  • Square Tube
  • Bulldog
  • Coupler with Inner Tube Only
  • 25000 lbs GTW
  • 2-5/16 Inch Gooseneck Ball
  • Manual Latch

Short base assembly is made of durable steel. Large bottom locking plate makes hookup fast and easy. Ball pocket provides tight fit with less rattle. Pair with existing outer tube for a secure, easy-to-use gooseneck coupler.


Features:

  • Sturdy, short inner tube pairs with existing outer tube to create adjustable gooseneck coupler
  • Oversize funnel makes it easy to guide ball into socket
    • Bottom locking plate is 50 percent larger than competition
    • Coupler engages even if you miss the ball by just over an inch
  • Tight ball fit helps to reduce jarring and rattling
    • Ball pocket provides contact on both sides of ball
  • One-handed operation with easy-to-use handle
    • Lockable with padlock (sold separately)
    • Oil-impregnated bushings increase life of locking mechanism
  • Smooth operation over time
    • Integrated grease fittings throughout make for simple maintenance
  • Superior, high-strength steel construction

  • Ball size: 2-5/16"
  • Tube outer width: 4"
  • Range of vertical adjustment (when used with outer tube): 8"
  • Overall length: 22-1/2"
  • Weight capacity: 25,000 lbs
  • Vertical load limit: 7,500 lbs
  • Theft-deterrent locking hole diameter: 5/16"
  • Limited 5-year warranty


The BX1 gooseneck coupler from Bulldog is designed to provide the easiest, most secure hookup possible. The bottom locking plate on this coupler is 50 percent larger than the competition, providing additional surface area to guide the ball into the socket. Miss the target by just over an inch and the coupler will still engage.


Bulldog BX1 Gooseneck Coupler Locking Plate

Once hookup is complete, use the easy-to-access, easy-to-maneuver handle to lock the coupler to the ball. When the handle is down, you know that everything is secure and it's okay to tow. For extra security you can insert a padlock (sold separately) through the fixed plate.


Once you begin towing, you may notice that there is far less rattle and jarring at the coupled point than you'd experience with a standard gooseneck coupler. This is because the ball pocket on the BX1 provides contact on both sides of the hitch ball, rather than on only one side, which is typical of the competition. The result is a tight fit around the ball that makes for a smoother, quieter and more secure towing experience.

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

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

Really like this unit, it was not difficult to install, it was a direct replacement for our 30 year old stock trailer, and it is so easy to use my wife agrees this was a best buy for us. 675413

This is a well made product that fits and works as billed. I added a coat of paint to match my trailer, did the installation and have pulled that trailer 10,000 miles since. Be sure to lubricate the locking mechanism well and regularly to prevent it from being very difficult to use. 611246

Julie at etrailer got me just what we needed and got it here in time for the move! We were replacing an older goose neck coupler that had become damaged. Although a original replacement wasn’t available Julie found a newer model that would fit and worked out perfect! Super easy to hook up the trailer with this new BX1 coupler!! Thanks!! 527920

Needed a gooseneck inner tube because the trailer I purchased had a 5th wheel setup. I removed the inner tube for the 5th wheel and installed the gooseneck inner tube. Everything worked very well. Thanks. 393008

Hitch fit excellent but the latch mechanism had to be shimmed to get it to properly tighten against the ball. After I made and installed the shims it works great and trailer pulls much smoother. 277922

I ordered this hitch tube on Monday and it arrived on Friday of the same week I was amazed at the very quick turn around. When it arrived I found that it was heavier duty than the one I replaced. Ian completely satisfied with etrailer and the part they sent. 232430

Got just what is ordered, A bit spectical about the Cast locking mechanism, concerned with durability. Like the concave bottom for the dummies that can't back up right. 174938
