Your Phone Mount Should Survive the Same Roads You Do
The ToughTested Mammoth Windshield & Dash Phone Mount is a windshield and dashboard mount built for trucks, fleet vehicles, and work rigs. It's for drivers who need their phone visible and locked in on roads that rattle everything loose.
Most phone mounts hold fine on smooth pavement. Hit gravel, a highway seam, or a job-site entrance, and the arm goes slack. The mount becomes one more thing you're managing while you're trying to drive.
The ToughTested Mammoth is engineered at every joint — base, gooseneck, and grip — to hold up where other mounts give out.
4-Inch Suction Cup for Windshield and Dash Mounting
The suction cup measures 4 inches in diameter — larger than the 2-to-3-inch cups on most consumer mounts. More surface area means more holding force against glass or a smooth dash panel. It locks down and stays locked, even when the cab heats up on a long summer haul.
The Mammoth mounts to both windshield glass and smooth dashboard surfaces. Two placement options, one mount. Put it where your phone stays in reach without blocking your sightlines.
Double-Ribbed Gooseneck Holds Its Angle Under Vibration
The gooseneck is the weak point on most adjustable mounts. A single-ribbed neck feels stiff in the store and goes floppy after a few months of daily vibration. The ToughTested Mammoth uses a double-ribbed gooseneck that resists constant movement.
Set your viewing angle once. It stays through potholes, highway miles, and rough job-site roads. No repositioning on the fly.
4-Way Grip, 360-Degree Rotation, Built to Reduce Vibration
The device grip expands in four directions to fit your phone with or without a case. Rotate 360 degrees to set portrait or landscape, then leave it. The Mammoth doesn't need to be reset every time you get back in the cab.
The entire mount — base, neck, and grip — is built to absorb vibration rather than transmit it. That engineering choice is what separates this from a mount that just looks solid in the store.
