Peterbilt 389 Glider Roof Trim

Frequently Asked Questions About Peterbilt 389 Glider Roof Trim

What exactly is roof trim, and what does it cover on my Peterbilt 389 Glider?

Roof trim refers to the decorative and protective molding or panel covers that fit along the edges and seams of the cab roof, including areas around the roof cap, marker light bar, and side edges where the roof meets the cab structure. It is designed to give the cab a finished, factory-style appearance while covering seams, bolts, or transition points on the roofline.

Will this roof trim fit my specific Peterbilt 389 Glider cab, since gliders can have different roof configurations?

Glider kits can vary depending on the builder and the roof style installed, such as flat top, high rise, or aero configurations, so fitment is not always universal. Before ordering, check the listed roof style and cab dimensions on the product page against your truck, and if you are unsure, reach out to our team with your cab details so we can confirm the correct trim piece for your setup.

What materials and finish options are available for this roof trim?

Roof trim for the 389 is typically offered in stainless steel or chrome-plated finishes, giving you a durable, corrosion-resistant piece that matches other polished trim on the truck. Stainless steel options tend to hold up well against road grime and weather, while chrome pieces offer a brighter, mirror-like shine. Check each listing for the specific finish and gauge of material used.

How is the roof trim installed, and do I need any special tools?

Most roof trim pieces are installed using existing mounting points, adhesive backing, or included clips and fasteners, depending on the specific product. Basic hand tools are usually sufficient, but some pieces may require drilling or precise alignment to sit flush against the roof panel. We recommend reviewing the installation instructions included with your specific trim piece or consulting with a professional installer if you are not comfortable with the process.

How do I keep the trim looking good and prevent rust or corrosion over time?

Regular washing with a mild soap and water solution helps remove road salt, dirt, and grime that can dull the finish or contribute to corrosion, especially around edges and fastener points. For chrome or stainless trim, using a dedicated metal polish periodically will help maintain shine and protect against pitting. Avoid harsh abrasive cleaners, and inspect mounting points occasionally to ensure the trim remains securely attached.
