Description
Overview:
This overrun coupling damper for AL-KO 251S couplings (MPN 764 093) is a direct replacement hydraulic unit designed to restore correct damping of the drawtube in braked trailer overrun systems. It controls and cushions the in/out movement of the coupling during braking and take‐up, reducing snatch and improving stability. Built for service in fleet and site environments, it is suitable for trailers and caravans fitted with an AL-KO 251S overrun head or housing. Typical applications include general duty trailers, plant and equipment transporters, car transporters and other braked trailers where an AL-KO 251S coupling is installed. Replacing a weak or failed damper helps maintain consistent braking performance and prevents excessive stress on linkage components, cables and brake shoes. This unit is supplied as a single replacement damper and is intended to fit in place of the original within the AL-KO 251S assembly, using the existing mounting hardware where serviceable.
Key Features:
- Direct replacement damper for AL-KO 251S overrun couplings
- Hydraulic damping action to control drawtube movement under braking and take‐up
- Durable steel construction for workshop and fleet use
- Mounting interfaces to suit the original AL-KO 251S positions within the coupling body
- Helps reduce brake snatch and improves trailer stability during deceleration
- Supplied as a single unit for service replacement
- Suitable for use across a range of braked trailer types using AL-KO 251S
Typical Applications:
Installed in the overrun coupling assembly on braked trailers and caravans fitted with the AL-KO 251S. Commonly used on general duty trailers, plant and machinery transporters, car transporter trailers and other commercial towing setups where the AL-KO 251S coupling is specified. Fits in place of the original damper inside the coupling to regulate drawtube travel and assist smooth braking engagement.
