Purchased this replacement for the original coupler. I had to cut the tube to the correct length on my older enclosed Featherlite gooseneck. The coupling operation is easier and I love the beveled/centering coupler which makes it much easier to center the ball while lowering the trailer. Excellent newer designed product from Bull Dog! 646383

Great Product and very pleased with it. Only thing that had to be done was cut 3 inches off the tube so that the Hart trailer would sit level on the the Freightliner. Also very pleased with how quickly everything got shipped and was delivered. Thanks Again!! I will recommend this product to anyone and how easy it is to hook up and the design of the coupling and latch. 582907

I replaced my old bulldog coupler with the newer BX1 coupler, it's so much nicer and easier to lock/unlock. I've not actually used it yet, I did locked the ball in the coupler on my original and the BX1 to compare and it was a much tighter fit. I can tell I'm going to love it - can't wait to pull my bobcat, I'm sure it's going to be a smooth ride. 324986


Comments
Just hauled my bobcat 325 miles and my BX1 coupler did and awesome job! No worries pulling with this coupler...it’s so much safer than my old one.

Great, well built product and support. I had several questions about this product and someone from their technical support team promptly responded multiple times until all of my questions had been answered. By far the best bang for the $$$. It would have been nice if it had come pre-painted or at least primed but the decals had peel off covers so you could simply paint it the color of your choice and then peel off the covers and it looks great. Very well built and sturdy product. Can't ask for more. 227654

Review from a similar BX1 in Gooseneck Coupler


There is not a locking load bearing pin manufactured to Bulldog's knowledge that fits these types of tubes. People usually steal the trailer and not the tube (unfortunately for me the idiots stole my tube and not the trailer). Standard coupler locks are 1/4" shank usually, and the end of the load bearing pin has a .20" hole for the retainer pin. Bulldog sees no reason why it couldn't be drilled out to support a 1/4" coupler lock that will fit on the end of the 3/4" diameter load bearing pin. I have not yet performed this modification of the load bearing pin, but will upload pics once complete. 455175

Review from a similar BX1 in Gooseneck Coupler


This gooseneck hitch is exactly what I was looking for. It fit right into the existing neck on my horse trailer. The latching mechanism is great! I can now hook and unhook my trailer by reaching into the bed without having to actually climb up onto the truck. 378490

Review from a similar BX1 in Gooseneck Coupler


Replaced my old one with this on my 20k GN as it was getting hard to unlatch. This one also helps with hooking up with the large opening and you can lock it with a padalock. The latch design is easier than the old style and easy to tell if it is latched or not. 365487

Review from a similar BX1 in Gooseneck Coupler


Would not have been able to use trailer without it truck was to tall. Tons of misalignment is allowed for hooking up. If etrailer was smart they would sell the pin to lock the latch with the receiver. Can't use standard hardware because clearance is tight. Has to be the correct oddball Lynch pin. If they do sell it, make it like other sites 'customers frequently bought with this...' 436956

Review from a similar BX1 in Gooseneck Coupler


Pretty good product, dimensions are as described. I bought it for the low profile, it will let us get a few more inches of height out of our gooseneck connection. Shipped and delivered on time, which is always appreciated. Be aware, this is shipped unpainted. I will spray paint mine to keep it from rusting. Haven't put it into use yet, I will update my review when I put it on the gooseneck. 801786

Ask the Experts about this Bulldog Gooseneck Coupler

  • Will Bulldog BX1 Gooseneck Coupler Inner Tube Fit 1989 4-Star Gooseneck Horse Trailer
    Yes, you can use the Bulldog BX1 Gooseneck Coupler Inner Tube # BD1289020300 for your application but you will need to drill out a hole going through your outer tube for the pin. I confirmed this with my contact at Bulldog and I have attached a clip from the installation instructions for you to check out. If you would rather not go this route then the only other option we have for an inner tube with a 4" diameter that doesn't require the use for a pin going all the way through is the...

  • Overall Length of the Bulldog BX1 Gooseneck Coupler part # BD1289020300
    I went out into our warehouse to measure a Bulldog BX1 Gooseneck Coupler part # BD1289020300 that we have in stock and found that it measures 28-1/2 inches in length.

  • Recommended Bulldog Gooseneck Coupler Inner Tube
    If you are just needing the inner tube for your Bulldog Gooseneck Coupler, I recommend looking at the Bulldog BX1 Inner Tube # BD1289020300. This base assembly is made of durable steel and features large bottom locking plates for fast and easy hookup. It has the same 25,000 pound weight capacity as the full assembly you were looking at and is designed for a 2-5/16 inch ball size. The tube's outer diameter is 4 inches and its overall length is 28-1/2 inches. The range of vertical adjustment...

  • Could Bulldog BX1 Gooseneck Coupler Fit 1989 4 Star Gooseneck Horse Trailer
    The Bulldog BX1 Gooseneck Coupler Inner Tube # BD1289020300 that you referenced has an outer diameter of 4 inches and is designed to fit the standard size of 4 inch outer gooseneck tubes. If that's what you trailer has this will fit and work well. The pin hole that secures the tube is 3/4 inch in diameter which your outer tube will need to have as well.

  • Height Adjustment Hole Spacing on Bulldog BD1289020300 Gooseneck Coupler
    The linked photo of the Bulldog BX1 Gooseneck Coupler Inner Tube # BD1289020300 shows the four vertical holes that allow for 8-inches of height adjustment. My contact at Bulldog advised that the top hole's center is 18-iches up from the top of the coupler. The hole centers are spaced apart 2.6-inches.

  • Recommended 5/8 Inch Locking Pin For Bulldog Gooseneck Adapter
    The Bulldog Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # BD580412 should work for this application. The usable pin length is 4 inches and that is the outer diameter dimension of the BullDog Gooseneck # BD1289020300 outer tube diameter.

  • Recommended Lockable Gooseneck Coupler Inner Tube And Padlock
    Yes, the Bulldog BX1 Gooseneck Coupler Inner Tube - Round - 2-5/16" Ball - 25,000 lbs # BD1289020300 is lockable with a standard padlock. I recommend the Master Lock Laminated Steel Padlock- 1-9/16" Wide- 3/8" Shackle - Blue Cover - Keyed Alike # ML312KA for a little less metal on metal rattle.

  • Gooseneck Coupler That is Needed Longer Than 22 inches
    We do have some options available that are a bit longer than the Bulldog BX1 Gooseneck Coupler Inner Tube # BD1289050300. The Bulldog BX1 Gooseneck Coupler Inner Tube # BD1289020300 has the same diameter and hitch ball spec and it has an overall length of 28.5" which is 6.5" more than the part you were looking at. The only problem is that it is only rated for 25,000 lbs. If you are needing the 30,000-lb weight capacity rating then you can go with the Convert-A-Ball Multi-Cushioned...

  • Safety Chain Recommendation for Use with Bulldog Coupler 1289020300
    For a general-purpose safety chain for a standard gooseneck coupler like the Bulldog part # BD1289020300 we offer # FCHA0050324 from Fulton. This is a 42-inch Grade 70 chain with 5/16-inch clevis. This is sold as a single chain, not a pair. Most people will weld the chain to the trailer or some will bolt it on. The part # AM3109 is designed for use on a Ranch Hitch adapter and was not intended for use on standard couplers.
