Description
Overview:
This AL-KO pressed delta overrun brake coupling assembly (MPN 764 165) is a complete bolt-on unit for braked trailers built on AL-KO pressed steel delta A-frames. It combines an inertia overrun device with a 50mm (approx. 2 in) coupling head to control and transmit braking force to the trailer's brake system under deceleration. Built around a robust pressed steel body, it is specified for trailers up to 2700kg gross trailer weight (2.7 tonnes, approx. 5,952 lb), making it suitable for medium to heavy-duty towing in plant hire, construction and transport applications. Supplied as an assembled coupling with head, it is designed to replace a worn or damaged overrun unit on compatible AL-KO pressed delta drawbars, restoring smooth braking performance and positive engagement on a standard 50mm towball. This assembly is a trade-standard fitment across a wide range of professional trailers where the AL-KO pressed delta pattern is used.
Key Features:
- Overrun brake coupling assembly for braked trailers
- Rated to 2700kg GTW (2.7 tonnes; approx. 5,952 lb)
- Suits standard 50mm towball (approx. 2 in)
- For AL-KO pressed steel delta A-frame mounting
- Pressed steel construction for strength and durability
- Inertia (overrun) actuation for progressive braking
- Supplied as a pre-assembled unit with coupling head
- OEM cross-reference: AL-KO overrun device 251S with AK270 head
Typical Applications:
Used on braked trailers built with AL-KO pressed steel delta drawbars, including plant and machinery trailers, car transporters, general-purpose and box trailers. Suitable as a service replacement where the original fitment is the AL-KO 251S overrun device paired with an AK270 50mm coupling head, or where an equivalent AL-KO pressed delta pattern assembly is required.
