Peterbilt 389 Roof Trim

Frequently Asked Questions About Peterbilt 389 Roof Trim

What is roof trim and what does it do on my Peterbilt 389?

Roof trim is the decorative and protective molding that covers the seams and edges along the cab roof, including the areas around the visor and roof cap. It gives the cab a finished, streamlined look while helping to cover fasteners, seams, and edges that would otherwise be exposed to the elements.

Will this roof trim fit my specific Peterbilt 389 cab configuration?

Roof trim is typically designed to match the factory contours of the Peterbilt 389, but fit can vary depending on cab style, roof height, and whether you have a factory visor or aftermarket roof accessories installed. Always check the listed specifications and compare them to your truck's configuration before ordering, and reach out to our team if you're unsure about compatibility.

What materials and finishes are available for roof trim?

Roof trim is commonly offered in stainless steel or chrome-plated finishes for durability and a polished appearance. Stainless steel tends to hold up well against corrosion and is easier to maintain over the long haul, while chrome offers a brighter, mirror-like shine. Choosing between the two often comes down to personal preference and how much upkeep you're willing to do.

How do I install roof trim, and can I do it myself?

Most roof trim pieces are designed to attach using adhesive, clips, or existing mounting points along the roof line, depending on the specific product. Many customers install these panels themselves with basic tools, but because the work is done at height and involves careful alignment, some drivers prefer having a shop handle the installation to ensure a clean, secure fit.

How do I keep roof trim looking good and prevent corrosion or damage?

Regular washing with a mild soap and water solution helps prevent road grime and salt buildup from causing pitting or corrosion, especially on chrome finishes. Avoid abrasive pads or harsh chemical cleaners, and consider applying a metal polish or protectant periodically to maintain shine and extend the life of the trim.
