A hydraulic actuator assembly is configured to receive a pressurized fluid from a pump. The hydraulic actuator assembly includes a housing and a piston arranged concentrically with respect to a longitudinal axis, wherein the housing is configured to receive a first portion of the pressurized fluid to displace the piston relative to the housing. The hydraulic actuator assembly also includes a sleeve arranged concentrically with respect to the housing and to the piston, and configured to restrain the piston relative to the housing and receive a second portion of the pressurized fluid from the pump to selectively release the piston. A vehicle including a suspension corner connecting the vehicle's road wheel to the vehicle's body, the fluid pump, and the subject hydraulic actuator assembly to change the vehicle's ride height at the suspension corner is also disclosed. The vehicle may also include a controller configured to control the actuator assembly.
