Rear Side Window Deflect ors

The WeatherTech Rear Side Window Deflectors (SKU WEA81930, MPN 81930) are precision-engineered acrylic window visors designed for GM fullsize crew cab trucks from 2019–2020. These snap-in deflectors mount directly to the rear side windows, allowing fresh air circulation while deflecting rain, wind, and road spray away from the vehicle's interior and cargo area. The 3mm thick dark smoke acrylic construction provides optimal clarity and UV protection without the aesthetic compromise of heavier tinting.

Measuring 47 inches in length with a 13-inch height and 2-inch depth, this pair fits the rear side windows of full-size GM trucks with factory precision. The snap-in mounting system requires no drilling, adhesives, or permanent modification—deflectors seat securely in the window channel and can be removed without leaving residue. The dark smoke tint reduces interior sun exposure and glare while maintaining driver visibility. Lightweight at just 2 pounds for the pair, the deflectors add negligible weight while improving cabin comfort during highway driving and towing operations.

These deflectors are ideal for owners of 2019–2020 GM fullsize crew cab trucks who spend significant time on highways, in dusty conditions, or during heavy rain. Off-road and ranch work benefits from reduced window buffeting and dust infiltration. Long-haul drivers appreciate the improved aerodynamics and reduced wind noise at highway speeds. Window deflectors also serve practical function during vehicle camping and off-road recovery operations, allowing camp-side ventilation without weather exposure. WeatherTech's snap-fit design ensures compatibility with crew cab door geometry while maintaining the factory fit and finish of modern trucks.
