TOP-MAX Heated Upper Side Mirror Glass for Freightliner Cascadia 2008–2017 — Black ABS Plate, Flat Direct-Fit (Driver/Passenger)

TOP-MAX heated upper side mirror glass for Freightliner Cascadia (2008–2017) is a direct-fit, flat replacement mirror with a durable black ABS plate and integrated heating to clear frost and condensation quickly.

When a cracked or fogged side mirror compromises visibility, this TOP-MAX replacement is engineered to restore a clear rearward view without modifying your truck. It is made to match the OE TL-28716A footprint for both driver and passenger sides on Freightliner Cascadia models from roughly 2007 through 2018. The unit provides flat, distortion-free glass, a built-in heater for de-icing, and a rugged plastic backing that secures to the original mirror housing.

How will this mirror improve visibility in cold or wet weather?

The integrated heating element warms the glass surface to prevent frost, ice, and heavy condensation from obscuring your view. It reduces the time you spend manually scraping or waiting for defrost cycles and helps maintain a clearer sightline during wet or cold conditions.

• Built-in electric heater removes fog and ice faster than passive glass.
• Flat mirror surface reduces visual distortion for accurate distance perception.
• Improves safety during rain, snow, and temperature swings.

Is installation difficult — will it fit my Freightliner Cascadia?

This TOP-MAX replacement is designed to match the original OE TL-28716A shape and mounting points for an easy swap. No custom trimming or adapters are required for compatible Cascadia model years; simply detach the old glass, connect the heater wiring, and press the new unit into place.

• Direct-fit for Freightliner Cascadia 2007–2018 driver and passenger sides.
• Uses original mounting locations and electrical connector for the heater.
• Remove the protective film from the glass before use to avoid haze.

What features and build quality can I expect from this replacement?

The mirror pairs flat optical glass with a tough ABS backing plate for reliable performance under heavy daily use. The design purposefully excludes auto-dimming and blind-spot sensors, focusing instead on durable construction and dependable heating for core visibility needs.

• Flat glass for improved clarity and minimized distortion.
• ABS back plate for impact resistance and long-term stability.
• Heated element integrated into the glass assembly for fast de-icing.

Will this replacement work with my truck’s electrical system?

The heating element is intended to connect to the vehicle’s mirror heater circuit and operates with the stock wiring used on compatible Cascadia models. If your truck originally had heated mirror glass, this unit will plug into the same connector and draw power in the same way.

• Designed for use with existing heated mirror wiring on Freightliner Cascadia.
• Matches OE TL-28716A electrical connection style for easy hookup.
• No additional relays or controllers are typically required.

This TOP-MAX heated upper side mirror glass is intended for Freightliner Cascadia owners or fleet technicians who need a reliable, OE-style replacement for worn, broken, or fogging upper side mirrors. It’s ideal for drivers who prioritize clear rear visibility in cold and wet climates and for service shops that want a durable, direct-fit part without extra sensor features. Note that this product replaces flat heated glass only and does not include auto-dimming or blind-spot sensor capabilities.
