Specs:
Note: This lock will not work with some factory 2" trailer hitches that have an outside width 2-1/2" or wider.
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.

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.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.
It is OK but didn't fit my truck and I did not like it.It is made in china and was not as heavy duty as I would like. The tapered inside ends prevent it from locking on my 2 inch receiver. As a first time buyer from etrailer they customer service is excellent and the shipping is lighting quick. I purchased a Infinite Rule weight rated hitch pin from etrailer instead. Super heavy duty and U.S.A. made for my Gen-Y trailer hitch. A match made in towing heaven!
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.
these locks that we purchase were outstanding. they hold very in the desert environment aboard the MCAGCC base.
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.
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...
Very secure, works easily if you give it some lube in the tumbler and ball bearings occasionally. Holding up fine and gives you that peace of mind.
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.
Very strong material and compact fit. I sprayed it with silicone just to loosen up the lock a bit. I think it will work well for me.
Very nice product.
High quality, does everything advertised, easy to use. Very pleased with the purchase.
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.
This is an upgrade for me. I currently have a Bulldog Hitch Lock that Iv'e had for 6+ years but it is chrome. The chrome is starting to peel and rust so I purchased the stainless steel. These Bulldog pins are very well made and hade no issues with the locking mechanism.
Love this hitch! It is so versatile, makes towing different trailers much easier.
Bought this stainless steel pin to keep people from stealing my b and w drop hitch. My truck stays outside and my pin still looks new like the day I got it. And the rubber cap keeps the lock protected from the weather. Would recommend.
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!
Lock mechanism was a bit stiff, and inserting the key took some force, but fit was secure once I had it on. Finish is excellent, plastic cap for the keyhole is decent construction and long enough that it shouldn't come off easily.
I needed a very good hitch lock and I found it at e-trailers when I bought the Bulldog SS Hitch lock. It is an outstanding piece of equipment that is easy to engage and unlock. It is very strong metal and I will not worry about the safety of my trailer which I use frequently. I received the lock in a matter of days which I like very much. Customer service is excellent at e-trailers.
Works exactly as expected. Great price and fast shipping from etrailer.
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...
I purchased this for the rust proof property and the snap in locking feature. The key hole cover is flimsy. I switched it out for my old hitch lock cover. It has a band that fits perfectly around the top of the cylinder and a fold down cap.
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.
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!
Looks like great quality. And fast service too.
Just installed this. Fits nicely on the 2” receiver, not super long which is tidy. Clever lock mechanism.
