WeatherTech 81942IMB Rear Side Window Deflectors Matte Black In-Channel Rain Guards

The WeatherTech 81942IMB are precision-crafted rear side window deflectors in a bold Matte Black finish, designed specifically for the GMC Terrain and Terrain Denali. These in-channel rain guards allow you to crack your windows open for fresh air ventilation without letting in rain, snow, wind noise, or debris — even in inclement weather.

Key Features:

• Matte Black Opaque Finish — Delivers a darker, non-transparent look for a distinctive, blacked-out aesthetic that complements modern styling
• In-Channel Installation — Installs securely inside the window channel with no exterior tape required, eliminating the risk of adhesive damage to paint or trim
• Aerospace-Grade Acrylic Construction — Built from impact-resistant acrylic material engineered to resist chipping, shattering, and UV damage for long-lasting durability
• Precision-Machined Fit — Custom-designed to match the exact contours of the GMC Terrain / Terrain Denali for a snug, rattle-free, OEM-quality appearance
• Reduces Wind Noise — Low-profile aerodynamic design deflects wind noise while keeping the interior dry and comfortable
• Fog and Heat Reduction — Promotes air circulation inside the cabin, helping prevent window fogging and reducing reliance on air conditioning
• Upholstery Protection — Shields the interior from water splashes, staining, and mold when windows are cracked open
• Designed and Engineered in the USA, Made in Germany

This listing covers the Rear Pair (driver and passenger rear windows). WeatherTech side window deflectors are also available in a Dark Tint finish and as a full front and rear set. MPN: 81942IMB.
