A Brief History of Shock Absorbers

All shocks are designed as hydraulic devices to some degree; that is, Glass Shocks require the movement or motion of some form of liquid in order to operate.In fact, early units were pure hydraulic shocks, meaning that they contained only fluid. Unfortunately, these designs offered restricted performance, as the liquid inside shock absorbers tended to foam or form bubbles, thus reducing the effectiveness of the shock and accelerating wear.Now thanks to advancements in technology, shocks contain pressurized nitrogen gas in addition to hydraulic liquids. Not only does nitrogen gas offer significant improvements over pure hydraulic predecessors, but pallet systems  is inert and completely safe as well.
