Bulldog Hitch Locks - BD580402

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.


Features:

  • Flush-style trailer hitch receiver lock is used in place of standard pin and clip to prevent theft of ball mount or hitch-mounted accessory
    • Secure your bike rack, cargo carrier, hitch cover and more to your trailer hitch
  • Ball-bearing locking system provides maximum security and ease of use
    • Just pop the deadbolt onto the end of the pin and the lock will automatically engage
    • Grease ball-bearings periodically to ensure smooth operation
  • Solid stainless steel pin offers superior strength and durability and is corrosion resistant
  • Plastic cap covers key slot to help prevent corrosion in the locking mechanism
  • 2 High-security, square keys included


Specs:

  • Application: 2" x 2" trailer hitch receivers
  • Inside pin length (span): 2-1/2"
  • Pin diameter: 5/8"
  • Limited 1-year warranty


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.

Video Transcript for Bulldog Locks Hitch Accessories BD580402 Review

Today were going to review part number BD580402. This is the Bulldog Lifelong Trailer Hitch Lock for 2-inch hitches. This is a flushed style trailer hitch receiver Lock which will be used in place of standard pin and clip to prevent theft of the ball mount or any hitch-mounted accessories. This will secure your bike rack, cargo carrier, hitch cover or any other hitch accessory to your trailer hitch. It does have a ball-bearing locking system. I just want to show you that.

Theres the ball-bearing locking system which will provide maximum security and ease of use. What you end up doing is you can just pop the deadbolt onto the end, push that and it will automatically engage as a solid stainless steel pin which will offer superior strength and durability. The pin is right in there. It is rust proof. This whole lock is a stainless steel construction.

It does have a plastic cap which will cover the key slot to help prevent corrosion in the locking core. It does come with two high security square keys, and again, this thus fit the 2-inch trailer hitch receivers. Now, the inside pin length is 2-1/2 inches. The pin diameter on this is 5/8 of an inch. This does come with a limited 1-year warranty.

Basically, I just want to show you how this operates. If you take the key, insert it into the lock, turn about a quarter of a turn and the button will pop out. You can remove it from there. Now, this will insert into the hitch pinhole in your receiver. Then, then when it goes on the other end, you edges, push that on, push that in and it will be locked into place.

Then, put your plastic cover over to protect the locking core. Now, this ball-bearing system on this Lifelong Hitch Lock is easy to use. It ensures structural integrity of the pin. A typical padlock-style hitch lock has a significant taper at the end of the pin when the lock snaps into place. This tape will actually weakens the pin, making it easier to break or cut. Because this uses the ball-bearing locking system on this Lifelong Lock, there is no taper 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. That should do it for review on part number BD580402.

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

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

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

Not 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

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

This trailer pin is stainless steel rather than chromed steel which means no rusting. Also the key goes in from the side and the rubber cap fits snuggly so hopefully the tumblers inside the lock will stay dry and free from water and road salt which is what killed my last locking hitch pin. Time will tell but this seems like a quality piece. 190589

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

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

Tha Bulldog trailer hitch lock I purchased works great. The quality and sturdiness match the reviews! It works much better than the other locks I have tried.

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. 193000

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

This is a solid pin sold by a great vendor. Very strong and doesn't trust. (I don't leave my ball mounts in the receivers 24/7/365) Didn't give it 5 starts due to the small amount of fiddliness I get while trying to work the jet to unlock it. Usually have to use one hand to hold the lock barrel still and the other hand to work the key it else the entire barrel keeps turning. Not the end of the world it a tiebreaker. 309375

Could very well be the very best receiver lock I have ever had in over 35 years of fishing, pulling bass boats. BUT, there is a small rubber o-ring inside the locking portion that does not stay seated - have to be very careful to make sure this locks when button is pushed as can easily appear and seem to be locked but will frequently "false" lock when the o-ring binds up, not staying in the groove. Answer seems to be to keep the o-ring in the groove but easier than it sounds? Hopefully I get it figured out? 111539

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. 112085

The lock has not rusted. It fits securely. The key hole cover was switched out by me with a rubberized cap.

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. 320518

Received the trailer hitch lock and it worked fine right out of the box. I exercised the key and bolt as I would when I plan to install it on my hitch and I feel comfortable that it's strong and will work great. I marked the item down because the rubber cover fits loose (the video review I saw of the item commented on the cover as preventing moisture and debris from getting into the key chamber during use) and I expect to lose it soon after I get on the road. It may just be this particular rubber cover that's been stretched out on this one item. Otherwise it will work for what I need. 420401

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... 455081

  • Solution for Freeing Up Bulldog Lifelong Hitch Lock

Spray on the latch end of the lock as well to see if you can get it to soak in from the back side.

For a 2-1/2-inch hitch I recommend the B&W # BWTS51235. Any lock, even one made of stainless steel, will benefit from you occasionally removing it from the hitch...

  • Does Dead Bolt Trailer Hitch Lock Part # 7683 Fit a Class ll 2-Inch Trailer Hitch Receiver
  • Dead Bolt Trailer Hitch Lock Part # 7683 uses a 5/8-inch pin to lock your ball mount or hitch-mounted accessory to your trailer hitch. This is intended for class III and class IV receivers. Typically class II receivers have a 1-1/4-inch opening and use a 1/2-inch diameter hitch pin. Once you confirm your receiver size (please refer to the included article) you can select either a 1/2-inch diameter hitch lock, such as part # RH2-XL or # 5200 for a 1-1/4-inch receiver, or if a 2-inch...

  • Recommended Hitch Mounted Spare Tire Carrier Compatible With Bike Rack
  • There is one spare tire mount made for an application like this. It is the Roadmaster Hitch Mounted Spare Tire Carrier w/ 2" Receiver Opening - 2" Hitches # RM-195225. This will give you a spare tire holder that can swing down for easier removal and will give you a 2 inch receiver for a bike rack. I recommend using a lock like # 4324 to secure your spare and a hitch lock like # BD580402 to secure your accessory. For a bike rack, I recommend the Swagman Dispatch 2 Bike Platform Rack...

  • Hitch Receiver Lock Recommendations For Aftermarket Trailer Hitch
  • The Bulldog Lifelong Trailer Hitch Lock, part # BD580402, is designed to work with hitches that have a 2 inch by 2 inch receiver opening. The lock has a 5/8 inch pin diameter and will not work if the hitch outside dimension is bigger than 2-1/2 inches. If you measure the outside dimension of your hitch and find that it is longer than 2-1/2 inches then the DeadBolt Trailer Hitch Receiver Lock, part # RH5-XL may work better for you. This is an extra long 5/8 diameter stainless steel pin...

  • Is Bulldog Lifelong Trailer Hitch Lock # BD580402 for 2-Inch Hitches Considered Universal
  • The Bulldog Lifelong Trailer Hitch Lock # BD580402 for 2-Inch Hitches is a general-purpose 5/8-inch diameter hitch lock intended for standard 2 x 2-inch trailer hitch receivers. It is not described as a universal-fit item though it will fit the majority of 2-inch receivers with the exception of some factory hitches that have an outside width greater than 2-1/2-inches. Bulldog describes this a Lifelong lock due to its stainless steel construction and reliable ball-bearing lock mechanism. The...

  • Stainless Steel Hitch Lock Recommendation with a 3-1/2 inch Usable Span
  • The Tow Ready Trailer Hitch Receiver Lock # TR63252 that you referenced is all stainless steel and has a span of 3-1/2 inches so it should work well for you. I attached a review video for this lock for you to check out as well. The # BD580402 that you referenced only has a 2-1/2 inch span.

  • Recommended Weight Distribution System For 2014 Ford F-150
  • For your 2014 Ford F-150, you will not need to modify your factory hitch to use a weight distribution system with the travel trailer you mentioned. When looking at weight distribution, you want to consider the loaded weight of your trailer tongue as well as any cargo behind the rear axle of your truck to determine the total tongue weight. You want that total tongue weight to fall as close as possible to the middle of the tongue weight range of your weight distribution sysem. With the...

  • Can the Roadmaster Hitch Mounted Spare Tire Carrier Tow a Trailer
  • The Roadmaster Hitch Mounted Spare Tire Carrier # RM-195225 referenced in your question is designed for mounting hitch accessories and flat towing. The manufacturer states that this product is not rated for towing a trailer. The spare tire carrier does have a tongue weight of 400 pounds and flat towing capacity of 10,000 pounds, but keep in mind that using the carrier will reduce the tongue weight capacity of your trailer hitch by 33 percent. This is a great option for carrying your...

  • Do Locking Hitch Pins Have Weight Capacities
  • Hitch pins do not have weigh capacities because they do not actually support any of the weight of the trailer. When there is 10-15% of the tongue weight of a trailer's total weight applying vertical force on the ball mount it actually is so bound up in the hitch that the hitch pin doesn't actually keep the ball mount in the hitch. In your case it would be the 1,200 lbs of tongue weight on the ball mount that keeps it from sliding out of the hitch. So the part # BD580402 would do a great...

  • Can the Bulldog Locking Hitch Pin # BD580402 be Keyed to Match Key # LB011
  • I spoke with my contact at Bulldog and she told me that the Bulldog Trailer Hitch Lock, # BD580402, could not be keyed to match key number LB011. This lock is not available keyed alike. If you would like hitch locks that can be keyed alike and that can be keyed alike in the future, I recommend looking at the Deadbolt Trailer Hitch Receiver Lock, # 40107. This lock also uses a solid stainless steel pin and works with 2 inch Class III and Class IV trailer hitches.

  • Does the Bulldog Lifelong Trailer Hitch Lock Have Stainless Steel Ball Bearings?
  • The Bulldog Lifelong Trailer Hitch Lock for 2" Hitches - Flush - 2-1/2" Span - Stainless # BD580402, has a rustproof stainless steel construction. I reached out to my contact at Bulldog and he said the ball bearings are made of plated steel because stainless steel likes to bond with stainless steel. The plated steel gives it the ability to function correctly, but he also said lubing them is important to keep them functioning correctly. I've attached some review videos for you.

  • What is the Bolt Pattern Range for the MaxxTow MaxxHaul Portable Vise Plate # MT80356
  • The slots on the MaxxTow MaxxHaul Portable Vise Plate # MT80356 are symmetrical so they are even all the way around. The closest part of any slot to the next one over is 4 inches which means the smallest bolt pattern it can hold is 4 inches x 4 inches. The largest part of any slot to the next one over is 6 inches, meaning the largest bolt pattern is 6 inches x 6 inches. I have attached a picture to demonstrate these dimensions for you. If your vice is too small, we do carry 3 vices that...
