Restore clear visibility and upgrade safety with the High Soar Heated Lower Mirror Glass, designed for 2018–2024 Freightliner Cascadia trucks. This wide-angle lower mirror glass is engineered as a direct replacement for the factory lower section of the door mirror, helping you see more of the blind spot area beside your cab.
Precisely matched for the 2018, 2019, 2020, 2021, 2022, 2023, and 2024 Freightliner Cascadia model years, this lower mirror glass cross-references OE part numbers 28657, TL28657, 22-76858-507, 22-78606-507. Always verify your truck’s model year and OEM number before ordering to ensure correct fitment.
The integrated heating element is designed to help reduce frost, fog, and condensation buildup on the mirror surface in cold or wet weather. When properly connected, the heated lower mirror glass improves visibility in rain, snow, and icy conditions, supporting safer lane changes and maneuvering.
This lower mirror uses chrome plated glass with R320 curvature in a wide-angle convex design. The optical configuration is intended to provide an expanded field of view while maintaining reflection clarity, allowing you to better monitor the side of your trailer, adjacent lanes, and close-range blind spots near the truck.
For durability, the mirror glass is mounted on an ABS backing plate that offers stable support and secure mounting to the existing door mirror assembly. The combination of ABS backing and chrome plated glass is designed for long-term performance on highway and regional applications.
Manufactured to meet DOT and SAE standards, this heated lower mirror glass is built as a direct OEM-style replacement for the lower section of the Freightliner Cascadia door mirror. It is intended to install onto the original door-mount mirror frame with minimal or no modifications, making it suitable for both fleet maintenance and DIY repairs.
If you have any questions about compatibility, installation, or performance, the High Soar support team is ready to assist with timely and effective help so you can keep your Freightliner Cascadia safely on the road.
