Description
Overview:
The Coupling Damper for Knott KF/KR13 C/D (MPN 763 864) is a replacement overrun damper designed to control drawbar movement and braking response on selected Knott KF/KR13 C/D coupling heads. It is manufactured for trailer and towing applications where a consistent damping force is required to reduce snatch and oscillation under braking. Built to the specification used by Stabilus, the German damping specialist, this unit matches the original fit on compatible Knott couplings and is intended for straightforward like-for-like replacement. Key dimensions are taken from the standard drawing to help confirm fitment, including an M10 threaded end, closed length of 320 mm and extended length of 530 mm. Suitable for use on plant trailers, general-duty trailers and other towed equipment fitted with the relevant Knott overrun coupling assemblies.

Typical Applications:
Used within the drawbar housing of Knott KF/KR13 C/D overrun couplings on trailers and plant transporters to moderate the telescopic movement during braking. Typical installations include light plant trailers, builders' trailers, general-purpose trailers and similar towed equipment that use the specified Knott coupling head. The dimensional data provided allows verification against the installed unit before replacement.
