The Robot Weld

A close look at the robotic welding cells that lay down the structural welds on B&W hitches, and the people who program and check them. Consistent welds are what capacity ratings depend on, and this is how B&W makes sure every weld is the same as the one that passed the test lab.

Set Your Mirrors For Towing

B&W's quick guide to setting truck mirrors for a trailer: what you need to see, where the blind spots move, and when extended mirrors earn their keep. A thirty-second adjustment before you pull out makes every mile after it safer.

Safety Chains Done Right

B&W's guide to trailer safety chains: how to size them, how to cross them under the coupler, and how much slack is right. Two minutes here is the cheapest insurance in towing, and it applies to every trailer this product will ever pull.

Frequently Asked Questions

Straight answers on specs, fit and support

Does this fit my truck?

It is not a truck part. The Extend-A-Goose fits into your trailer's gooseneck tube and moves the coupler back, so what it has to match is the trailer: a standard 4" inner diameter round tube. Any truck with a suitable gooseneck ball can then pull it.

How much clearance does it give me?

It offsets the coupler by 10". Whether that solves your problem depends on your bed length and how sharply you need to turn, so the honest test is to fit it, couple up empty and swing the truck through your worst turn while somebody watches the cab. Do that in a yard, not in a fuel island.

What is it rated for?

24,000 lb gross trailer weight and 6,000 lb vertical tow weight. Those are the extension's own figures. If your trailer is rated higher than that, fitting this caps you at these numbers, so check before you buy.

Will it fit square tubing?

No. It is made for standard 4" inner diameter round trailer tubes. Measure yours before ordering; square gooseneck tubing is common enough that it is worth thirty seconds with a tape.

Is installation something I can do myself?

It is within reach of a competent home mechanic, but treat it seriously: this is the structural connection between your trailer and your truck. Support the gooseneck, follow B&W's instruction sheet exactly, and test it empty before you load the trailer.

Can I lock it?

Yes, the coupler accommodates a padlock. That is worth using on a trailer that spends time parked somewhere other than behind a locked gate.

Great product!

This is my second B&W Gooseneck Hitch Extender. I use them on gooseneck horse trailers with short bed truck. I installed it myself, really easily. Gives me great clearance with having a tool box in the bed!
