A collaboration between KYB and Citroën has introduced a new suspension concept based on passive shock absorbers, but is said tocbe capable of approaching the high performance of the semi-active shock absorbers.
Until now, this technology has only been fitted to brand new manufactured vehicles, however, in 2022 it will be available as aftermarket parts from KYB Europe – part numbers 3348095 & 3448033. With this technology, the total stroke of the shock absorbers can be divided into three differentiated parts for which the shock absorber will provide different characteristics. The first part corresponds to the position around the centre of the stroke.
The second and third parts correspond to the positions close to the end of the rebound and the compression strokes, with the hydraulic compression and rebound stops responsible for providing additional energy absorption. This split is said to allow the shock absorbers main valves to focus on comfort and the two hydraulic stops take responsibility when more demanding situations are encountered, thus increasing both comfort and handling performance.
