Peterbilt 359 Bug Shields

Frequently Asked Questions About Peterbilt 359 Bug Shields

Will these bug shields fit my specific year Peterbilt 359?

Our bug shields are designed to fit Peterbilt 359 models from 1967 through 1987. However, there are slight variations between early models (1967-1979) and later models (1980-1987) due to grille and hood changes. When ordering, please verify your truck's year and whether it has the standard or extended hood configuration. If you have aftermarket modifications to your grille or hood, contact our support team with photos to ensure proper fitment.

What's the difference between aluminum and stainless steel bug shields?

Aluminum bug shields are lighter weight (typically 8-12 pounds) and more affordable, making them easier to install and adjust. They require regular polishing to maintain their shine. Stainless steel shields are heavier (15-20 pounds), more durable, and maintain their finish longer with less maintenance. Both materials provide excellent protection, but stainless steel offers superior resistance to road salt and harsh weather conditions. Consider your climate and maintenance preferences when choosing.

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

Installation typically takes 45-90 minutes and requires basic hand tools: a drill with metal bits, socket wrench set, measuring tape, and center punch. Most bug shields mount using existing hood hinge bolts plus 2-4 additional drilled holes. The most challenging part is achieving proper alignment with your hood line. We recommend having a helper to hold the shield in position while marking drill points.

Do bug shields actually protect against rock chips and bugs?

Yes, bug shields provide significant protection for your hood and windshield. They deflect airflow upward, carrying bugs and small debris over your cab. For rock chip protection, shields are most effective against small stones kicked up at highway speeds. However, they won't stop direct impacts from larger debris. Most customers report 70-80% reduction in bug splatter on their windshield and noticeable decrease in minor hood chips.

Which style looks best - straight, curved, or louvered?

Style preference varies by truck setup and personal taste. Straight shields offer a classic, clean look that complements stock 359s. Curved shields provide a more aggressive appearance and slightly better aerodynamics. Louvered shields add vintage appeal while allowing some airflow to the radiator, which can help in hot climates. Consider your truck's overall appearance - straight shields work well with original restorations, while curved or louvered options complement custom builds.
