Frequently Asked Questions About Peterbilt 379 Grilles

What years and models are compatible with these Peterbilt 379 grilles?

Our Peterbilt 379 grilles are designed to fit all 379 models manufactured from 1987 to 2007. This includes both short hood and long hood variants. The mounting points remained consistent throughout these production years, so any grille marked for the 379 will bolt directly to your truck. However, if you have an extended hood 379, double-check the measurements as some aftermarket grilles may require minor adjustments to the mounting brackets.

Are these grilles made from stainless steel or aluminum, and which is better for my truck?

We carry both stainless steel and aluminum grilles. Stainless steel grilles (typically 304-grade) offer superior corrosion resistance and maintain their shine with minimal maintenance, making them ideal for trucks exposed to road salt or coastal environments. Aluminum grilles are significantly lighter (about 40% less weight) and more budget-friendly, but require more frequent polishing to maintain their appearance. For daily drivers and work trucks, stainless steel provides the best long-term value despite the higher initial cost.

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

Installation typically takes 2-3 hours and requires basic hand tools: socket set (typically 13mm and 15mm), Phillips and flathead screwdrivers, and possibly a drill if you're installing accessories. Most grilles use the factory mounting points and come with necessary hardware. The main challenges involve carefully removing the old grille without damaging the hood or fenders, and ensuring proper alignment before fully tightening all bolts. Many customers successfully complete this as a weekend project, though professional installation runs about $150-300 if preferred.

What's the difference between louvered, vertical bar, and punch hole style grilles?

Louvered grilles feature horizontal slats that provide maximum airflow while offering a classic, aggressive look. Vertical bar grilles (with 13-16 bars typically) deliver a traditional appearance and moderate airflow, making them popular for show trucks. Punch hole grilles offer a unique custom appearance with various hole patterns (round, oval, or rectangular) and provide good airflow while preventing larger debris from entering. Your choice should balance aesthetics with your cooling needs - working trucks often benefit from louvered designs, while show trucks can prioritize appearance with vertical bars.

Will aftermarket grilles affect my engine cooling, and do they come with bug screens?

Quality aftermarket grilles are designed to match or exceed OEM airflow specifications. However, grilles with tighter patterns or additional decorative elements may reduce airflow by 10-15%. If you frequently haul heavy loads or operate in hot climates, choose grilles with larger openings or louvers. Most grilles do not include bug screens, but we offer compatible screens separately for about $50-100. These screens are essential for protecting your radiator and are designed to snap in behind the grille without requiring modifications.
