This solid, high-strength, flush-style hitch lock lets you secure your ball mount, bike rack, cargo carrier or other accessory to your 2" x 2" trailer hitch receiver. Rust-resistant stainless steel construction. 5/8" Pin diameter.

Specs:
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.

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. 672364
Takes a little fiddling to get the knack for operating this locking pin, but once you get the hang of it, it is no problem. 739927
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. 546966
From a retired Journeyman Machinist - Well designed - only improvement is use Carbon Fiber for main shaft. Inconel 300 would work also, but it is too hard to machine. It will be impregnable. Carbon Fiber is 5 times stronger than Stainless Steel, it will not break. Locking barrel is good as is. 661366
I purchased the Bulldog stainless hitch lock paired with pintle combo and solid 8 bolt adjustable hitch to work on a 1997 Dodge Ram 2500 cummins. She (the combo) is a thing of beauty and now ready to work. I felt like a proud father when the man in brown arrived with my baby. I expect to recieve many years of service from these items. Your teams service is second to none.We will be doing buisness again in near future. 109257
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! 371650
I live in SoCal about 3 miles from the beach so rust can be an issue. After 1 year the Bulldog Stainless lock has no rust and works flawlessly. Of course the plastic dust cover was lost almost immediately but since I'm rarely driving in dusty conditions it has not been an issue. 391741
Works exactly as expected. Great price and fast shipping from etrailer. 521231
Love it fits and works great 656933
Just installed the locking hitch pin on my receiver. Fit was excellent. I packed the lock mechanism with lithium grease as I live in New England and we salt the roads in winter. Time will tell what the winter salt will do to the pin, but I am hopeful that the stainless steel will hold up well for many seasons. Quality seems first rate, especially the lock unit, and the two keys supplied are heavy duty. Overall, very impressed. 600331
Very 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! 68397
Anthony - 08/30/2014Not a complaint about the construction of the product. Problem is that the fit up described for sizing the hitch based on the "box" did not work for my hitch. It appears that I need the next size length up (2.5"). The hasp lock fit fine and looks nice and sturdy. I will be returning for an exchange 441573
I 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. 544011
Using the internet I found what I thought to be the original such lockable trailer hitch and it was called the lifelong. It was in my opinion the best made thing on the market for that time and this one looks just like it even bearing some of the same name. So I bit. I got it but haven't unpacked it yet simply because I was perfectly satisfied it will be the best one for me so far as protecting my bike. I realize that won't comfort some of you, it's just the belief I have. No charge...Walt 328640
Really like ho this pin locks and is out of the way. Also has a dust cover for the key lock which has been great. 824902
Great product will buy more in the futu re 808979
This lock appears to be just what is needed. The full size shank from end to end will help foil a would be thief. The ball bearings need to have slight grease film on them to keep things from sticking, but the performance is looking great! I will update in the future if anything negative appears, until then I am extremely happy with this lock. This will spend it's life in MN. winters so I cannot afford to have failures. 806320
This is a very well made product that eliminates the problem of pin interference with factory chain attachment points on some vehicles. 796768
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. 793816

Worked great until winter then quit working the key won’t turn. I had to throw it away 778700
Nice design; reasonable price; quick delivery (despite COVID!). 773008
Very happy with the product. The same construction makes them rust proof. They function well. We have several and we would buy them again. 772127
