Overrun Dampers
(Products quantity: 33)An overrun damper controls the movement of the coupling head and helps the brake system work smoothly. When choosing a replacement, match the mounting type, working length and load rating, because HAHN, GRAU, PEITZ/BPW and AL-KO versions differ in travel range and fit. This is usually the part replaced during coupling service or after noticeable wear in the overrun unit.
This category covers parts used to repair and adjust the overrun system on caravans and trailers. Selection should be based on working length, load capacity and compatibility with the exact setup, including AL-KO, Knott, PEITZ/BPW, HAHN or GRAU. If you are servicing the whole assembly, check also tow ball couplings, brake cables and stabiliser couplings. For maintenance work, jockey wheels and other trailer accessories are often useful. We also offer products from Knott.
