Frequently Asked Questions About Peterbilt 357/378 Roof Trim

What exactly is roof trim on a Peterbilt 357/378?

Roof trim refers to the exterior molding and cab panels that cover the roofline of the truck, including cab corner caps, roof edge molding, and center roof trim pieces. These parts cover seams and mounting points at the top of the cab, giving the truck a finished look while also helping protect the roof edges from weather exposure.

Will this roof trim fit my truck if I have a sleeper cab or a day cab?

Roof trim fit can vary between day cab and sleeper cab configurations, as well as between different cab roof heights and model years within the 357/378 lineup. Always check the product listing for specific cab type and year compatibility before ordering, and compare it against your VIN or existing trim dimensions if you are unsure.

What material is this roof trim made from, and how does it hold up?

Most roof trim pieces for these models are made from stainless steel or durable ABS plastic, depending on the specific part. Stainless steel trim tends to hold up well against corrosion and road debris over time, while plastic trim is generally lighter and more affordable but may be more prone to fading or cracking with prolonged sun exposure.

Does this roof trim come pre-drilled, and will I need to modify my cab to install it?

Many roof trim pieces are designed to bolt on using existing factory mounting holes, so no drilling should be required in most cases. However, some replacement or aftermarket pieces may need slight adjustments or trimming to align properly, so it is a good idea to review the installation notes on each listing or reach out to us if you have questions before you install.

Can I install roof trim myself, or should I have a shop do it?

Most roof trim pieces are straightforward to install with basic hand tools and can typically be done by an experienced DIYer in a driveway or shop setting. That said, if the trim involves working near roof-mounted lights, antennas, or sealant work to prevent leaks, some owners prefer to have a professional handle the installation to ensure a clean, weather-tight fit.
