3244 Kingpin Coupler Block for Andersen Ultimate 5th Wheel

This 3244 kingpin coupler block is a precision-engineered direct replacement for your Andersen Ultimate 5th Wheel Connection system. Unlike generic plastic replacements, our block is manufactured from high-strength nylon PA66 with glass fiber reinforcement — the same category of engineering material used in original equipment manufacturing for trailer and RV components. The UV-stabilized formulation resists sun exposure and temperature cycling, preventing the brittleness and cracking that can occur with standard plastic parts over time. The block is designed to clamp tightly to a standard 2-inch trailer kingpin on the pin box and couple to a typical 2-5/16 inch gooseneck ball on the hitch base, maintaining the same connection ball interface as the original unit. Installation takes about 5 minutes — no specialized equipment, no permanent modifications to your trailer. The snug-fit design eliminates play and vibration, ensuring the gooseneck ball stays positioned correctly during towing. Whether you are a weekend RVer replacing a worn coupler block or maintaining a fleet of towing vehicles, this replacement delivers the right balance of durability, weight savings, and value. Every unit is individually inspected before packaging. Compatible with all Andersen Ultimate 5th Wheel Connection systems using part number 3244.

• Engineering-Grade Nylon Composite — Manufactured from high-strength nylon PA66 with glass fiber reinforcement, not cheap generic plastic.

• Precision Snug Fit Design — The coupler block is engineered to exact OEM tolerances for a tight, secure connection that eliminates play and vibration during towing.
