This A-Tach Chevrolet Silverado and GMC Sierra phone mount solution consists of two separate parts that are brought together to create a secure mounting solution. The first part is the vehicle mount which is designed specifically for the listed Chevrolet Silverado and GMC Sierra models. The mount comes with four small, predrilled holes in an AMPS hole pattern and can be used with many brands of phone holders.

The second part is a phone holder or device holder. A phone holder is not included when purchasing the mount only. See the "Device Holder Options" tab for some great device holder choices.

Why do customers purchase a vehicle specific Chevrolet Silverado / GMC Sierra phone mount from A-Tach?

Customers opt for vehicle-specific phone mounts designed for the Chevrolet Silverado / GMC Sierra models primarily for enhanced safety, durability, and seamless integration tailored to the truck's rugged design and dashboard layout. A-Tach mounts outperform generic options like vent clips or suction cups, which often fail on bumpy roads or in off-road conditions common to Silverado owners. Below is a breakdown of the key reasons:

Perfect Fit and Easy, Damage-Free Installation

A-Tach mounts are precision-engineered using machine tooling to match the contours of the Silverado's dashboard (e.g., for 2019–2025 models with 7–13.4-inch touchscreens). This ensures a custom, OEM-like fit without drilling and adhesives that leave residue, or modifications.
Why it matters: Generic mounts wobble, sag, or fall off, leading to frustration. Users report returning multiple universal options before switching to A-Tach Silverado-specific ones. Installation typically takes under 5 minutes with no tools and remove cleanly without marks to help with a higher resale of the vehicle.

Superior Stability and Durability for Rugged Use

Constructed from high-quality materials like rugged ABS Plastic, these mounts withstand vibrations from rough terrain, 4x4 trails, or heavy-duty hauling—ideal for the Silverado's workhorse nature.
Why it matters: Silverado drivers need a mount that holds firm during off-road or long-haul trips, preventing phone drops that could distract or damage devices. Include an A-Tach Holder with ball-socket joints to provide 360° adjustability without loosening.

Improved Safety and Optimal Viewing Position

Positioned on the dash for optimal viewing, they keep the phone at eye level for hands-free navigation, calls, or GPS without blocking the windshield, controls, or airflow.
Why it matters: This reduces distractions and complies with hands-free driving laws. Users note it allows quick glances with hands on the wheel—crucial for daily commuters.

Aesthetic and Functional Integration

Sleek, low-profile designs blend with the Silverado's interior, in black finish that match trim levels (e.g., High Country or WT). Holder options include MagSafe compatibility, wireless charging, or multi-device support (e.g., for GPS devices).
Why it matters: Truck owners value a clean, professional look that doesn't clutter the cab. It's a worthwhile upgrade over "flimsy" generics.

In summary, A-Tach mounts address the Silverado's / Sierra’s unique demands for reliability in demanding environments, turning a common frustration into a seamless enhancement.

Visually inspect your dash for a match to our photos due to model year styling changes in different markets. Contact us if you have any questions. Also, check to see how the device will fit the location or could affect other vehicle operations. This A-Tach vehicle mount is custom designed to fit in the location illustrated in the photo and additional photos. A-Tach provides photos of where the mount will attach onto the vehicle. A-Tach cannot know, however, if your specific device will fit in the location illustrated. The customer or intended user has both the vehicle and device and is the best person to determine most accurately if the mount is correct for the dash and if the specific device will fit and work where the mount is shown in the photo.
