Genuine Knott-Avonride Coupling Damper for Knott-Avonride couplings AV30, KFG30 & KRV30

Trailer coupling dampers are sometimes referred to shock absorbers this is because the damper produces a cushioning effect to prevent the trailer from slamming when braking. When you apply the brakes your trailer will try to slam into the car this is prevented by the damper compressing inside the coupling and applies the brakes as and when it is needed giving you control of your trailer when towing.

How to know if your coupling damper needs changing?

The caravan or trailers coupling dampers job is to give smooth and controlled braking. When the damper has failed it is very noticeable, you will notice a slamming or snatching effect when braking. It is always worth checking the brake adjustment as this can give the same effect as a failed damper. Coupling dampers for overrun braking systems are pressurised when assembled, meaning it should take a considerable amount of pressure to push the coupling head back by hand. If you can push the coupling head back easily or it feels springy then this generally would mean the damper needs changings as it has failed.
