Upgrade the exterior finish of your Peterbilt with stainless steel upper door under-window trim designed for 567 and 579 models with door-mounted mirrors. This aftermarket trim is built from stainless steel and is intended to enhance the area beneath the window and along the upper door for a clean, polished appearance. The trim is typically sold as a pair and uses a rivet-mount style installation for secure placement along the door. Its stainless steel construction helps maintain a consistent finish suited for demanding environments while complementing other exterior chrome and stainless accents. Made as a high-quality aftermarket replacement part and backed by a warranty against defects in workmanship and materials, this trim offers a practical way to refresh worn exterior details or complete a custom stainless steel styling theme.
