Product Description

AL-KO 251G overrun device with AK301 hitch for 3000 kg trailer with V-type drawbar

The AL-KO 251G Overrun Brake System is engineered for braked trailers with V-type drawbars, supporting a total weight range of 1550kg to 3000kg. Featuring the AK301 Ball Hitch made of durable cast iron, it ensures a secure and stable connection to the towing vehicle, even under heavy loads. The system's hot-dip galvanized steel housing offers advanced corrosion resistance, protecting against rust, road salt, and mechanical wear for long-term durability in harsh conditions.

This device automatically synchronizes the trailer's brakes with the towing vehicle, reducing stopping distances, stabilizing movement, and minimizing wear on the vehicle's braking system. Its three-range return lever simplifies operation and adjustment, while dual mounting options (top or bottom of the drawbar) provide flexibility for diverse trailer designs. Safety is prioritized with a hitch wear indicator, correct coupling sensor, and anti-disengagement lock to prevent accidental uncoupling. Compatible with AL-KO 1637/2051 braking mechanisms, it ensures seamless integration and reliable performance.
