A stroke dependent damper assembly includes: a damper housing, an end cap, a floating piston slidably received in an interior cavity for movement along a longitudinal axis between a retracted position, an intermediate position, and an extended position, the floating piston being unbiased and free floating in the interior cavity; a metering pin extends longitudinally from the floating piston along a longitudinal axis to a metering pin end, the metering pin being received in the through bore to define an aperture between an inner surface of the through bore and an outer surface of the metering pin that varies in size as the floating piston moves between the retracted position, the intermediate position, and the extended position, the orifice has a first dimension when the metering pin is in the intermediate position, the orifice has a dimension smaller than the first dimension when the floating piston is moved away from the intermediate position, and the metering pin end protrudes longitudinally outward from th
