Freightliner SD 108-122 Roof Trim

Frequently Asked Questions About Freightliner SD 108-122 Roof Trim

What is roof trim and what does it do for my Freightliner SD 108/122?

Roof trim is the exterior panel or molding that covers the top edge of the cab, typically running along the roofline where it meets the upper body or fairing. It gives the cab a finished, factory-style appearance while also helping to cover seams, wiring, or mounting points along the roof edge. On the SD 108/122 models, it is designed to follow the specific contour of that cab style.

Will this roof trim fit both the 108 and 122 inch cab configurations?

Products listed in this category are designed to fit the Freightliner SD 108 and 122 cab styles as noted in the title and description. Because these two configurations share the same cab structure but differ in length, always check the specific part listing for confirmation of fitment before ordering, and compare against your truck's VIN or existing trim dimensions if you are unsure.

What materials and finishes are available for this roof trim?

Roof trim in this category is commonly available in stainless steel or painted/coated aluminum options. Stainless steel offers strong corrosion resistance and a bright finish that holds up well to weather and road exposure, while painted or coated options are typically chosen to match cab color. Check each listing for the specific material and finish called out by the manufacturer.

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

Most roof trim pieces are installed using existing mounting holes, clips, or adhesive backing depending on the specific part. Basic hand tools are generally sufficient for installation, though some pieces may require removal of existing trim, cab lights, or fairings first. If you are replacing a damaged piece, it helps to have the old trim on hand as a reference for alignment and hardware placement.

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

Regular washing helps remove road salt, dirt, and grime that can lead to pitting or discoloration over time, especially on stainless trim. For painted or coated trim, avoid abrasive cleaners or pads that can scratch the finish. Applying a metal polish on stainless pieces periodically can help maintain shine and slow down the effects of oxidation from sun and weather exposure.
