The integral cab side extender or fairing for a tractor-trailer provides reduction of aerodynamic drag. The cab extender is a unitary structure including a rear-quarter-panel-forming portion having a rear wall, a side wall and a front wall. The side wall and rear wall of the rear-quarter-panel-forming portion form an integral fairing. The side wall has a sinuous, progressively rearwardly and laterally outwardly flared sidewall-forming surface and the rear wall has a rearwardly laterally outwardly flared rear wall-forming surface which converges with the flared sidewall-forming surface to form the fairing. The method for mounting the rear-quarter-panel-forming cab extender to a cab of a tractor includes the steps of: sliding the rear-quarter-panel-forming cab extender over exposed frame members of the cab; positioning a cutout provided in the front wall of the cab extender over a striker of a door latch; aligning a flange of the rear wall of the cab extender against a rear end edge portion of a rear outer panel of the cab; and fixing the cab extender to the exposed frame members and to the rear outer panel of the cab.
