I used the center section in an existing tube because the one on my trailer froze and broke. It fit perfect once I got the old one out. The grease zerk to fill the void and keep water out is a welcome addition. 460606

Ask the Experts about this Bulldog Gooseneck Trailer Coupler
Do you have a question about this Gooseneck Trailer Coupler?

  • Is there a 30,000 Pound Coupler Replacement Kit for Bulldog Gooseneck Coupler BD028900
  • I called Bulldog today to ask them about a coupler kit for the 30,000 pound square tube coupler. I assume the coupler you have is part # BD028900. If this is the case, the coupler kit, part # BD02877400 will indeed fit and will have the 30,000 pound capacity. The 20,000 pound capacity of the coupler kit is incorrect and will actually hold up to 30,000 pounds. The coupler kit is the exact same parts that are on the BD028900 coupler.

  • Is Bulldog Gooseneck Coupler Compatible with Temco Top Crank Adjustment Coupler?
  • It sounds like the Bulldog coupler # BD028900 may work for your application. This coupler adjusts 7 inches and uses an inner tube that is 4 inches fitting into an outer tube that is 4-1/2 inches. Without knowing the component of the Temco coupler, I can't confirm a fit, but if your outer tube is 4-1/2 inches, you should be able to make it work with minor adjustments because you will be doing a custom application.

  • What Size Ball Does the Bulldog Gooseneck Coupler Repair Kit # BD0287740300 Fit
  • Yes, the Bulldog Gooseneck Coupler Repair Kit # BD0287740300 that you referenced is designed to fit Bulldog gooseneck hitches like the # BD028900 that are all designed to fit 2-5/16 inch hitch balls.

  • Gooseneck Coupler to 5th Wheel Trailer Hitch Adapter Recommendation
  • You have some options in converting the gooseneck coupler on the trailer to be used with a 5th wheel trailer hitch. But, there is not an adpater that will replace the inner tube of the Bulldog Gooseneck Coupler, # BD028900. What you can do is replace the whole assembly, inner and outer tube, with Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter, # BD0289590300. This coupler fits the trailer the same as a gooseneck coupler with inner and outer tubes. It is adjustable. The only feature...

  • What Material is Bulldog Gooseneck Coupler Repair Kit Made Of?
  • The Bulldog Gooseneck Coupler Repair Kit # BD0287740300 uses steel parts. It is designed to be used with a number of Bulldog Gooseneck Couplers, each of which are also constructed from steel. The repair kit will work with Bulldog Gooseneck Coupler # BD028900, # BD0289600300, # BD0287690300 and # BD0287600300.

  • How Far Can I Extend Temco Gooseneck Coupler
  • Most inner tubes of gooseneck couplers have adjustability holes to allow you to pin the inner tube into the outer tube. From my research, the Temco gooseneck coupler inner tube has holes. You can extend to the last hole of the inner tube. If your Temco coupler has set screws or pinch screws instead of holes with a pin, most designs of gooseneck couplers allow for at least ten inches above the top hole on the inner tube according to Bulldog. To be safe, I would keep 10 inches or more...

  • Will a Blaylock EZ Lock for Set Screws on Gooseneck Couplers Fit a Square Bulldog Trailer Coupler
  • The Blaylock EZ Lock, # BLTL-51, should work fine with a square Bulldog gooseneck coupler like # BD0289800300, # BD0289600300, or # BD028900. Provided the coupler that you have uses set screws to hold the inner tube in place, this lock will prevent anyone from tampering with the set screws to release the inner tube. You could use # BLTL-53-40D2. This comes with the set screw lock, the coupler lock for the bottom of the coupler, and 2 padlocks.
