Bulldog Trailer Hitch Lock - BD580401

  • Fits 2 Inch Hitch
  • Bulldog
  • Standard Pin Lock
  • Keyed Unique
  • 2-1/2 Inch Span
  • Steel
  • Flush Pin

This solid, high-strength steel, 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. Chrome finish guards against corrosion. 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 steel pin offers superior strength and durability
  • Chrome plating resists rust
  • 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


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.


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.

Have a 98 4-Runner with the factory towing pkg. This pin fits perfectly. Some folks were concerned about the protective lock cap not being snug enough but this one was tough to remove; maybe it will loosen over time. Works a bit stiffly right now, but that will most likely loosen up as time passes. I mean, it just arrived today. All in all, this was a good buy at a good price. 330822

Ask the Experts about this Bulldog Trailer Hitch Lock

  • Can the Bulldog Lifelong Trailer Hitch Receiver Lock Be Physically Broken Off
    The Bulldog Lifelong Trailer Hitch Receiver Lock part # BD580401 is an extremely durable lock. It is designed to provide security for 2" hitch mounted accessories such as a ball mounts. In regards to security, I took a look at some of the reviews and there were no mention of the lock failing. That said, the mere presence of a lock can be enough to deter most thieves. To answer your specific question, no, I do not think a pipe could be placed on the end to snap the lock off. This is...

  • Does Bulldog Hitch Lock # BD580401 Have Weight Capacity
    Hitch pins and hitch pin locks like the Bulldog # BD580401 do not typically have weight capacities as they do not normally bear the weight of the trailer since the tongue weight pins the mount into the hitch tube. This would work well in a flat towing setup too even though the tongue weight isn't quite there.

  • What Diameters Are Available For Hitch Pins
    Hitch pins come in 1/2 inch and 5/8 inch diameters with the 5/8 inch being the most common. Since it sounds like your hitch pin hole has elongated, you should get a new hitch. Send me the make, model, and year of your vehicle and I will make a specific recommendation. For a 1/2 inch diameter hitch pin, I recommend the Curt Class I and II Pin, Item # C21403, for a basic pin or the Master Lock Trailer Hitch Pin, Item # 1472DAT if you need one that locks. For a 5/8 inch pin, I recommend...

  • Recommended 2 Trailer Hitch Receiver Lock That Can Be Keyed Alike
    I do have a great alternative for you, however the Bulldog Lifelong Trailer Hitch Receiver Lock # BD580401 cannot be keyed alike. If you were to order multiple sets they would all likely use a different key. For a very similar unit that can be keyed alike I highly recommend the etrailer.com Trailer Hitch Receiver Lock # e98880. Like the Bulldog model you were looking at this is designed for 2 inch trailer hitch receivers, features a chrome plated construction to help with resisting...

  • Will the Bulldog Receiver Lock Part # BD580401 Fit a 2" Trailer Hitch Curt Part # BD580401
    Yes, the Bulldog Lifelong Trailer Hitch Receiver Lock part # BD580401 will work with the Curt Trailer Hitch Receiver part # C13163 which is a fit for your 2017 Mitsubishi Outlander. It is rated for use on Class III-V trailer hitches and also has a unique ball-bearing locking cylinder which ensures smooth operation. I have attached a review video of the lock and install video of the trailer hitch for you as well.

  • Hitch Lock for the Factory Trailer Hitch on a 2013 Ford F-150
    The width of the factory trailer hitch on your 2013 Ford F-150 is just slightly too wide to use the Bulldog hitch lock # BD580401. It has a usable span of 2-1/2 inches so it is just 1/16 of an inch off. I recommend lock # e98880. This lock has a usable span of 2-5/8 inches which is 1/16 inches longer than your hitch width. I have included a link to a video review of this lock for you.

    The Curt Class III Hitch for your 2014 Chevrolet Silverado 1500, part # 13301, does require removal of the OEM light-duty bumper hitch. Both hitches cannot be installed at one time.

  • Can Pilot Ford Brake and Tail Light L.E.D. Trailer Hitch Cover # CR-017F be Used as Only Taillight
    The Pilot Ford Brake and Tail Light L.E.D. Trailer Hitch Cover # CR-017F is intended as a cosmetic accessory item. It is not DOT-approved as a brake/tail light for use on its own. All of your vehicle standard brake and tail lights must still be used along with this product.
