Peterbilt Grilles

Frequently Asked Questions About Peterbilt Grilles

Will these grilles fit my specific Peterbilt model and year?

Our Peterbilt grilles are designed for specific model years and configurations. Most aftermarket grilles fit Peterbilt models 379, 389, 567, and 579 from various year ranges. Always check the product description for exact fitment details, including whether your truck has a short hood, long hood, or extended hood configuration. If you're unsure, contact us with your OEM number and we'll verify compatibility before you order.

What's the difference between stainless steel and chrome-plated grilles?

Stainless steel grilles are made from solid stainless material throughout, offering superior corrosion resistance and durability - they won't chip or peel like chrome can. Chrome-plated grilles have a mirror-like finish over a base metal and cost less upfront, but may require more maintenance and eventual re-chroming. For trucks in harsh weather conditions or heavy salt exposure, stainless steel is the better long-term investment.

How difficult is the installation process, and what tools do I need?

Most Peterbilt grille replacements take 2-4 hours and require basic hand tools including socket sets, screwdrivers, and trim removal tools. You'll need to remove the hood, disconnect any bug screens or winter fronts, and carefully unbolt the existing grille. Some models require removing the headlights for access. While many drivers complete this as a DIY project, proper alignment during reinstallation is critical to prevent hood interference or gaps.

Do aftermarket grilles affect engine cooling or airflow?

Quality aftermarket grilles are engineered to maintain or improve upon OEM airflow specifications. Look for grilles with properly spaced bars or mesh patterns that don't restrict air intake. Avoid grilles with excessive chrome trim or decorative elements that block significant portions of the opening. If you're running heavy loads or in extreme temperatures, consider grilles specifically designed with maximum airflow in mind.

What grille styles and finishes are available for Peterbilt trucks?

Popular options include horizontal bar grilles, vertical bar designs, punch hole patterns, and custom billet styles. Finishes range from polished stainless steel and chrome to powder-coated black and custom colors. Many grilles also accommodate aftermarket emblems, LED accent lighting, or winter front attachments. Consider your truck's use - show trucks often feature ornate designs while working trucks benefit from simpler, more durable styles.
