Blue Ox Trailer Hitch Receiver Lock - 5/8" Diameter - BX88212

Average Customer Rating:  4.7 out of 5 stars   (43 Customer Reviews)

Secure your Blue Ox tow bar to your RV's trailer hitch receiver with this 5/8" diameter lock. Snap-on cover keeps the keyway free of debris.


Fits up just fine. Using to secure my drop receiver to my truck. No issues.


I needed something more secure than the snap-lock pins that lock the deck of my tow dolly in the down position for towing with the vehicle on. The manufacturer and replacement pins I used keep coming loose and lost in transit. etrailer was the only retailer I could find that sells a locking hitch pin with a more than 4" working length. This Blue Ox is expensive but is solid and should be the last pin I need to buy for my tow dolly.


The hitch pin itself appears to be a well-made, functional product. My problem is that I purchased it for my 2018 Chevy Duramax 2500HD. As those of us who own 2500HDs know, the hitch receiver is a 2.5" receiver rather than a 2", so that it can accommodate Class V hitch equipment. Most locking hitch pins are too short to work effectively which is why I purchased this one. Unfortunately, it appears that the way the tow-chain holes on Chevy's hitch are positioned, this pin blocks the use of the holes with the chain/hook makeup I've got. Will probably need to purchase shackles for the chains to make everything work correctly.


Well I ordered this item from you because the hitch on my truck is 4” wide. I could not find a locking pin long enough that would fit my hitch locally. I tried at several Walmart stores and several Auto part stores and nothing. So I went to the internet and found this the BX88212 and it is just what I needed. It’s on my hitch and I’ll use it every time I pull my ATV utility trailer or my RV. Now I know where to look if I need anything else for towing. That’s at Thanks you and I really appreciate it!!


The pin is very heavy and I am very comfortable using it with my camper. I was concerned about buying a cheap inferior product that would not do the job. This is a quality name and great price. I hope I can buy a 2nd one keyed the same.



still awesome


the locking pin works great and the roller wheels look like they will work great on the back of my car trailer.


A quality looking and feeling item that appears to be worth its premium cost. This would have been a 5 star rating except for the cheesy little rubber band that holds the rubber cap that protects the lock from dirt and moister. The cap seems to be good enough but the little piece of rubber that holds it to the pin does not look like it will last very long. That being said I would still buy it again.


I ordered two of these for my B&W Stow Away hitch and they fit perfect. Ironically both came with same keyway, I did not expect that.


Delivery was fast, product fits perfectly, price was very reasonable


You even got the correct keys I needed with the lock. Great service!!!

Myron D.


The pin locks have 20,000 miles on them pulling a toad. Still working great and open easily every time.


Used for one year. Product is sturdy and works well. No problems. Rubber dust cover could be revamped for easier use, but very minor detail.


Just what I needed for securing trailer mover to trailer. Very well made. Fast delivery. Already in use.


I had a difficult time finding a lock long enough for my adjustable hitch. This fits perfectly!


Sometimes the lock is a little tough to get off. Other than that these have been perfect.


They have arrive today. Now gonna put them to use for fuel tank locks.


I wanted a longer pin lock and this is it. Very strong and good quality.


Perfect for locking your hitch. I’d highly recommend!




Very well. The baseplates fit very well . I just ordered baseless for my new Bronco!!


Solidly build and key works although it is not as pictured. The product I received had a round key not a standard "toothed" key.


I needed a span more than 4.25". This was hard to find but was the perfect find. Nice quality and recommended if you need the extra span.


Put it on and forgot about it. It works as it should.


Quick shipping good quality products will do business again if I need anything


I am really tickled with my order it worked perfectly




Well made,but the cover is hard to remo ve.

  • Availability of Locking Hitch Pin with 4-1/2 Inch Usable Span
    The closest option we have available to what you are needing is the Blue Ox Trailer Hitch Receiver Lock # BX88212. This heavy-duty lock features a 5/8 inch diameter and a usable length of 4-3/8 inches. This usable length represents the longest option we have available for standard locking hitch pins. We do have a couple options that are slightly longer, but they feature uniquely threaded ends that are only designed to fit certain model bike rack shanks. I have attached a short video demonstration...

  • Hitch Lock Recommendation for 3 inch Trailer Hitch
    For a 3 inch hitch like what you have a larger hitch lock like the Blue Ox part # BX88212 would be an excellent option. This has a usable span of 4-3/8 inches which would be enough for a 3 inch hitch. This is a higher quality lock that we have found holds up well over time too.

  • What Does the Span of a Locking Hitch Pin Refer To
    The span of a locking hitch pin like the Blue Ox # BX8858 means the amount of space that can fit between the two walls of the hitch receiver- so yes, basically the distance from the outside wall of one side of the receiver to the other. We have noticed that certain Toyota factory hitches have a thicker walls on their receivers that measure 2-7/8" instead of just under 2-3/4" so if you've got a Toyota truck with a factory receiver you would need to use a locking hitch pin like the # BX88212...

  • Hitch Receiver Lock for Toyota Tacoma OEM Receiver Hitch
    The OEM receivers on the newer Tacoma and Tundra models are wider than what's usually seen, so a longer lock is needed (as you seem to already know). We came up with a lock that has a inside span of 3-5/8 inches which works perfectly with those Toyota OEM hitches, part # e98881. The Blue Ox # BX88212 would also work, as its inside span is long enough, but our option is less expensive, so that's what I'd recommend.

  • USA Made Hitch Lock for 2019 Toyota Tacoma

  • Three Locking Hitch Pins for Class V 2-1/2 Inch Hitch Receiver that Can be Keyed Alike
    We do have a way for you to lock your ball mount to your hitch receiver but unfortunately, the Blue Ox # BX88212 is not able to be keyed alike. For another solution,our lock # e98881 fits 2-1/2 inch Class V hitch receivers and can be keyed alike. Just select the drop down to do so on the product page when ordering. Hitch pins don't actually bear any of the trailer's weight so they are not given a weight rating. They are tested to be used with a Class V hitch and therefore...

  • How to Order InfiniteRule Hitch Locks to All Use Same Key
    With the InfiniteRule brand of locks like the part # 34061071-D it's pretty easy to order several and have them all use the same key. You'd need to select the "keyed alike" selection from the drop down menu on the product page of each lock and when we fill the order we will make sure that each of the locks uses the same key number. I attached a link to a page that has all of the InfiniteRule locks we have for you to check out as well.

  • Recommended 5/8 Inch Diameter Trailer Hitch Locks Keyed Alike
    For your 5/8 inch diameter hitch pin lock, I recommend our Hitch Receiver Lock - Stainless Steel Flush Design for 2" Trailer Hitch Receiver # e98882 that can have any quantity you desire keyed alike. Blue Ox does not offer a keyed alike option on their hitch locks and we don't carry Connor products.

    Although there is an option for a trailer hitch receiver lock for a 2-1/2" trailer hitch that you can get keyed alike, the Blue Ox Trailer Hitch Receiver Lock # BX88212 is not one that you can get keyed alike. I recommend the Trailer Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # e98881 which has a keyed alike option. To order them keyed alike, just hit the "Keyed Alike" option in the drop-down box on the product page and enter the quantity you need. I added...

  • Stainless Steel Hitch Lock that Fits 2-1/2 inch Trailer Hitch
    Since hitch pins don't typically carry the weight of a trailer they are not weight rated. Normally it's the tongue weight of the trailer that pins the ball mount to the hitch tube which keeps it in place and not the hitch pin. This is not stainless but we have the part # C23519 which is similar and is stainless.

  • Long Locking Hitch Pin Needed for Class V Trailer Hitch on a Chevy K2500 Pickup Truck
    You might be able to use Blue Ox pin # BX88212 which measures 4-3/8 inches between the ends so it will work. The best way to measure to ensure the clearance needed is to use a tape measure that is small enough to fit through the hitch pin holes. Then measure the outside to outside width of the hitch that way.

    If you have a Lock N Roll Articulating Hitch such as the # 336VS511 we have a solution. While Lock N Roll does not offer a locking pin for the ball mount portion the Fastway Hitch Lock part # FA86-00-3660 fits.

  • Longest Trailer Hitch Lock for 10 Locks Keyed Alike
    The Blue Ox # BX88177 consists of two 1/2 inch diameter and 2 5/8 inch diameter pins. They are only able to have the 4 keyed alike. The measurement is 4-3/8 inches between the opening like # BX88212 which cannot be keyed alike . The only option to get all ten keyed alike is to use the DeadBolt Trailer Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # e98881 which measures 3-5/8 inches between the outside cylinders. I've attached photos to assist.

  • Locking Hitch Pin for 3 Pins on B&W Tow & Stow Ball Mounts for 2-1/2 Trailer Hitch
    The Bulldog Hitch Receiver Lock # BD580412 that you referenced is a little short for the adjustable part of the B&W Tow & Stow 2-Ball Mount # BWTS20037B but we do have something that will work instead. The Blue Ox Lock # BX88212 measures long enough to fit the Tow & Stow!

  • Locking Adjustment Pins for the B&W Tow & Stow 2-Ball Mount Part # BWTS10037C
    Yes, in order to prevent the adjustment pins part # BWTS35010 from being stolen on your B&W Tow & Stow 2-Ball Mount part # BWTS10037C you are going to need a hitch pin lock that has a 5/8" diameter and at least 4-1/2" span. For this, I recommend the Blue Ox Trailer Lock part # BX88212 which is one of the very few options that meet the above criteria. Please keep in mind that the built-in channel prevents removal of the platform when the ball mount is installed, which will help prevent theft.

    The B&W Defender Locking Gooseneck Coupler Inner Tube - Round - 2-5/16" Ball - 25,000 lbs # BWGNC4250 would require an incredible lifting height of the trailer steadily straight up to release a trailer when locked at the coupler to the hitch ball. That is the only reason it doesn't come with the locking pin you referenced.

  • Recommended Trailer Hitch for a 2019 Nissan Titan SV
    Out of the Draw-Tite # 76154 and the Curt # C13304 trailer hitches I recommend the Curt option for your 2019 Nissan Titan SV because Curt tends to have stronger welds and a thicker powder coat which gives it better protection. Both options have the same weight ratings and so it really boils down to construction, for which Curt takes the prize. Since most people who install trailer hitches on pickups typically use it for towing you'll also need wiring and a ball mount to complete a towing...
