Note: This lock will not work with some factory 2" trailer hitches that have an outside width wider than 2-1/2".
The unique ball-bearing locking system on this Lifelong hitch lock is supremely easy to use. When you pop the deadbolt onto the end of the pin, the integrated ball bearings engage the lock automatically. Grease the ball-bearings periodically to ensure smooth operation.
This ball-bearing system also ensures that the structural integrity of the pin is maintained throughout. A typical padlock-style hitch lock has a significant taper at the end of the pin where the lock snaps into place. This taper weakens the pin, making it easier to break or cut. Because the ball bearings are responsible for engaging the lock on this Lifelong lock, no taper is needed. So, the pin diameter is the same along the entire length of the lock. The result is a hitch lock that is strong, durable and highly tamper resistant.

I purchased this item about a year ago and have used it a dozen or so times. The lock will no longer open and deploy… I have ordered another lock pin from etrailer… Hopefully will have better luck with this one. But the bulldog lock has been a disappointment…. I would not recommend or repurchase.
Sierra K - 08/18/2021I purchased this Bulldog pin for my 2015 Yukon with a factory installed hitch. In this application this Bulldog hitch pin fits very well. I selected this pin due to its simple design and the generally compact diameter of the lock cylinder and the pin's beveled head-end. The lock cylinder diameter is import since GM penetrates the nominal 2" ID hitch tube through a steel bulkhead. There is only 7/16" distance between the hitch tube's nominal 5/8" clearance hole edge and the face of the factory bulkhead. Also, the hitch tube is fillet welded to the bulkhead. Thus, both the pin head and the lock cylinder need to have some relief (i.e. the bevel on the pin head-end) in order to clear this external bulkhead weld. Most of the above fitment concerns are overcome by the Bulldog pin's grip length being greater than that listed on the etrailer site (and in their videos as well). Specifically, the grip length is 2-11/16" rather than the listed 2-1/2". See the attached photos. Note that in the first photo the lock cylinder is firmly seated on the ball locking end of the pin. In the photo note that the cylinder is fully engaged and locked, which would not be possible if the cylinder was not fully seated on the pin end. The first photo shows the dial caliper fully closed and properly reading zero. Also note that the GM hitch tube is 2-9/16" square (outside dim.), thus technically a 2-1/2" pin grip length would be inadequate in this application. Since I have a metal turning lathe I was prepared to machine the pin a slight amount in order to make it fit. Thankfully, this was not necessary since the grip length is 3/16" greater than advertised. The pin is Chinese made in "stainless steel". I did test the pin with a magnet and it does appear to be austinitic (high enough in Ni and Cr alloys) since the magnet had no attaction to the pin. I do like that the lock cyklinder has an internal o-ring to help keep out "road splatter". I also gave the lock cylinder a short squit of WD-40. In sum, a well designed rugged product at a fair price.
Used this with my new 180 Hitch 2-ball mount. Easy to use and feels strong & secure.
Excellent product. I purchased two of these locks and although I have never had a problem at any campsite I have ever been to, it is nice to have peace of mind that expensive items are secure. I purchased one to secure the hi-lo hitch and another to secure the actual tow bar itself. Whenever I have to remove or deploy the unit it is very easy to do so. Just press the button to lock it in place or turn the key and pop the lock to remove. Simple, very well made and am very happy with the product.
Guillermo C - 07/20/2020Takes a little fiddling to get the knack for operating this locking pin, but once you get the hang of it, it is no problem.
Richard - 01/22/2021I plan to install this lock on my RV with a 2" hitch. It locks and unlocks easily. I bought this lock for security, after seeing videos of thieves breaking other hitch locks. I believe this lock is so secure that a blowtorch would have to be used to get it off-it can't be pried or sawed off. I'm paranoid about losing keys, so I contacted Bulldog and requested 2 more keys, and they responded the next day and said they would sent 2 extra keys!
I can't recommend this hitch lock. The locking cap has a pin that fits into the end of the pin, pushing two steel balls outward, which prevent the cap from coming off. The locking cap worked fine, but the steel balls in the pin corroded to the point where they would not withdraw back into the pin. After 22 months on the truck I could not remove the locking cap from the hitch lock. Fortunately, I was able to use a pry bar to force the locking cap off and remove the hitch lock. I do occasionally launch my boat in saltwater but the pin would never have been submerged, so I still wouldn't expect the corrosion. FYI, I replaced it with a screw-on type lock and thoroughly greased the threads.
although the hitch lock is stainless it still has corroded and rusted. Besides cosmetic I'm happy with the locking mechanism.
Don't buy this. It worked, less than 2 dozen uses. In between it was stored in the truck and out of the weather and has not been abused. I noticed once or twice that it seemed unlocked when I reached my destination, and thought I hadn't locked it properly. But now after some testing I realized that by simply shaking the lock it pops open!! Talk about NOT secure...
Bought 2 of these sturdy locking hitch pins to secure a drop hitch to my motorhome's receiver tube and the other to secure the ball mount to the drop hitch. They are quite stout and made from high grade stainless steel. No sign of rust on either one after being exposed to FL weather. It would have been better if they used the same key, but that option wasn't available when I purchased them. I find locking/unlocking them to be very finicky. The main issue is the spring-assisted lock cylinder. It pops completely out of its barrel when unlocked, and if you're not careful, the spring shoots off never to be found again. This has happened to both of my locks. In short, they are well-made but suffer from a poor locking design.
This seems like a pretty good lock. It's solidly built and has a double-ball locking mechanism and a disk detainer core (an uncommon lock style in America, and incompatible with regular lockpicks). I think most thieves and locksmiths would have to resort to using an angle grinder to cut the lock off. My one complaint is that the keys are less than inspired, with only one or two cuts. The lock looks like it has 4 disks, which is very simple for this style of lock. If someone knows what they're doing and has the right tools, this probably won't keep them out for long. Again, most people don't have the right tools or knowledge for disk detainer locks, so it's probably fine.
The Bulldog Lifelong Trailer Hitch Lock is extremely well made but the greatest attribute is how easily and securely you can change hitches. The locking mechanism works beautifully unlocking and snapping back together. Although I cannot rate endurance, I am sure it will wear well.
Good quality. Durable ang easy to use as expected.
Had this lock in my truck for almost a year now. Was working great but I lost the rubber cap that covers the key hole and the salt and slop of upstate New York is making it difficult to lock/unlock.
The customer service and the timeliness in which l have received my orders from etrailer.com is second to none. I needed my hitch to arrive on time so I could pick up a nice chunk of Sycamore. A bit of electrical tape on the shaft to eliminate "play" in the receiver, slip in the new lockable SS pin from Bulldog and off we went to pick up my prize! What a great company to do business with!
Easy to use and provides peace of mind for the added security
My first experience with ETrailer and I was very pleased. The hitch lock is a beast and their customer service is excellent.
After about a year of being under the truck, this lock still works. It is getting a little hard to get the lock off but the key still turns good. I will add some lube to it and see if it frees up next time I change hitch size on that truck. Looks like the rubber o-ring or the balls are a little stiff. Still a good lock and this is expected for where this thing lives on the truck...
Bert - 11/27/2018Very satisfied with this Lifelong hitch receiver lock. It was advertised as being of stainless steel construction and is 100% STAINLESS STEEL!!! There were others that I purchased that stated they too were all stainless, but in actuality they weren't and rusted in a very short period of time. Once again, I'm very satisfied with this product that I purchased from etrailer. THANK YOU!
Anthony - 08/30/2014Seems to be a high quality product, hard to tell unless you try to cut one off. Etrailer is a great supplier to us all, they know what they are doing and also what they are selling. Usually fast and efficient, not around Christmas so much, USPS swamped and all are the same I am sure! Of course I will buy from etrailer again, have for some time now.
Works exactly as expected. Great price and fast shipping from etrailer.
Pin appears to be of good quality but will not fit a 2019 Toyota Tacoma OEM hitch. Too narrow.
Overall this is a great hitch lock. I purchased it primarily because it is stainless steel, rather than plated steel like my old lock, which ended up with a lot lot of surface rust. I like the "push button" lock feature as it allows you to lock the lock without a key and visually tell that it is locked. There is one potentially major flaw with this lock that I did report to etrailer months ago and I do not know if has been addressed. After winter I tried to unlock the lock and could not do so (the locking button would not pop out). It took me about an hour of fiddling with it, using WD 40, to get the thing open. Evidently a bit of water got into the lock and although most of the lock is stainless steel the little spring-loaded ball bearing that actually engages the locking mechanism is not. It had rusted quite severely. Since then I've kept the inside of the lock well greased and it's worked OK. The ball bearing should also be stainless. This little oversight could be a huge deal if you were on a trip and couldn't unlock your hitch from your vehicle.
The ordered item is one of many I've ordered from etrailer. These people are customer intensive with all sorts of help and information that is needed to make an intelligent, knowledgeable very useful purchase. They tell you what you need to know.
Great company! Helpful and good product s.
