Description
Overview:
The Knott-Avonride Bellows Kit in red is a protective cover for trailer coupling mechanisms, made from a durable, flexible elastomer to shield moving parts from dust, grit, and road spray. It helps keep lubricants where they are needed, reduces wear on linkages, and supports smooth, reliable operation of the coupling and overrun linkage. Designed for Knott Avonride systems, it is suitable for use on trailers fitted with the KRV13 or KRV20 couplings. The bright red finish aids quick identification during inspections. Supplied as a bellows kit under MPN 577003, it is intended for routine maintenance or replacement where the original gaiter has split, perished, or become loose, helping to maintain performance and extend component life.
Key Features:
- Designed for Knott Avonride KRV13 and KRV20 couplings
