Peterbilt 357/378 Bug Shields

Frequently Asked Questions About Peterbilt 357/378 Bug Shields

What is a bug shield and what does it do?

A bug shield, also called a hood shield or bug deflector, is a hood-mounted accessory that helps redirect airflow up and over the windshield. This helps deflect insects, road debris, and rain away from the glass, improving visibility and keeping the front of the hood cleaner during long hauls.

Will this bug shield fit my Peterbilt 357 or 378 without modification?

Bug shields in this category are designed to fit the specific hood contours of the Peterbilt 357 and 378 models. That said, hood styles can vary slightly by production year and configuration, so it's important to confirm your truck's exact model and year against the product listing before ordering. If you're unsure, our customer service team can help verify fitment.

What materials and finishes are available?

Bug shields are typically available in stainless steel, chrome-plated, or durable ABS/plastic construction. Stainless and chrome options offer a polished, reflective look and added durability against corrosion, while plastic or composite shields are lighter weight and often more budget-friendly. Finish options may include polished chrome, brushed stainless, or painted-to-match styles depending on the specific product.

How is a bug shield installed, and can I do it myself?

Most bug shields mount to the top edge of the hood using adhesive tape, brackets, or a combination of both, depending on the specific product design. Many are designed for straightforward bolt-on or adhesive installation that can be completed with basic hand tools in a home garage or shop setting. Always follow the manufacturer's included instructions for proper placement and mounting to ensure a secure fit.

Will a bug shield affect my visibility or airflow while driving?

When properly installed, a bug shield is designed to improve your driving experience by reducing debris buildup on the windshield rather than obstructing your view. However, improper installation or an incorrect fit can create wind noise or minor visibility issues, which is why selecting the correct shield for your specific hood style and following installation guidelines closely matters.
