For every vehicle class and purpose, KW has an optimally-adjusted coilover suspension – be it comfortable, sporty, or performance-oriented. This challenging goal is achieved with innovation, patented KW technology, and an independently adjustable rebound and compression stage damping. Here, we are not explicitly tied down to mono-tube or twin-tube technology, rather we draw on all technologies and take advantage of their respective benefits. Where hydraulic design is concerned, we decide whether to employ mono, twin or triple-tube dampers with low pressure gas filling, or whether to use a separate 2 reservoir. In terms of tuning we consciously try to control the body acceleration 1 from the very beginning via low-speed damping and we place great emphasis on the fine tuning of the high-speed damping through elaborate two-step twin valve technology in the compression and rebound stage. This, for example, allows our customers to finely tune the all-important low-speed compression damping on the patented TVC-A dump valve over a wide and extremely efficient range without negatively influencing the high-speed compression damping KW MONO-TUBE DAMPER KW TWIN-TUBE DAMPER KW TRIPLE-TUBE DAMPER values which are decisive in terms of comfort. This two-step pressure valve The KW mono-tube damper always comprises two valves: the working piston with twin-valve rebound valve The KW twin-tube damper consists of a damper housing, cylinder tube, guiding and sealing package, piston As the name suggests, the KW triple-tube damper consists of three aligned housings: the damper housing, technology allows two incompatible characteristics – sportiness and ride (two-step rebound stage valve) and twin-valve compression valve (two-step compression stage valve).
