Linear Vs. Digressive Pistons The linear piston creates a force curve that features an increase in force directly related to an increase in speed -- the quicker the shock moves, the stiffer it becomes. The digressive piston creates a force that does not increase proportionately to an increase in speed -- the force curve does not increase directly related to shock speed.
