Offering a streamlined design with heavy-duty construction, the Herd Aero aluminum 4-post grille guard is built to provide reliable front-end protection for Mack Pinnacle CHN and CHU trucks. This grille guard features an 18-inch extruded aero-style aluminum bumper, four fully boxed-in uprights, and 3-inch horizontal tubes designed for structural durability. Standard features include side and center eyebolts, integrated light mounting tabs, and a Herd mirror-polished finish. Base configurations are typically offered without lower rake, slam latch, lift assist, or light cutouts. Sold individually as a high-quality aftermarket replacement part rather than an OEM component, this grille guard includes a manufacturer warranty covering defects in materials and workmanship from the date of purchase. This item ships directly from the manufacturer and may arrive separately from other items in the same order. As with most fit-specific heavy-duty truck accessories, verifying the mounting hole pattern and confirming compatibility before installation is recommended.
