Peterbilt 375/377 Roof Trim

Frequently Asked Questions About Peterbilt 375/377 Roof Trim

What exactly is roof trim, and what does it do?

Roof trim refers to the exterior molding and panels that cover the roofline of the cab, typically running along the top edge and corners where the roof meets the cab sides. It covers seams, protects against water intrusion, and gives the cab a finished, factory-style appearance. On Peterbilt 375/377 models, this trim is often stainless steel or chrome-plated to match the rest of the truck's exterior brightwork.

Will this roof trim fit my specific Peterbilt 375 or 377 model year?

Cab designs can vary slightly across production years, so it's important to check the fitment notes on each product listing before ordering. If you're unsure whether a piece matches your cab configuration, measure your existing trim or reach out to our customer service team with your truck's year and cab style so we can confirm compatibility before you buy.

What material and finish options are available?

Most roof trim for these models is made from stainless steel, chosen for its durability and resistance to rust and road grime. Finish options typically include polished or brushed stainless, so you can match the look to the rest of your truck's existing trim and accessories.

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

Installation methods vary by product, some pieces are held in place with adhesive-backed tape, while others use clips, screws, or a combination of fasteners that follow the factory mounting points. Basic hand tools are usually sufficient, but we recommend cleaning the mounting surface thoroughly before installation to ensure proper adhesion and a secure, long-lasting fit. Always follow the specific instructions included with your part.

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

Regular washing with a mild soap and water solution helps remove road salt, dirt, and grime that can lead to corrosion over time. For stainless trim, a dedicated metal polish applied periodically will help maintain shine and protect the surface. Avoid harsh abrasive cleaners or pads, as these can scratch the finish and make the trim more susceptible to buildup and staining.
