The Humbaur 15000017 is an original AL-KO AKS 3004 safety coupling, specifically designed for trailers with a total weight capacity of up to 3000 kg. This coupling significantly improves driving stability and safety by effectively suppressing snaking movements and pitching. It features a wear indicator for the friction pads and the coupling mechanism, ensuring optimal performance and timely maintenance. The AKS 3004 is equipped with four friction pads that apply pressure to the trailer's towball, providing superior damping. This genuine Humbaur part ensures reliable and secure trailer attachment.
