An extension screed is for a paving vehicle screed assembly that includes a main screed. The extension screed includes two base members movably connectable with the main screed and two vertical actuators each extending between the main screed and a separate base member. Each vertical actuator linearly displaces the connected base member with respect to the main screed in opposing vertical directions. A carriage preferably includes an inner frame movably connected with the base members and an outer frame slidably disposed about the inner frame and configured to support a screed plate. The vertical actuators vertically displace the carriage and alternatively pivot the carriage within a vertical plane. Further, a first horizontal actuator displaces the inner frame with respect to the two base members in opposing horizontal directions and a second horizontal actuator displaces the outer fame with respect to the inner frame in opposing horizontal directions.
