Keep your Peterbilt 579 looking sharp and aerodynamically efficient with these Cabin Sleeper Fairing Extenders designed specifically for 2022 and newer models. This driver side set includes both the upper plastic fairing extender and the lower aluminum fairing extender, giving you a complete solution for the left side of your cab sleeper. Whether you're replacing damaged fairings after a road incident or refreshing the look of an aging truck, this set delivers the OEM-style fit and finish your rig deserves.

The upper extender is constructed from durable, high-quality plastic that resists cracking and warping through changing temperatures and road conditions. The lower extender features sturdy aluminum construction, offering superior resistance to impacts, corrosion, and the everyday wear that comes with life on the highway. Together, these two materials are precision-matched to work seamlessly on the 2022+ Peterbilt 579, ensuring a flush, factory-style appearance that maintains the aerodynamic profile of your sleeper cab and helps protect fuel efficiency over long hauls.

Installation is straightforward for experienced truck technicians and body shop professionals. These fairing extenders are engineered to align with existing mounting points on the 2022+ Peterbilt 579, reducing fitment headaches and minimizing downtime for your truck or fleet.
