Add serious front-end protection with the Herd Aero aluminum 4-post grille guard, engineered for Peterbilt 387 models from 1999 through 2011. This high-quality aftermarket grille guard features an 18-inch extruded aero-style aluminum bumper, four fully boxed-in uprights, and 3-inch horizontal tubes designed to provide structural strength while maintaining a streamlined look. Additional standard features include side and center eyebolts, light mounting tabs, and a mirror-polished Herd finish. Depending on the configuration, options such as a slam latch or lift assist may be available. Each grille guard is sold individually, ships directly from the manufacturer, and includes warranty coverage against defects in materials and workmanship. Classified as a heavy-duty bumper and grille guard rather than an OEM component, it is important to confirm mounting patterns and fitment details before installation to ensure proper compatibility.
