Frequently Asked Questions About Peterbilt 389 Hoods & Related

Will a replacement hood fit my Peterbilt 389 exactly like the factory hood?

Aftermarket and OEM-style hoods for the Peterbilt 389 are built to match factory dimensions and mounting points, but fitment can vary slightly depending on the manufacturer and your truck's specific hood configuration and year. Before ordering, check the hood style, hinge type, and any pre-drilled openings for lights or air intakes to make sure it matches your current setup.

What material are these hoods made of, and how does that affect durability?

Peterbilt 389 hoods are typically molded from fiberglass, which offers a good balance of durability, repairability, and weight compared to steel. Fiberglass hoods can flex slightly on rough roads and are generally easier to patch if they sustain minor cracks or chips, though severe damage may require professional repair or replacement of the affected panel.

Do these hoods come primed and painted, or will I need to paint them myself?

Most replacement hoods are sold in gelcoat or primer finish and are not painted to match your truck at the factory. You should plan on having the hood painted by a professional after purchase, especially if color-matching to your existing paint is important. Some sellers may offer painted options, so check product listings carefully.

Can I install a new hood myself, or should I have a professional do it?

Hood installation involves aligning and securing the hood to the hinge and latch assemblies, connecting any wiring for lights that run through the hood, and making sure the hood opens and closes without rubbing on the fenders or cab. While experienced DIY mechanics can handle this job with the right tools and a helper, many owners choose a professional shop to ensure proper alignment and avoid stress cracks from an improper fit.

Are the mounting points and hardware included with the hood, or sold separately?

This varies by product and manufacturer. Some hoods include mounting hardware, hinges, or brackets, while others are sold as the hood shell only, requiring you to reuse your existing hardware or purchase it separately. Always review the product description or contact us before ordering to confirm exactly what is included.
