CMVT Auto Window Visors for Silverado/Sierra Double Cab (Dark Smoke) — Tape-On In-Channel Rain Guards, 4-Piece Set

CMVT Auto in-channel rain guards are dark-smoke, tape-on window visors custom-shaped for 2014–2018 Silverado 1500 and compatible 2015–2019 Silverado/Sierra heavy-duty Double Cabs to let fresh air in while keeping rain and wind out.

These vent deflectors are molded from reinforced acrylic and engineered to match the factory window contours on specified Chevy and GMC Double Cab models. They install using an in-channel, tape-on method and are designed to lower cabin wind noise, reduce side-mirror and window fogging, and allow ventilation even when it’s raining. The set includes four pieces sized for the two full-size front doors and two half-size rear doors.

Will these fit my Silverado or Sierra double cab precisely?

Yes — each visor is cut and curved to align with the factory window opening of the listed model years. Fitment covers 2014–2018 Chevrolet Silverado 1500 Double/Extended Cab, 2015–2019 Silverado 2500HD and 3500HD Double Cab, 2014–2018 GMC Sierra 1500 Double Cab, 2015–2019 Sierra 2500HD/3500HD Double Cab, and a selection of 2019 Silverado/Sierra variants.

• Includes 2 full-size front and 2 half-size rear visors for Double Cab doors.
• Designed to match OEM window curves for the specified model years.
• Check model year and cab type before installation to confirm match.

How durable and weather-resistant are these window visors?

Constructed from modified acrylic, the visors resist cracking, chipping, and deformation from typical road and weather exposure. The dark smoke finish provides UV resistance and a factory-like appearance while maintaining clarity and structural integrity over time.

• Modified acrylic material resists impacts and temperature changes.
• Dark-smoke tint reduces glare and preserves cabin privacy.
• Edges and contours engineered to minimize water infiltration.

How are these rain guards installed and maintained?

Installation uses an in-channel tape-on method that holds the visors securely inside the window channel. For best adhesion, heat the mounting edge with a heat gun or hair dryer after positioning—this helps the tape conform, especially in colder weather. Clean the channel thoroughly and dry it before applying the visor; test-fit first before final adhesion.

• Test-fit visors before removing protective backing from tape.
• Use heat on the mounting edge to improve tape bond when installing.
• Wipe channel clean and let dry; avoid car washes for 24–48 hours after install.

What practical benefits should I expect from these vent deflectors?

These visors let you crack windows for ventilation without allowing rain to enter, which helps reduce interior humidity, fogging, and stale air. They also smooth airflow around the side windows to lower wind buffeting at highway speeds and can help maintain clearer side mirrors by directing water away.

• Permits partial window opening during rain for fresh air exchange.
• Helps reduce interior wind noise and mirror fogging in wet conditions.
• Provides a subtle styling upgrade with dark-smoke tint.

Who this is for: motorists who drive 2014–2019 Chevy or GMC Double Cab trucks and want a practical, low-profile upgrade that improves ventilation and weather protection without drilling or permanent modification. Ideal for owners who park outdoors, drive in rainy climates, or want to reduce cabin condensation while preserving the vehicle’s factory lines. CMVT Auto backs the product with a one-year warranty and customer support for fitment or installation questions.
