Peterbilt 389 Glider Bug Shields

Frequently Asked Questions About Peterbilt 389 Glider Bug Shields

What is a bug shield and what does it do?

A bug shield, also called a hood shield or deflector, mounts to the front edge of the hood and helps redirect airflow up and over the windshield. This deflects bugs, road debris, and rain away from the glass, improving visibility and keeping the front of your truck cleaner during long hauls.

Will this bug shield fit my Peterbilt 389 Glider?

Bug shields in this category are designed specifically for the Peterbilt 389 Glider hood profile. Because hood styles and trim options can vary between production years and glider kit builders, we recommend confirming your hood style and checking the listed fitment notes on each product page before ordering to ensure a proper fit.

What materials are these bug shields made from, and what finish options are available?

Bug shields for the 389 Glider are typically offered in stainless steel or chrome-plated finishes. Stainless steel options provide a durable, low-maintenance surface, while chrome-plated shields offer a brighter, mirror-like shine that many owners prefer for a show-quality look. Some finishes may require occasional cleaning and polishing to maintain their appearance and resist water spotting.

How is a bug shield installed, and is drilling required?

Most bug shields attach using existing mounting points or included brackets and hardware, with adhesive-backed or clip-on options available for some models. Certain shields may require drilling small mounting holes into the hood, so it's important to review the installation instructions and included hardware for your specific shield before starting. If you're unsure about drilling into your hood, look for no-drill or bracket-mounted options.

Will a bug shield affect airflow, visibility, or cause wind noise?

A properly fitted bug shield is designed to work with your truck's airflow rather than against it, and most drivers report minimal to no noticeable wind noise once installed. Because the shield sits at the leading edge of the hood, it should not obstruct your view of the road. If you notice excessive noise or vibration after installation, double-check that all mounting hardware is properly tightened and the shield is seated correctly against the hood.
