Features to know about

Rust Resistance That Lasts: Solid Stainless Steel Construction

If you're tired of rusted hitch locks, look no further than the Bulldog Lifelong Trailer Hitch Lock. Crafted entirely from high-strength stainless steel, this lock is designed to withstand the test of time and the elements, providing superior strength and corrosion resistance. Its solid construction ensures it stays in peak condition even on coastal roads or during harsh weather conditions.

Effortless Security: Ball-Bearing Locking System

Say goodbye to frustrating hitch locks that are difficult to operate. With the Bulldog Lifelong's innovative ball-bearing locking system, securing your hitch accessory is as easy as popping the deadbolt onto the pin's end. The unique design automatically engages the lock, ensuring a maximum security setup that's user-friendly. No more struggling with awkward padlocks – just a quick push, and you’re done!

Power Through Your Adventures: 5/8" Diameter Pin for Standard Hitches

For those who love weekend getaways and spontaneous road trips, having a reliable hitch lock is crucial. The Bulldog Lifelong comes with a robust 5/8" diameter pin, perfect for securing your 2" x 2" trailer hitch receiver. Whether you're hauling a bike rack, cargo carrier, or tow bar, you can rest assured knowing your gear is locked tight and theft-resistant.

Sleek and Snug: Flush Design with a 2-1/2 Inch Span

Bulky locks aren't just cumbersome; they also risk getting caught on surroundings. Thankfully, the Bulldog Lifelong Lock's flush design with a 2-1/2-inch span gives you peace of mind, fitting snugly without any protruding parts. This minimalistic approach ensures your vehicle retains a clean, streamlined look while providing extra security against unauthorized removals.

All-Weather Performance: Innovative Plastic Cap

Protecting the internal locking mechanism from dust, moisture, and debris is a breeze with the included plastic cap. Specifically designed to cover the key slot, this cap prevents unwanted elements from corroding the lock's internal parts, maintaining smooth operation over time. Keep your lock functioning like new, even after years of hard use.

Universal Fit Design: Fits Most 2-Inch Hitches

The Bulldog Lifelong Hitch Lock is engineered with a 2-1/2 inch inside pin length, making it compatible with the majority of 2-inch receiver tubes. This universal fit means it adapts to a wide array of vehicles and hitch setups, saving you the headache of searching for hitch-specific locks. Whether you own multiple vehicles or change trailers often, this lock has you covered with reliable versatility.

  • 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 # e98892 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...

  • Is There A Version Of The Bulldog Hitch Lock BD580402 Available For Class I Hitches?
    Hi Richard! I do have a fairly similar option, but we do not have a version of the Bulldog Lifelong Trailer Hitch Lock for 2" Hitches # BD580402 available for 1-1/4" hitches, unfortunately. The Flint Hill Goods Lock for 1-1/4" & 2" Hitch - 2-3/4" Span- Black # FHG34ZR would be the closest match we currently carry. It is a bit different, but I actually prefer the barrel style key as I think they are easier to use. Especially when you cant really see what you are doing. Are you wanting...

  • Locking Hitch Pin Recommendation that Wont Rust
    It sounds like you are looking for a replacement locking hitch pin since you said the lock pin of your hitch. For a locking hitch pin I would recommend the Bulldog Trailer Hitch Lock part # BD580402 as it is stainless steel which is rustproof.

  • Does Hitch Pin Lock Have a Normal Use
    There is not necessarily a specific lifespan that can be counted on with hitch lock like your Blue Ox Trailer Hitch Receiver Lock for 2" Hitches # BX8858. If it gets used heavily and a lot of stress on it then a lock can wear down quicker than those that are used somewhat sparingly, but less than a year old is not a lot of time for the issues you are having. There are hitch locks for a 2" hitch that have warranties, such as the Trailer Hitch Receiver Lock # e98880 and Bulldog Lifelong...

  • Recommended Towing Setup For 2017 Audi Q7
    For your 2017 Audi Q7, if you don't already have a hitch I recommend the etrailer Trailer Hitch Receiver - Custom Fit - Class III - 2" # e88KR. This hitch receiver is a matte black powder coat finish over and e-base coat for excellent rust protection. For your wiring, I recommend the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT if you don't have the factory tow package. This harness uses zero-contact-interface sensors...

  • How To Prevent Trailer Hitch Pin Lock From Seizing
    I am sorry to hear about the issues you are having with the Trailer Hitch Receiver Lock part # e98880. The main way you are going to be able to preserve it is to make sure you keep the dust cover, Replacement Dust Cover for Deadbolt Hitch Lock part # e98923 over the keyhole. In addition to keeping the key hole covered I would A) spray some penetrating grease down in the keyhole every couple of months and B) insert the key and turn the lock core back and forth every couple of months as well....

  • 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...

  • Recommendation for Most Secure Trailer Coupler Lock
    The more secure coupler locks we offer are designed for be used when the trailer isn't hitched to the vehicle. They're designed to prevent the coupler from being hitched to a trailer ball, like # FA86-0015-305. With the trailer attached to the ball, you'd want to use something that would prevent the latch mechanism of the coupler from being opened, as well as securing the ball mount into the hitch receiver using something like the # BD580402 hitch lock you'd looked at. The latch locks...

  • Recommended Towing Set-up For 2009 Chevy Traverse To Tow 5500 lb Travel Trailer
    For your 2009 Chevy Traverse, lets start at the very beginning so I can walk you through parts needed. If you do not have a trailer hitch receiver, I recommend the Draw-Tite Class III # 75528. This is a very strong hitch that will meet your towing needs. If you don't have a ball mount, I recommend using the etrailer.com ball mount kit # 989900 that will give you different rise and drop options along with different hitch ball options to tow a trailer level. For vehicle wiring to tow...

  • Solution for Freeing Up Bulldog Lifelong Hitch Lock
    There is some component of the Bulldog Lock part # BD580402 that has seized up. If the lock isn't on a vehicle you would want to let it soak in some gear oil overnight to try and allow it to free itself up. If it's on a vehicle you would have to continue soaking it with lubricant and trying to work it free. Spray on the latch end of the lock as well to see if you can get it to soak in from the back side.

  • Trailer hitch Lock for Use on a 2015 Chevy Silverado with a 2-1/2 Inch Hitch and Reducer Sleeve
    You will actually need a longer hitch pin to fit all the way through your 2-1/2 inch hitch on your 2015 Chevy Silverado. Bulldog lock # BD580402 does not have a long enough useable span for a 2-1/2 inch receiver. The lock I recommend for you is our lock # e98881. It has a useable span of 3-5/8 inches. I have linked a video review of this lock for you.

  • Cargo Carrier Compatibility with SUV Tent
    If you're referring to the use of a cargo carrier, the tent will provide enough room to use both products together. Of course, the cargo carrier will protrude into the tent area. For a tent, I recommend the Rightline Gear SUV Tent with Rainfly - Waterproof - Sleeps 4, Item # RL110907, which is confirmed to fit your Honda CR-V. The tent also disconnects from your vehicle to be used separately, so you wouldn't have to leave it connected to your vehicle with the cargo carrier. For a cargo...

  • 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...

    There is only one hitch mounted spare tire carrier I know of that has a folding option. It is the Roadmaster Hitch Mounted Spare Tire Carrier w/ 2" Receiver Opening - 2" Hitches # RM-195225 and is made for RV. This is made to maintain the use of the hitch for mounting accessories or flat towing, but not for towing a trailer. It holds 16 inch to 24-1/2 inch spares with any bolt hole pattern. This will allow rear door access to your Dodge Trademan Camper Van. I recommend using the etrailer.com...

  • Looking Hitch Pin Recommendation for a 2012 Ford F-150 with 2-1/2 Inch Trailer Hitch Receiver Span
    It will be a snug fit so if the outside of the receiver on your truck is 2-1/2 inches locking pin # BD580402 should fit. On each end of the pin, on the insides that face the inner span, it is tapered so there will be just enough wiggle room. It might be safer to go with span that is just a little wider like # e98880 that has a 2-5/8 inch span. Then there is an extra long span on # e98881 that measures 3-5/8 inches inside width. If 3-5/8 is too long and you do not want to chance a 2-5/8,...

  • 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 spare...

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 # e98881 may work better for you.

  • 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.

  • 2-1/2 Inch Span Bulldog Lifelong Hitch Lock Recommendation

  • How Many Different Key and Lock Combinations are there for Bulldog Hitch Lock # BD580402
    I spoke with my contact over at Bulldog and found out that they periodically make slight changes, different locks, and matching keys for lock # BD580402. So there are thousands of possible key combinations for this lock. Also, the key is very unique and cannot be duplicated like you could with a traditional house key. Duplicates have to be made by Bulldog.

  • Does Bulldog Trailer Hitch Lock for 2" Hitches, Part # BD580402, Affect Towing Weight Rating
    The Bulldog Trailer Hitch Lock for 2" Hitches, Part # BD580402, will not affect the gross towing weight capacity of your Class IV hitch receiver. (Typically all hitch pins are rated well in excess of their actual load requirements.) Since this product is constructed of solid stainless steel it is actually stronger than a standard 5/8-inch diameter pin. The inside pin length is 2-1/2 inches making for an easy fit in 2-inch receivers. I have included a link to a product review video for...

  • Recommended Hitch Lock For a 2022 Ram 2500 With a 2-1/2" Receiver
    I recommend the BOLT Trailer Hitch Receiver Lock # BL7018448 for your 2022 Ram 2500, John. This will fit your 2-1/2" receiver and best of all you will key it to the truck key so there are no additional keys to lose. It is also a stainless steel construction so it will not corrode away like your last one. Bulldog does not offer a lock like the Lifelong Trailer Hitch Lock # BD580402 for a 2-1/2" receiver.
