    Whether you’re fabricating, upgrading or maintaining a trailer, Bulldog is the valuable source for heavy-duty couplers, rated from 5,000 to 15,000 lbs. GTW. (GTW=Gross Trailer weight, what your trailer weighs at the curb, loaded with tools, toys, food, beer, water, propane or whatever. It’s usually substantially more than the weight on the title.) The Bulldog hitch coupler fits both a-frame and round or straight tongues.

    Bulldog is a major supplier of Gooseneck hitches. Their line of under-bed goosenecks installs fast, without drilling or welding. Choose Bulldog hitches for trailer with hidden balls, or folding balls. The revolutionary BX1 Gooseneck Coupler has 50% more area in the coupler pocket, (making hooking up simpler), one hand operation, integral grease fittings and easily retrofits to conventional gooseneck trailers.

    Bulldog is among the best-known manufacturers of trailer jacks. They make square jacks, round jacks, worm gear jacks, bevel gear jacks, and 12V powered jacks. If you use a trailer more than a few times a year, a powered Bulldog trailer jack is a necessity. Or try one of their two-speed jacks, one that can shift gears to a much lower ratio when the jack is not just lowering or raising its foot, but actually carrying the weight of the trailer.

    Add in Bulldog’s line of hitch and coupler locks, and an extensive catalog full of jack accessories, and you’ll appreciate what other trailering pros have known for years: there’s no skimping on quality when you need a trailer part or accessory that gets used regularly instead of sitting in the yard more than not. Add a new addition to their product line: Max-Frame no-drill receiver hitches for your car or truck.

    Founded in 1919 in Wausau, WI above a car dealership by inventor Thomas J Jacob after an accident with a poorly-designed trailer hitch killed one of his prized hunting dogs, Bulldog is still in business. Several acquisitions later as part of Cequent Performance Products, Bulldog is still a leading manufacturer of high-quality Bulldog trailer hitches. With Cequent’s resources at their back, they promise to be in the same place after their second hundred years in business.

    Great Product.
    Fit without any problems. Was worried after I received the shipping estimate of a month away even though the website said they had 9 in stock. Had to call and they promptly contacted a different warehouse and it showed up in just a few days without any additional freight.
