The KNOTT 576002 Coupling Head Damper (12mm hole) is a genuine Knott-Avonride replacement unit suitable for trailers rated between 1400kg and 2700kg. Designed to restore smooth towing performance, this damper helps eliminate banging or jolting between trailer and vehicle during braking or acceleration — a common sign of damper failure.
Compatible with Knott KF, KFG and KR coupling models (weight ratings 20 – 2000kg to 27 – 2750kg), this high-quality replacement is commonly fitted to newer Ifor Williams trailers and many other makes. Built for durability and reliable braking performance, it ensures safer, smoother towing and long service life.
