A position-relative damper assist system for use with a vehicle, the position-relative damper assist system comprising: top and bottom mounting components cooperating with one another to define a corresponding stroke distance between them, and being operable with respect to one another between compression and extension modes along said stroke distance, the top mounting component being operatively connectable to a frame of the vehicle, and the bottom mounting component being operatively connectable to a supporting component of the vehicle; a piston assembly being operatively disposed between the top and bottom mounting components , the piston assembly having a piston head being displaceable within a chamber defined about a portion of one of the top and bottom mounting components , the piston head being provided with at least one fluid passage for allowing fluid of the chamber to travel from one side of the chamber to another side of the chamber via the piston head of the piston assembly , in order to provide a corresponding damping effect; an adjustment assembly cooperating with the piston head of the piston assembly for adjustably varying an effective cross-sectional profile of the at least one fluid passage in order to in turn vary a corresponding flow rate of fluid passing through said at least one fluid passage , and in turn vary the resulting damping effect; and a biasing assembly cooperating with the adjustment assembly for selectively varying a configuration of the adjustment assembly in response to a given input indicative of the positioning of the piston assembly within the stroke distance , in order in vary the resulting damping effect in response to a corresponding displacement-profile provided by the biasing assembly , characterized in that the adjustment assembly is contained inside the piston head , and configured to adjustably vary the effective cross-sectional profile of the at least one fluid passage inside said piston head . top and bottom mounting components cooperating with one another to define a corresponding stroke distance between them, and being operable with respect to one another between compression and extension modes along said stroke distance, the top mounting component being operatively connectable to a frame of the vehicle, and the bottom mounting component being operatively connectable to a supporting component of the vehicle; a piston assembly being operatively disposed between the top and bottom mounting components , the piston assembly having a piston head being displaceable within a chamber defined about a portion of one of the top and bottom mounting components , the piston head being provided with at least one fluid passage for allowing fluid of the chamber to travel from one side of the chamber to another side of the chamber via the piston head of the piston assembly , in order to provide a corresponding damping effect; an adjustment assembly cooperating with the piston head of the piston assembly for adjustably varying an effective cross-sectional profile of the at least one fluid passage in order to in turn vary a corresponding flow rate of fluid passing through said at least one fluid passage , and in turn vary the resulting damping effect; and a biasing assembly cooperating with the adjustment assembly for selectively varying a configuration of the adjustment assembly in response to a given input indicative of the positioning of the piston assembly within the stroke distance , in order in vary the resulting damping effect in response to a corresponding displacement-profile provided by the biasing assembly , <EOS>
