Built to balance durability with a streamlined appearance, the Herd Aero 4 Post Grille Guard is designed for 2001-2014 Western Star 4900FA SFA trucks with straight-through frames. This heavy-duty aluminum grille guard features four fully boxed uprights, 3-inch horizontal tubes, and an 18-inch aero-style extruded aluminum bumper to help protect the front end. Standard design elements include light mounting tabs, side and center eyebolts (on select configurations), and Herd's signature mirror-polished finish. Buyers can choose between a standard version or an option equipped with Slam Latch and Lift Assist features. This grille guard is sold individually as a high-quality aftermarket replacement part and includes a manufacturer warranty covering defects in materials and workmanship. It ships directly from the manufacturer and may arrive separately from other items in the same order. As with most fitment-specific truck accessories, verifying vehicle compatibility and mounting details before ordering is recommended to ensure proper installation.
