Video Transcript for Bulldog Gooseneck Trailer Coupler - Coupler with Inner Tube Only - BD1289050300 Review

Today we're going to be reviewing part number Bd1289050300. This is the Bulldog BX1 Gooseneck Coupler. It is the Inner Tube. This sturdy inner tube is going to pair with the existing outer tube to create an adjustable Gooseneck coupler. It's going to feature the oversize funnel, it's going to make it easy to guide the ball into the socket. It's going to be this portion here. The bottom locking plate is 50 percent larger than competitions.

The coupler's going to engage even if you miss the ball by just over an inch. It has that nice funnel, it's going to help direct the ball into the coupler. The tight ball fit is going to help to reduce jarring and rattling. The ball pocket is going to provide contact on both sides of the ball. It's going to feature the one-hand operation so it's going to be very easy-to-use, especially using the handle. This portion is going to be lockable using a padlock.

It's going to feature the oil bushings, its going to increase the life of the locking mechanism. You can see here, by turning the handle, that's going to allow you to adjust the plate as needed. That way you can engage or disconnect the ball from the coupler. It's also going to provide smooth operation over time. It's got the integrated grease fittings throughout that are going to make for simple maintenance. It's got the superior, unfinished high-strength steel construction so it's going to provide a really long life. It is designed to fit a 2-5/16" ball.

The tube diameter measuring the outside to outside is going to give us a measurement of 4". The range of vertical adjustment when used with the outer tube is going to be 8". If you need the outer tube, you can find that here at etrailer.com using part number Bd0289500300. It's going to give us an overall length of 22", with a weight capacity of 30,000 lbs. It also has the zert fitting right here, that way you can get the grease as needed. Again, easy maintenance and it's going to provide a really long life.

It's going to come with a pin and clip. The clip is attached to the pin with a cable, that way you don't ever have to worry about misplacing it or losing it. Then again, you have the adjustment holes as well, allowing for 8" vertical adjustment when used with the outer tube. That's going to do it for today's review of part number Bd1289050300. This is the Bulldog BX1 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

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

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

Wish this coupler had come on the trailer when it was built. It is easy to hook up and lock. Really like the grease fitting, it keep the coupler loose and also keeps the ball lubricated. 736627

I bought a dump trailer that had a 5th coupler on it. Switch to a gooseneck for the weight capacity and this has been a great coupler. Easy to use and holds tight. Pulled a lot of weight with it with no problems or damage. Would buy again if I needed one. 633847


Comments
Coupler is still working great. Has some surface rust around the latch area since I did not paint it there. All and all still works good as new.
