How the King Pin Coupler Assembly Works

The rectangular king pin coupler assembly mounts to your trailer’s king pin and interfaces directly with the Andersen Ultimate 5th Wheel Connection base. The integrated funnel helps guide the hitch connection into place, making alignment easier during hookup.

When installed properly, the king pin coupler ensures secure vertical load transfer and stable articulation during towing. Replacing a worn or damaged coupler assembly restores correct hitch function and helps maintain predictable, controlled towing performance.

Because this is the rectangular version, it is designed specifically for compatible Ultimate Connection configurations that use this coupler style.
