Extensive Testing
InfiniteRule products undergo extensive third-party testing to determine shear strength. The shear strength is determined by placing the locking pin in a stress position and subjecting it to increasing force until a required proof load (maximum force received without deformity) is met or the pin fails. This lock has a shear strength of 32,000 lbs.

Hello everybody, this is Jeff at etrailer. Today we'd take a look at the Infinite Rule, three quarter inch diameter stainless steel hitch locks. And this is for the fast wave flash HD adjustable ball mounts and the Gen Y 32,000 pound mega duty adjustable ball mounts. If you notice, this kit will include three locks. Now these are a durable stainless steel lock. They'll replace the standard pins that's on that fastway flash HD adjustable ball mount, and also the Gen Y 32,000 pound mega duty adjustable ball mounts.
Just to give you an idea what we're talking about, I'm gonna pop up an insert that's an example of one of the gen Y ball mounts that these locks will work on. The three locks are interchangeable, they are all keyed alike. You can use these locks to secure the ball mount and the accessories to the adjustable ball mount platform. One thing that I do wanna mention, these locks will not, do not fit the vehicle's hitch receiver. So if you wanna lock the ball mount to your hitch receiver, that will require a different lock.
Now the shear strength on these locks, it's 32,000 pounds. The diameter, again, is three quarters of an inch. The overall dimension, the length one end to the other is six and a half inches. The inside length or usable length, which is from here to here, is three and seven eighths inches. These are a nice durable stainless steel construction.
They'll prevent rusting. They do go through rigorous testing to ensure the hitch lock can handle extreme towing and off-road activity. If you notice I've taken this lock off, this one right in here, it has this nice O-ring which will protect the internal components from dirt and grime. So when you go and install this, you'll slide this through the hole and then you'll put this on the end, twist it until you hear it click, and then take one of the keys, put your key in, and then just twist it like you're tightening down a bolt. And after a few turns it'll tighten up.
And once you get it snug, what you'll do is turn the key, there's four different marks on there. Just turn the key to one of the marks like that and then you'll be able to slide the key out. You have to turn the lock to one of those marks to pull the key out and then put the cap back on there. And now it's all locked ready to go, simple as that. The weather resistant tethered dust cap is nice 'cause it'll keep water debris out of the keyway. Now it does come with three keys and as we mentioned, the lock coolers are keyed alike, so the one key would work on all three. These parts are made in the USA. Now if you do have any other additional questions regarding this part or any other item we carry, please feel free to reach out to us so that we can help you get all of your questions answered for you. But that is gonna do it for a look at the Infinite rule three quarter inch diameter stainless steel hitch locks for the fastway flash HD and the Gen Y 32,000 pound mega duty adjustable ball mounts.

Order was handled smoothly and the tracking was excellent! Will certainly order again when needed.
Perfect fit for the 4th Gen Tacoma.
I leave the lock on my hitch 24/7/365 so it is always exposed to the weather. Truck spent a couple of months parked in seashore environment. Removed the lock a few weeks ago and had no problems. The plastic cover over the key slot seems to have protected things well. Very satisfied with the locks, couldn't ask for anything more.
Great product and perfect length. Not your average hitch lock...very well designed.
Beautiful machined stainless steel- have it on the truck but haven't pulled with it yet.
One thing a little odd and time consuming is that the only way I could unlock it was to turn the key counter clockwise and unscrew it- didn't expect that and it is awkward.
Time will tell.
Receiving this lock I was disappointed. The end opposite of the key lock is smaller than the in photo on your website. To be specific, its only 3/4”, which is only an 1/8” larger than the shaft itself. (See photo) Over time hitch receivers get sloppy from use and can enlarge the 5/8” lock pin hole. In short, the end should be at least 7/8 to 1” in size to allow for hole slop. Another thing is it’s difficult to hold the end while turning the key. The quality seems good and I like that it’s made in the U.S.A., made of stainless steel, and its 3 5/8” length. However, due to the issues I mentioned above, I will be returning it. Don’t know what the manufacturer was thinking here and unsafe in my opinion.
Yeah, I like the way it’s made stainless steel twist lock key release at 12 3,6 and 9 positive, alignment with four corners, male and female, and a readily available O-ring in case the other one breaks. I plan on putting anti-seas in the threaded portion of the lock in a waterproof grease everywhere else. Ordered through online and was on my doorstep before I knew it. In other words very well made thank you.
Have used the 2" version in the past. Both work great. Tamper proof for sure. Of course hasn't rusted (stainless). Another etrailer quality part. Worth the investment IMO.
Independent strength tested
Add this to your Blaylock EZ Lock Gooseneck Coupler Lock - Bulldog/Stallion/Superior/T.E.M. Gooseneck Couplers and know you've got some of the best protection available for your trailer.
Great product.
We live a few miles away, could have picked it up the very same day.
Instead we paid $5 for mail delivery, it took 4 days for it to be delivered a few miles. Please consider a will-call desk.
As advertised and fast shipping! Thank s!!!
The lock is super easy to use. I like that it fits tightly to the receiver which should deter someone from simply breaking it off.
It is a very good and strong hitch. I haul many different trailers and loads and it handles them all flawlessly. Make sure you use the grease (that comes with it) on the pins to be able to easily move the hitch when needed.
So happy with this lock. Been looking everywhere for 1. Fits my gooseneck perfectly and I feel safer now that my new air ride shock absorber hitch is now locked on. Thank you. Fast ship as usual , great service
So far, this looks to be much more secure than any other hitch lock on the market. My last B&W hitch was stolen from me at an airport parking lot. The thieves managed to use a chisel to just knock the locking mechanism off. Ultimate Rule's design where it screws into itself will prevent this method of theft, and the close tolerance design prevents most any method of cutting that I can foresee. Great design, fingers crossed!
Product is what I expected made in the USA best receiver for your money
Christmas gift for my son. Lock fit the trailer hitch perfect. Shipping was prompt. Tracking was easy to follow. Happy with the entire transaction process.
I returned it. I wanted this one as a locking pin on my adjustable hitch. So this didn't go into my hitch receiver but on the adjustable part of my adjustable hitch. The flare/flange on the non-lock side of the pin was no were near large enough to prevent the pin from just sliding straight through. For reference, I have a fastway adjustable hitch that I bought from etrailer.
The hitch locking pin is well built and I would buy again, but not again from etrailer. That is saying a lot, because I have been buying from etriler for more than 15 years. Their customer service and return policy now stinks. I accidentally ordered the wrong length of pin, which is my mistake. Within 5 minutes I called their customer service and hit an automated service telling me there was an almost 20 minute wait. The item was still pending being sent. I immediately sent an email explaining what happened and asking to exchange the item for the correct size. I did not get response for 5 days, the day the item arrived. Alternatively, I received a email the same day about a different item. The email was apologetic but stated I would have to pay for postage both ways, which was more than half the price of the item I purchased. I could have bought the same item from [online vendor] for slightly less with free returns. I guess I know where I will be looking in the future. Customer service is king in my opinion. I will pay more if I receive superior customer service.
its a hitch lock, so not much to say, but it works great and nice to keep my B&W tow and stow attached all the time without much concern of it disappearing.
I bought these items are they are supposed to be very string
Will not fit 2 1/2” hitch
