Five star service from etrailer, and maybe a two or three-star product from Bulldog. Aside from the rust and the fact that the collar is so stiff that it can't be operated by hand, the fabrication on the steel attachment plate is poor. The holes for the tongue jack are punched out, twice in some cases, resulting in an enlarged hole, but there are no threads for the tongue jack so you'll have to fumble around and use nuts underneath. The vertical angles on the steel are wrong, so it will splay out at the bottom and won't fit tightly to the A-frame and you will need to shim it out. The interior of the casting is full of weld spatter that will chafe the tow ball. I bought the less-expensive Ram sleeve-lock coupler under a Curt label and the fabrication is much better, having none of the problems the BullDog did. etrailer kindly sent me an RMA to return the BullDog.

We hate to see rust and other complications when it comes to the products that we sell. I have sent this information over to our customer service team for them to contact you.

The Bulldog coupler is SO MUCH easier to hitch up and disengage than my previous coupler which required several back and forth movements of my tow vehicle to engage/disengage the hitch ball.


A great product. The original crappy hitch on our new trailer was always a real pain to unhitch. Typically would have to keep the trailer wheels chocked and let the tow vehicle (no brakes and in neutral) roll forward or back freely while raising the tongue - only then would the ball be released from the ball socket. Not good when on a slope. A few times we actually had to pull out the 5/8" ball mount pin and drive forward and let the ball mount slide out of the receiver. No issues at all with the Bulldog hitch. And it's nice to have the positive and easy-to-verify clam-shell hitch mechanism instead of the sliding yoke lock of the original hitch. $200 bucks to have the old hitch torched and ground off and the Bulldog welded on. Money and time well spent.


My old bulldog took one for the team in an accident. This is the perfect replacement.


Perfect fit. Positive attachment to ball. Not worried about popping off.


Great product and shipping was so fast it was unreal.


great quality and works well.


Somehow my old hitch was damaged and a new hitch was required since the moving parts are not replaceable. The old hitch was a pain to use - it required an extra drop to get the ball into proper position, and it required my jumping on the bumper for extra lift to get the ball to release.

This hitch will solve the hard-to-attach, hard-to-release issues thanks to the side opening design. It is also nice to have that positive visual feedback that everything is in the proper position prior to drive-away.

The one disappointment is that the latch requires a lot of hand strength to operate. I am hoping that once installed that an application of WD-40 will overcome some of the friction in the mechanism. Time will tell. It is possible that I may have been happier with the high profile design for more leverage. Hard to know.


I recently sold a dump trailer that had a Bulldog 2 inch hitch on it. The new dump trailer I purchased is smaller but has a Chinese 2 5/16" hitch for some reason.
I really like the Bulldog style and since everything else I have is 2", I purchased this to replace the one that came on it.
As a self employed mechanic I have recommended my customer's use etrailer for supplies I use for them. They and I have always had a pleasant experience.
Thank you!

Sometimes, those shiny metal formed hitches can be difficult to on the ball without the latch getting in the way. And, maybe you think its locked down when it isnt. Thats why I cut those types off and install a cast iron Bull Dog. Simple to on and simple to secure. No guesswork.
KURT H - 06/11/2020


clearance light missing rubber grommet.
seems to be well made and easy to operate.
Fairlead is perfect for my trailer.

The coupler is still in use and performing as expected. I have used these couplers before and will continue to use them as they are quality and durable.
Larry R - 04/12/2019


Excellent Coupler with low price. I replaced the older Bulldog hitch with this one. The channels made it easy to weld it onto 3" channel iron. I prefer the low profile style, instead of the high profile model. I also purchased a lock from that goes through the hitch, replacing the normal clip that it comes with ( pn 28012). They also shipped me a 2" receiver hitch lock ( pn 7683) for my truck, and they keyed the two locks to the same key.


I think the Bull Dog hitches are far ahead of the compention.
I have relied on Bull Dog couplers for over 60 years , I am presently 85 years
I use BullDog exclusively, enough can go wrong when hauling horses, I
eliminate the trailer coming loose because of the Bull Dog hitch, whenever I
buy any tag along trailer I immediatly. change the hitch to a Bull Dog if
it has any other.
You can put me down as a VERY SATISFIED customer.


Great products and service from the items ordered, timely delivery thorough follow up to the excellent packaging. I’m a new trailer owner and will be using etrailer for the rest of my trailer needs!!


Great inventory and competitive pricing!


Replacement for worn out receiver on old trailer. Wish Bulldog were made in the USA, not Mexico. But, the others are made in China, which is even worse.

No problems. Remember to keep a hand on the lever when squeezing shut and let the slide close gradually so you dont pinch your other hand. I keep mine lubed with bicycle chain lube with Teflon. Also, i always grease the ball. Yes, that is messy but the metal-to-metal squealing is prevented and your coupler will last forever.

I replaced the hitch on one of my trailers with your bulldog . It is much safer than the old style hitch, I plan on replacing the hitches on all my trailers to your bulldog lok collar this spring.


This trailer hitch is heavy duty and works like a dream. The one that it replaced was cheaply made and did not hold up. We are a commercial business and don't have the luxury of tolerating bad equipment. The part arrived promptly and was exactly what was described on the website

So far so good. It has taken a beating and still working fine
Sunshine E - 07/06/2018


When it’s latched it feels a lot more secure than other types of hitches.


I have not installed this coupler although it is what I need.


Arrived promptly. Excellent service


Nice fit and finish. Just need to get the old one torched off, and this welded on. Much better than the stamped steel junk that came on the trailer.

Great product. No doubt now if the hitch is latched on the trailer ball or not.
David L - 11/13/2018


I order a Bulldog hitch and jack
it came as expected.
It will work great for my trailer.


Very good product, easy to install. Solved the problem of other hitches needing repaired constantly. This hitch is easy to use and locks securely.


Product very good. Only one problem, cant find a lock to go thru the safety hole while trailer not hooked up.

by: is all you need to know for ordering trailer supplies. Ordering was user friendly and entire order arrived ahead of schedule even though we chose ground shipping. All parts came "as advertised" products. Way to go!

  • Can the Hinged Ball Socket Mechanism On A Bulldog Trailer Coupler Be Repaired
    I absolutely do not recommend trying to repair your trailer coupler as this could be very dangerous to both you and others on the road. The hinged ball socket mechanism that is on your trailer coupler is not repairable. Therefore, your only option is to replace the entire coupler for which we have the Bulldog Collar-Lok Coupler part # BD028287 that uses a 2" hitch ball and has a 7,000 lb weight capacity.

  • Coupler Recommendation for Trailer to be Used when Loading Vehicles on Trailer
    As far as coupler style go I would go with a Collar Lok Bulldog part # BD028287 since the mechanism that holds the coupler to the ball is very sturdy and would be very unlikely to get damaged from the tongue weight pulling up when loading your trailer. Not saying a trigger latch would be an issue, but the Collar Lok just has a much larger clamp to spread out the weight of the trailer.

  • How Does Bulldog Collar-Lok Coupler w/ Low-Profile Latch # BD028287 Install on Trailer
    In order to ensure you get the full capacity of the Bulldog Collar-Lok Coupler w/ Low-Profile Latch # BD028287 you would need to have a qualified welder weld it on. We can't safely recommend bolting it on.

  • Is There a Bulldog Low-Profile Latch Replacement or Repair Kit Available
    I may have a solution for you, but unfortunately in this case you can't find one because these low profile latches are not available as a replacement part according to my contact at Horizon Global (who own Bulldog). If your latch has broken or is no longer working then you would need to replace the coupler and the # BD028287 would be the recommended replacement as it would be a like for like swap.

  • How to Get a Replacement Spring for a Bulldog Collar-Lok Coupler
    Your best option that I can provide for you would be to get the Bulldog High-Profile Latch Repair Kit # BD024200. This comes with the spring and a few other components that you might not need now-but could need in the future and would be nice to keep around as spares. We do not have the spring by itself so this would be the best option I could provide for you.

  • Compatibility of etrailer Coupler Lock on a 2-5/16 Inch Bulldog Coupler
    Good news, I can help you figure out if this coupler lock will fit your Bulldog coupler. As long as your pin diameter on the Bulldog coupler is larger than a 1/4 inch and the span is no bigger than 3-3/8 inches, then this coupler lock will work for you. I pulled the Bulldog coupler # BD028287 you had looked at from our warehouse and a similar style 2-5/16 inch # BD028499 and measured the size of the lock pin that goes in the coupler. It measured 5/16 inch diameter and a length of 2-3/4...

  • How Does Bulldog Collar-Lok Coupler # BD028287 Work Differently than Other Couplers
    Bulldog Collar-Lok Coupler # BD028287 and similar couplers have a sleeve that constantly puts pressure on the front of the coupler, the part that goes around the ball, so that it cannot come loose. There is also more surface area of the coupler making contact with the ball. Traditional couplers use what is essentially a wedge. The fit is predetermined and can me manually adjusted on some couplers by tightening or loosening a bolt or nut in the wedge/latch mechanism. This design can get...

  • Trailer Coupler Lock Compatible with Wide Coupler
    If you have a Bulldog Collar-Lok Coupler, then the EZ Lock Trailer Coupler Lock for 1-7/8", 2", 2-5/16" Bulldog Collar-Lok Couplers # BLTL-20-40D is your best option. If you want the pin style coupler lock, then the Bulldog Easy Access Coupler Lock - Swivel Head - Chrome # BD580409 is the largest span option at 3-5/8 inches.

  • Availability of a Locking Pin for the Bulldog Collar-Lok Coupler with Low Profile Latch
    Yes, I recommend the coupler lock # e98888 because it can replace the existing pin and it will fit inside the Bulldog Collar-Lok # BD028287. Just in case you don't have a lock for your hitch receiver, I recommend hitch receiver lock # e98880, that has an inside width of 2-5/8 inches for a 2 inch hitch. If you have a 2-1/2 inch hitch you can use the hitch receiver lock # e98881, that has an inside width of 3-1/16 inches. I included several video...

For your Bulldog coupler you would have to use the Trailer Coupler Lock, part # e98888. This is a coupler lock with an inside width of 3-3/8 inches.

  • Replacement for Atwood Yoke Style A-Frame Coupler For 2 Inch Hitch Ball
    Atwood was bought out and their replacement parts are no longer available - including the repair kit you mentioned - so the best option is to replace that A-frame coupler with a new one that attaches to a 2 inch hitch ball. There is a similar option with a yoke latch, the A-Frame Trailer Coupler # CA-5210-B, or another nice option with a low-profile latch is the Bulldog Collar-Lok Coupler with Low-Profile Latch # BD028287. Those are both weld-on options, but there is a bolt-on option...
