Toyota Tacoma trucks have a double width at the hitch pin area that is exactly 3". So, you're stuck buying a larger pin than necessary. This pin has a 3" span and it's made for the 2" hitch. Problem solved!

Still a great piece.

Perfect. Good price for the quality. Although I didn’t need the sleeve for the application, it’s a nice benefit to give the item multi-purpose.

Ive been using it almost every day since purchased. Still works fine. I use it to secure a bike rack to a jeep wrangler.
Tom J - 01/30/2022

Sturdy lock but difficult to work the mechanism, especially when fumbling under the receiver hitch.

- BD580405

does what it's supposed to. My second one. would buy again. You do need to maintain it if you leave it on during winter. Lube and clean it periodically or it will freezeup. Seems like there might be something internal that isn't stainless, i recall seeing some rust on my old one and it froze up, but i was able to clean it with some Evaporust and WD-40. Maintain it periodically and it will last for a long time.

- BD580405

Works as advertised.

- BD580405

Master lock. Solid and dependable. This lock includes a sleeve that will accommodate 1 1/4" and 2" receivers. I have the smaller hitch (1 1/4") but it's nice to have options. The main shaft of the lock is longer than I expected but could be used to attach a couple of chains if your hitch doesn't happen to have chain connects. Shipped and received right on time. Thanks, etrailer. Keep up the good work!

Works great

Exactly like the information on the product. We haven't used it yet, as we haven't received our carrier.

I got the lock so no one will take the skull off of my girl friends truck

- BD580405

I received it on time and am very happy

- BD580405

Product does not fit hitch. I will be returning. The package took a long time to arrive once ordered. I expected quicker delivery.

  • 2019 Toyota Tacoma Hitch Lock Recommendation
    We have the Trailer Hitch Receiver Lock # BD580405 which has a usable span of 3 inches which would work great for you. It was designed for bigger hitch sizes but it has the same 5/8 inch diameter as what you'd need too so it would work great.

  • Does BulletProof Hitches Adjustable 2-Ball Mount # MD256 Come with Hitch Pin
    You will need to buy a hitch pin separately from the BulletProof Hitches Adjustable 2-Ball Mount # MD256. For that we have an option for a locking hitch pin like the part # BD580405 or for a standard hitch pin part # C21500.

  • Is A Receiver Pin Lock Okay to Use Instead of Threaded Pin for Bike Rack
    As long as the Bulldog Trailer Hitch Receiver Lock # BD580405 fits with the bike rack then you should be okay to use it with an anti-rattle like the etrailer # e99007 to help limit the movement of your bike rack. With that being said, if we carry the manufacturer of the bike rack you have, just let me know and I can see if we have a threaded pin that also includes a lock just so that you can get much more of a clean install and you are using products that you know are designed for the...

  • Replacement Part Availability For Older Thule Rak-N-Loc Bike Rack
    Since the Thule Rak N Lok has been out of production for quite a few years, Thule does not have any specs or information regarding replacement parts. That said, I will do my best to provide some helpful information or parts that may work. Erailer Trailer Hitch Receiver Lock for 2" Hitches - Flush - 2-5/8" Span - Chrome # e98880 would likely work if you have a 2" receiver, but you will want to measure a few things to verify fitment. Make sure there is less than 2-5/8" from outside edge...

  • How To Use 2 Bike Rack In Class II Hitch For 2018 Chevy Trax
    Do not sell your bike rack yet! I recommend to use the Class II 1-1/4" Draw-Tite Trailer Hitch Receiver part # 36554 on the 2018 Chevy Trax Premier. There are currently not any 2" hitches available for the Trax because the vehicle is not designed to a tow a trailer but is capable of carrying accessories like a bike rack or cargo carrier. Since your bike rack is designed for 2" hitch receiver openings you can use the Brophy Trailer Hitch Receiver Adapter part # HT5R which will adapt the...

  • What Hitch Reducer and Locking Hitch Pin Do You Recommend for a Curt 5 Bike Rack on a 3-Inch Hitch?
    In order to use the Curt 5 Bike Rack - 2" # C18065 on your 3-inch hitch on your RV, I recommend the Curt Hitch Receiver Reducer Sleeves - 3" to 2-1/2" or 2" # C45408. The reducer will allow you to use the Curt 5 Bike Rack with your 3-inch hitch receiver. As for as a compatible pin and lock that will work for both the hitch, the reducer, and the rack, I confirmed with my contact at Curt that the pinhole diameter of these accessories is 5/8". With that being said, I recommend the Fastway...
