Adjustable cab extender

摘要

A cab extender assembly for selectively changing the aerodynamic drag on a vehicle having a longitudinal axis includes a fixed cab extender (12) and at least one track (28) extending generally parallel to the longitudinal axis of the vehicle. An adjustable cab extender (10) has at least one moveable member that is engaged in the track (28). An actuator assembly (56) is configured for selectively reciprocating the adjustable cab extender (10) along the track and with respect to the fixed cab extender.
