B&W HitchesGooseneck Ball Mount2007 Toyota Tundra SpecificB&W Hitches GNXA4585 -- Gooseneck Hitch for 2007 Toyota Tundra

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.

Purpose-Built Gooseneck Towing for the 2007 Toyota Tundra

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.

Turnoverball Design

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.

Vehicle-Specific Fit

Engineered exclusively for the 2007 Toyota Tundra frame. Brackets align to OEM attachment points for a secure, rattle-free installation with no drilling required.

Forged Steel Construction

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.

Removable Ball

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.

Installation Overview

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.

No Bed Liner Cutting Required for Standard Install: The socket opening is sized to work with most factory and aftermarket bed liners -- a small relief cut in the liner mat is all that is needed in most cases, not a full cutout.

Gooseneck vs. 5th Wheel Towing

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.

Gooseneck Trailer Compatibility: This hitch accepts standard gooseneck couplers designed for a 2-5/16 inch ball. It is not compatible with 5th wheel trailer king pins unless a gooseneck-to-5th-wheel adapter is added separately.

What's in the Box

  • Gooseneck ball and socket assembly
  • Under-bed mounting crossmember and rails (vehicle-specific)
  • All mounting hardware (bolts, washers, nuts)
  • Bed cover plate for when ball is removed
  • Installation instructions
Heads Up -- Confirm Your Model Year: The GNXA4585 is designed for the 2007 Toyota Tundra specifically. Toyota introduced a redesigned Tundra platform in 2007. This hitch does NOT fit earlier Tundra models (2000-2006) or later model years without verifying part number compatibility. Double-check your year before ordering.
Torque and Inspection Tips: After installation, re-torque all fasteners after the first 500 miles of towing. Inspect the socket and ball threads periodically and apply a light coating of grease to the ball shank threads to prevent galling. Keep the cover plate in place whenever the ball is removed to prevent debris from entering the socket.

Important Information
  • This hitch is designed ONLY for the 2007 Toyota Tundra. It will not fit earlier (2000-2006) or later Tundra models without separate verification of part compatibility.
  • This is a gooseneck ball mount -- it is NOT compatible with 5th wheel trailer king pins. Confirm your trailer type before purchasing.
  • Always verify your truck's towing capacity in the owner's manual before hooking up any trailer. The hitch does not increase your vehicle's rated tow capacity.
  • Re-torque all mounting hardware after the first 500 miles of towing. Loose fasteners under load are a serious safety hazard.
  • Do not exceed the rated capacity of the hitch or your vehicle's GVWR and tow ratings -- whichever is lower governs safe operation.
  • Inspect the ball, socket, and all fasteners before each towing season or every 5,000 miles of towing use.
