GRILLS

Grills For Peterbilt Trucks

The grille is one of the most recognizable styling elements on a Peterbilt truck — the chrome bar grille on a classic 389 is as iconic as the model itself. Beyond aesthetics, the grille protects the radiator, charge air cooler, and condenser from road debris while directing airflow through the cooling system. We carry replacement grilles in OEM-style and custom chrome finishes for Peterbilt trucks including the 389, 379, 567, 579, and other popular models.

Frequently asked questions about grills

Will a damaged grille affect my Peterbilt's cooling performance?

A grille that's been pushed back into the radiator or condenser from a front-end impact can restrict airflow and physically damage the cooling cores. Even a grille that appears cosmetically damaged but is still properly positioned should be checked to ensure it's not touching or compressing the radiator fins. Bent grille bars that deflect airflow away from the cooling stack can contribute to marginal overheating in hot weather or at low road speeds.

Are aftermarket chrome grilles as durable as OEM Peterbilt grilles?

Quality varies significantly among aftermarket grille manufacturers. The best aftermarket units use ABS plastic substrates with triple-chrome plating that holds up well to road vibration and temperature cycling. Cheaper chrome grilles use thinner plating that can peel or bubble within a season or two of use. For owner-operators who keep their trucks long-term, investing in a quality grille from a reputable manufacturer pays off in longevity and retained appearance.

Can I replace just a broken grille bar, or do I need the entire grille assembly?

This depends on the grille design. Some Peterbilt grille styles use individual bar inserts that can be replaced separately, which is a cost-effective option for isolated damage. Other designs are a single molded assembly where the bars aren't individually serviceable. Check whether your specific model's grille has replaceable bar inserts before assuming a full assembly replacement is necessary.
