A damper having a hydraulically-adjustable preload. The damper includes a main damper cylinder, a damping piston and a damping rod movable within the main damper cylinder. A surface feature and a sleeve with a preload flange are coupled to a portion of an exterior surface of the main damper cylinder. The sleeve is movable with respect to the surface feature in a direction along the axis of the main damper cylinder. A spring is located surrounding a portion of the external surface of the main damper cylinder, and has one end abutting the preload flange and another end coupled to the damper. The sleeve and the surface feature are disposed such that a change in an amount of hydraulic fluid between the sleeve and the surface feature causes the preload flange to change a preload on the spring.
