AL-KO Extended Neck Towball – 50 mm with Extended Neck

AL-KO Extended Neck Towball

The AL-KO Extended Neck Towball is a genuine 50 mm flange towball kit designed to work with AL-KO AKS stabilisers and coupling heads. Its extended machined neck gives extra clearance and articulation space required when using stabiliser hitches,  especially important for smooth, stable towing with caravans and trailers. 

Standard towballs often sit too close to the towbar for stabiliser hitches to function effectively — the deeper neck of this extended towball lets the stabiliser head move freely and reduces interference while turning, maneuvering or under load.

🧩 Why Use an Extended Neck Towball?

Standard towballs may not provide enough clearance or articulation space for stabilizer hitch systems — particularly when maneuvering on uneven terrain or tight turns. The AL-KO extended neck design pushes the ball further forward, improving space and helping stabilizer pads work correctly without binding or premature wear. This can lead to smoother towing and more reliable performance.
