need the # 63227 instead. If you do happen to have a 2 inch ball the part # 63228 would be a fit.

  • 2 Inch Trailer Coupler Locks that Can be Keyed Alike for a Fleet of Trailers
    We have several coupler locks for 2 inch couplers that can be ordered keyed alike but the Gorilla Guard # 63228 is not one of them. I have included a link for you to the ones that can be ordered keyed alike. A lock such as # e98895 is similar to the Gorilla Guard. You would just select the keyed alike option, near the add to cart button on the product page, select the quantity and they will all be keyed the same.

  • Coupler Lock Comparison for Securing a Travel Trailer
    Any type of lock you put on your trailer will be a theft deterrent. I recommend using the Fastway Universal Coupler Lock, part # DT25013KA, because it can mount on 1-7/8, 2 and 2-5/16 inch couplers and it fits on a wide variety of coupler types. The Diversi-Tech lock will be harder and noisier to break off than the Master Lock coupler lock which is a better deterrent for thieves. Wheel locks are also a secure option, but can be tedious to apply and still gives thieves a chance to hook...

  • Coupler Lock Recommendations for a Titan Multi-Fit Coupler
    You will need to take a couple measurements on your Titan coupler to be sure it will fit, but I would recommend you get a Tow Ready Gorilla Guard # 63228. This lock will slip on the front of your coupler and should work well as a theft deterrent. The width of your coupler (including the lip) should not exceed 3-13/16 inches and the lip should not be thicker than 5/16 of an inch. Another option you have would be the Master Lock Universal Trailer Coupler Lock # 379DAT, this will work similar...
