The B&W Hitches GNXA4585 is a precision-fit gooseneck ball mount engineered specifically for the 2007 Toyota Tundra. Designed to install in the truck bed without cutting or drilling into the frame, this hitch delivers the reliable, heavy-duty towing performance that B&W is known for. If you need to pull a gooseneck trailer behind your Tundra, this is the purpose-built solution -- not a universal compromise.
B&W Hitches has built its reputation on tight-tolerance, vehicle-specific hitches that install cleanly and hold up under real working loads. The GNXA4585 is part of B&W's Turnoverball gooseneck hitch family -- a product line that pioneered the removable in-bed gooseneck ball concept and remains the benchmark for the category. When the ball is not in use, it folds below the truck bed surface and a cover plate snaps in to give you a smooth, usable truck bed.
Unlike generic or universal gooseneck adapters, the GNXA4585 is designed around the specific frame geometry of the 2007 Toyota Tundra. The mounting brackets align directly to existing frame attachment points, so installation is clean and the finished hitch sits level in the bed without shimming or modification.
The ball folds flush below the truck bed floor when not towing. A snap-in cover plate fills the hole for a clean bed surface -- no ball stub sticking up when hauling cargo.
Engineered exclusively for the 2007 Toyota Tundra frame. Brackets align to OEM attachment points for a secure, rattle-free installation with no drilling required.
B&W builds its gooseneck hitches from forged and heat-treated steel, not stamped plate. The result is a hitch that handles real working loads without flex or fatigue over time.
The gooseneck ball removes completely when not needed, giving full access to the truck bed for non-towing use. Re-installation is fast -- no tools required for the ball itself.
The GNXA4585 installs using the Tundra's existing frame access points. B&W supplies all necessary hardware. Most experienced DIY installers complete the job with basic hand tools in 1 to 2 hours. The crossmember and mounting rails drop into position under the truck bed, and the ball assembly threads into the installed socket from above.
Gooseneck trailers use a standard 2-5/16 inch ball mounted in the truck bed, located roughly over the rear axle. This configuration is common with livestock trailers, flatbed equipment trailers, and heavy-duty cargo trailers. If you are towing a 5th wheel RV or camper, you need a 5th wheel king pin hitch -- not a gooseneck ball mount. The GNXA4585 is a gooseneck product. Make sure your trailer coupler matches before ordering.
