Heavy-duty 4" offset gooseneck ball extender designed to add clearance and restore proper fit for B&W Turnoverball hitches while supporting up to 20,000 lbs GTW and 5,000 lbs VTW.

This AUGSMIAR GNXA4085 gooseneck ball extender is a beefy replacement/upgrade part engineered to move the trailer pivot point 4 inches rearward. Constructed from 3/4" high-intensity alloy steel and finished for corrosion resistance, it matches the standard 2-5/16" ball diameter and the factory shank geometry so it installs like the original. The extender is intended for B&W Turnoverball-style gooseneck hitches (with noted vehicle exceptions), giving added cab clearance and improved visibility for tight turns without changing coupler or trailer components.

How does this extender create more cab clearance and why does that matter?

Shifting the ball 4 inches rearward increases the distance between the trailer nose and the truck cab during extreme articulation. That extra space reduces the chance of contact on sharp turns and provides better sightlines while backing or cornering.

  • 4" offset repositions trailer pivot point behind factory location
  • Improves visibility and reduces trailer-to-cab contact risk
  • Helpful when using extended-bed accessories or thicker rear bumpers

Will this fit my B&W Turnoverball hitch and standard gooseneck setup?

The GNXA4085 uses a 2-5/16" ball diameter and a 2" distance from the shank bottom to the pin hole to match typical Turnoverball geometry. It is designed to fit most B&W Turnoverball systems, but some trucks are excluded—always verify vehicle compatibility before purchase.

  • Standard 2-5/16" ball diameter for common couplers
  • 2" shank-bottom-to-pin-hole dimension matches OEM parts
  • Not compatible with Dodge Ram 1500 (2009–2015) or Toyota Tundra (2007–2015)

What strength and durability can I expect from this extender?

Manufactured from 3/4" high-intensity alloy steel, this extender is built for demanding towing loads and resistance to corrosion. It has been rated for a gross trailer weight (GTW) of 20,000 lbs and a vertical tongue weight (VTW) of 5,000 lbs when used as specified.

  • 3/4" thick alloy steel construction for high tensile strength
  • Rust- and corrosion-resistant finish for longer service life
  • Tested and rated to 20,000 lbs GTW and 5,000 lbs VTW

How easy is installation and are special tools required?

Installation mirrors the original turnoverball attachment: remove the factory ball and replace it with the AUGSMIAR extender using the same pin and retaining hardware. No special modifications are required, making it a straightforward swap for most owners.

  • Direct-fit sizing like OEM gooseneck balls for quick replacement
  • No permanent modifications or welding needed
  • Typical hand tools and a torque wrench recommended for safe installation

Who is this for: The AUGSMIAR GNXA4085 is aimed at truck owners who tow gooseneck trailers and need extra cab clearance, better turning visibility, or a rugged, OEM-style replacement ball. It’s a practical choice for ranchers, commercial haulers, RV movers, and anyone using a B&W Turnoverball hitch who wants a heavy-duty, corrosion-resistant 4" offset solution. Always confirm compatibility with your specific truck and hitch model before installing.
