With the Defender gooseneck coupler from B&W, you get the best of both worlds. Not only does this coupler make hookup an absolute snap, but it also defends against trailer theft. The built-in lock can be engaged when your trailer is hooked up to your truck, thus preventing uncoupling. It can also be locked when your trailer is not hooked up, preventing would-be thieves from hooking your trailer up to their gooseneck ball.


B&W Defender Locking Gooseneck Coupler

To begin the process of hooking up your trailer, unlock the Defender. Line the hitch ball in your truck up with the coupler. Because the funnel on the Defender is larger than the average gooseneck coupler funnel, you don't have to be exact when lining your tow vehicle up with your trailer. Just make sure that the ball is within 2" of the coupler's socket.


B&W Defender Gooseneck Coupler Oversize Funnel

Once you have the ball lined up with the coupler, lower your trailer. The funnel will guide the ball into the socket, and the ball latch will engage automatically. You will know that the latch is engaged because the handle will rotate counterclockwise and retract against the coupler's housing. When you confirm that the Defender is properly latched around your hitch ball, simply push the lock cylinder in. When locked, the cylinder will be flush with the coupler's housing.

Video Transcript for B and W Gooseneck Trailer Coupler - Coupler with Inner Tube Only - BWGNC4250 Review

Today we're going to review part number BWGNC4250, this is the BMW defender locking goose neck coupler base assembly. It is round and it has a 25,000 pound weight capacity. Now this steady 00:00:16 inner tube is designed to pair with your existing outer tube to help create an adjustable goose neck coupler for hooking your trailer up to your truck. On the very bottom here it uses a comb shaped funnel which we'll make it very easy to guide the ball into the socket. Basically if your goose neck ball like this is within two inches of this, the comb would actually slide it into and guide it into, the ball into the socket.Now it does have this automatic latching mechanism right here for super simple hookup. Basically you just pull this handle out, rotate it up to open the coupler and then you line your hitch ball up with this coupler and then lower the trailer and the internal latch will automatically engage around the ball and lock it into place.

Then right over here on this side you can see there's actually a locking cylinder that you can just push in and turn the key a quarter of a turn pull it out and it will lock that handle so it gives you excellent security to keep anybody from messing with unlatching your goose neck.There are two keys that are included, comes with it and we'll just put the key in here to unlock it. There we go, got it unlocked. This is made of a inaudible 00:01:34 steel construction, has a very heavy wall tubing which will exceed industry standards. Has a nice black powder coat finish which is corrosion resistant and the part is made in the USA. Now this is designed to fit on the goose neck ball size of two and five 16s and if youll notice theres a pin right here and a clip and theres actually about six holes.

That six holes will actually give you 11 inch range of vertical adjustment if I measure from center to center from the bottom hole to the top hole. Its 11 inch range of vertical adjustment when hooking this up to your existing outer tube.The two diameter, the outside diameter of this is four inches. Again weight capacity is 25,000 pounds, has a vertical low limit of pin weight capacity of 7500 pounds and this does come with a limited one year warranty. Just going to put the pin back in here but I do want to give you an idea of how this coupler will work on a goose neck ball. Ill go ahead and put the clip back on there, there we go.

What Im going to do is basically move this just to the end where we can get a goose neck ball under it just like that. Now Ive got the lock open and if I pull the handle out and raise it up, that means that latch underneath is open. Heres an example of two and five 16 goose neck ball that might be in your truck.Basically if you just get close, you can see that right out here if you hit it its actually going to pull the ball underneath because its a comb shaped funnel. When it pulls the ball underneath, it will actually move up there and boom you can see it will lock right onto the goose neck ball and then all you have to do is push this in, turn it a quarter of a turn and its all locked into place. Youre locked on the goose neck ball.

To get it off just unlock it and if you pull this and release it, you can see the goose neck ball comes right out. Very nice, simple feature when hooking up to your goose neck trailer to your truck. That should do it for the review on part number BWGNC4250, the BMW defender locking goose neck coupler base assembly. .

  • 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...

  • Replacement Inner Tube For B&W Gooseneck With Lock Included
  • I recommend the B&W Defender Locking Gooseneck Coupler Base Assembly, part # BWGNC4250 for your trailer. This is the inner tube with the base that will work with the outer tube. This inner tube has a built-in lock and has 2 keys included. The tube diameter is 4 inches and it has a weight capacity of 25,000-lbs.

  • How Does the B and W Defender Gooseneck Hitch Install on a Trailer
  • As long as you have an outer tube installed on your gooseneck trailer that is designed to fit an inner tube with a 4 inch diameter the # BWGNC4250 would install pretty easily on your trailer. If not, then you would want the # BWGNC4251 instead as this comes with the outer tube that would get welded to your trailer by a qualified welder. If you didn't want any adjustability with your gooseneck coupler you could always weld the # BWGNC4250 directly to your trailer. Also, the claim...

  • Replacement Inner Tube Recommendation for Bulldog Gooseneck Coupler that Uses Set Screws
  • I believe what you are looking for is actually the part # BD0287690300. This coupler tube is 4-1/2 inches in overall diameter and is designed to have set screws secure it in place to the outer tube. I can't recommend the B and W you mentioned for that.

  • Replacement Inner Tube for Gooseneck Hitch in 2011 Chevrolet Silverado 3500 with 6-1/2-Foot Bed
  • The linked page will show you both round and square gooseneck inner tubes. I measured two of the round tube parts, # BD0287610300 from Bulldog and part # BWGNC4250 from B&W, and both have an overall length of 28-1/4-inches and an outer diameter of 4-inches. Please let me know your gooseneck hitch brand, weight rating and tube shape. I will be glad to check all available items for one with your required length of more than 31-inches.
