Peterbilt 389 Bug Shields

Frequently Asked Questions About Peterbilt 389 Bug Shields

What exactly is a bug shield and what does it do?

A bug shield, also called a hood shield or hood deflector, is a protective panel that mounts to the leading edge of the hood on your Peterbilt 389. It helps deflect bugs, road debris, gravel, and rain away from the windshield, reducing pitting on the glass and keeping your view clearer while driving.

Will a bug shield fit my Peterbilt 389 without modification?

Bug shields designed for the Peterbilt 389 are built to match the contour of that specific hood, so they should fit without cutting or reshaping. That said, hood styles and production years can vary slightly, so it is a good idea to confirm the shield is listed for the 389 specifically and check any fitment notes on the product page before ordering.

What materials are these bug shields made from, and how do they hold up?

Most bug shields for the 389 are made from stainless steel, chrome-plated stainless, or durable ABS plastic. Stainless and chrome versions tend to hold up well against road debris and are easy to keep polished, while plastic versions are lighter and often more budget friendly. The right choice usually comes down to whether you want a mirror-finish look or a lower-maintenance option.

How is a bug shield installed, and do I need any special tools?

Installation typically involves mounting brackets or clips that attach along the top edge of the hood, often using existing holes or simple adhesive/tape backing depending on the model. Most shields can be installed with basic hand tools in well under an hour, but we recommend reviewing the included instructions or product listing details before starting, since mounting hardware can vary between shield styles.

How do I clean and maintain a bug shield to keep it looking good?

For chrome or stainless shields, regular washing with mild soap and water followed by a chrome polish will help maintain the shine and prevent water spotting or road film buildup. Plastic shields generally just need a wipe down with soap and water. Avoid abrasive pads or harsh chemical cleaners on either type, since they can scratch the surface or dull the finish over time.
