The AUGSMIAR GNXA4085 Gooseneck Ball Extender adds a 4-inch offset to your Turnoverball gooseneck hitch, increasing clearance and enhancing visibility for sharper turns and larger trailers. Built to endure demanding towing tasks, this extender pairs with your existing hitch to deliver extra maneuvering room when space is tight.

Premium construction and safety

  • Premium material: 3/4" thick high‑strength alloy steel, durable and corrosion‑resistant.
  • Heavy‑duty capacity: supports up to 20,000 lbs gross trailer weight (GTW) and 5,000 lbs vertical tongue weight (VTW).
  • Secure fit: designed to integrate with standard 2-5/16" ball hitches for a snug, reliable connection.
  • Safety tested: engineering and testing ensure towing stability under load.

Four-inch offset for improved maneuverability

The offset moves the trailer pivot point back, creating space between the gooseneck and the truck cab. This helps with visibility in tight turns and reduces the chance of contact on crowded or uneven roads.

  • 4" offset provides extra clearance during turning and reversing.
  • Improves line of sight to the trailer front for careful maneuvering.

Compatibility and easy installation

The GNXA4085 uses a standard 2-5/16" diameter ball and aligns with B&W Turnoverball gooseneck hitches, with the exception of Dodge Ram 1500 (2009–2015) and Toyota Tundra (2007–2015). It mirrors the original part size, enabling a quick swap and minimal downtime. The bottom of the shank sits 2 inches from the pin hole, a detail that helps plan installation.

Real-world use scenarios

Designed for owners towing heavy trailers, livestock trailers, or long flatbeds where space near the cab is tight. The added clearance can help maintain control on rural highways, navigate tight city streets, and improve overall towing confidence on challenging routes.
