Description
Overview:
This overrun coupling damper (MPN 764 099) is a replacement damper unit for AL-KO 90S/2 and 90S/3 overrun devices used on braked trailers. It controls the movement of the drawbar under braking, providing a smooth, progressive action that helps prevent snatch and reduces shock loading through the towing setup. Worn dampers can lead to harsh or inconsistent braking and coupling "nodding"; replacing the damper restores correct overrun function and improves stability during deceleration and low‐speed manoeuvring. Designed for routine service replacement, it fits within the overrun assembly on the A‐frame and works with the existing coupling and brake linkage. Typical applications include general duty trailers, plant and equipment transporters, car transporters and caravans fitted with the relevant AL-KO 90S/2 or 90S/3 couplings. Cross‐reference: AL‐KO 359987 (for identification only).
Key Features:
- Direct replacement damper for AL-KO 90S/2 and 90S/3 overrun couplings
- Restores smooth, progressive overrun braking action
- Helps reduce snatch and shock loading during braking and manoeuvring
- Fits within the drawbar/overrun device on A‐frame trailer chassis
- Suitable for a wide range of braked trailers using 90S/2 or 90S/3 couplings
- OEM cross‐reference: AL‐KO 359987 (equivalent reference)
- Service part for maintaining coupling performance and braking consistency
- Designed for straightforward replacement during scheduled maintenance
Typical Applications:
Used inside the overrun device on braked trailers equipped with AL-KO 90S/2 or 90S/3 couplings, including general-purpose trailers, plant and machinery transporters, car transporters and caravans. Fitment is specific to the AL-KO 90S/2 and 90S/3 assemblies; check the identification plate on the coupling body or existing damper reference before ordering.
