Greetings, in my total distraction of designing the ultimate Off-road/Overland vehicle, I've been thinking about the following matter: Is it possible that a vehicle can be raised/lowered by pumping/removing extra oil into the shock absorber? And if so, would it affect the ride? Could it be done automated by a pump? Should I have already patented this idea ? This is really stuck in my mind and sadly I don't have the resources or expertise to fabricate something like this!
