LAMGENIE 3244 Kingpin Coupler Block – OEM Replacement

Upgrade your Andersen Ultimate 5th Wheel Connection system with this LAMGENIE 3244 Kingpin Coupler Block, a direct OEM replacement engineered for precision and durability. Unlike generic plastic alternatives, this coupler block is crafted from high-strength nylon PA66 with glass fiber reinforcement—the same premium material used in original equipment manufacturing for trailer and RV components. The UV-stabilized formulation ensures long-lasting resistance to sun exposure, preventing degradation and brittleness over time, so you can tow with confidence season after season.

Designed as a drop-in replacement for Andersen Ultimate hitch systems, this coupler block delivers a perfect fit for your 2″ trailer kingpin and 2-5/16″ gooseneck ball, maintaining the same secure connection as the factory unit. The precision-molded design eliminates play and vibration, ensuring a rattle-free towing experience while holding the gooseneck ball in place. Installation is quick and tool-free—simply remove the shifter panel, replace the old block, and reassemble with the included hardware. Weighing significantly less than metal alternatives, this lightweight yet robust coupler block maintains full load capacity while reducing strain on your hitch system. Whether you're upgrading your 5th wheel accessories or repairing a worn-out component, this essential part is a reliable choice for any Andersen-compatible setup.
