What customers say
Customers overwhelmingly praise the RAM Mount for its exceptional reliability and superior build quality. The twist-lock suction cup mechanism consistently maintains a secure grip, even during harsh driving or extended trips, offering true set it and forget it peace of mind for navigation needs. Users value the system's inherent modularity, allowing easy integration with various arms and holders, making it a versatile investment. While the premium price is justified by the stability and longevity, users note that maximum suction requires a very clean, nonporous surface like glass. Overall, the mount delivers outstanding performance and long term security for serious users.
Know before you buy
Yes, the 3.3-inch suction cup is designed to adhere to smooth, non-porous surfaces. While it is optimized for windshields, it can also be used on a dashboard if the surface is flat, smooth, and clean, or in conjunction with a compatible RAM friction base.
The mount features a patented 1-inch rubber ball and socket system that acts as a dampener to absorb shock and vibration. This design significantly reduces stress on your device, making it suitable for off-road or bumpy driving conditions.
The RAM-B-166-LO4U is specifically configured for certain Lowrance units, but the 1-inch ball and socket system is part of the modular RAM ecosystem. You can swap out the cradle or adapter to fit a wide variety of other GPS units, phones, or handheld devices.
No, the twist-lock suction cup is designed for tool-free installation. You simply place the cup against the surface and rotate the locking mechanism to create a secure vacuum seal.
The mount is crafted from powder-coated, marine-grade aluminum, which is highly resistant to corrosion and wear. This material choice ensures the mount remains rigid and reliable even in extreme temperatures or harsh environments.
Yes, the double socket arm allows for infinite adjustment. By loosening the side knob, you can pivot the ball joints to position your device at the exact angle you need, then tighten the knob to lock it securely in place.
