I have some general KW damper questions. I would like to know something about the workings of the dampers. Are they mono-tube or twine tube? If they are mono-tube are they piston separated or just high pressure gas? If they are twine tube do they use bags to prevent foaming? What type of valves do they use? Do the rebound adjustable dampers use a check valve in the bypass? Do the double adjustable use two bypasses or compression on the valve stack? I have not seen any technical data on their dampers.
Have you checked out KW's site? They've got a wealth of information on their various struts with some great cutaways for the damper setups and a breakdown on the valve construction they use.
