Learn how to pick the right RAM VESA mount for your truck or mobile setup. Compare double ball arms, pedestals, and pole mounts for 75x75mm monitors.
Quick Answer
For a stable, adjustable monitor mount in a truck or mobile office, start with a RAM double ball arm and a 75x75mm VESA plate. Choose a long arm for larger monitors or a medium arm with a jam nut for vibration-prone vehicles.
Why a Double Ball Arm Works Best for Vehicles
Vehicle mounts face constant vibration, temperature changes, and occasional bumps. RAM's patented rubber ball and socket system absorbs shock while allowing you to tilt and swivel the screen. A double socket arm gives two adjustment points, so you can position the monitor exactly where you need it without tools.
The trade-off is that a double ball arm takes up more space than a fixed pedestal. If your cab is cramped, a shorter arm or a different base type may be a better fit.
Pedestal vs. Pole Mount: When to Choose Each
A pedestal mount like the 7-inch model works well on a desk or flat surface where you want the monitor to stand freely. It swivels 180 degrees and tilts 180 degrees, but it does not have the shock absorption of a ball-and-socket arm.
A pole mount, such as the 8-inch upper pole with a double ball arm, is designed for in-vehicle GDS systems. It lets you attach both a keyboard and a monitor, swinging the keyboard out of the way when not in use. This setup is more complex and costs more, but it is ideal for a full mobile workstation.
Decision Rules for Choosing a Vehicle VESA Mount
- Check your monitor's VESA pattern: Most small monitors use a 75x75mm pattern. Measure the distance between mounting holes on the back of your screen. If it is 75mm, any RAM VESA plate with that pattern will work. If it is 100mm, look for a plate that supports both patterns. Measure before you buy; the 75x75mm pattern is common but not universal.
- Choose arm length based on space and screen size: A long C-size arm (like on the RAM-101U-D-2461) provides more reach and articulation for larger monitors or when the mount point is behind the seat. A standard-length arm (like on the RAM-D-101U-MI1-2461) is more compact and stable for smaller cabs.
- Decide between a jam nut or a standard socket: If your vehicle travels on rough roads or off-road, choose a mount with a jam nut. It prevents the arm from loosening over time. For smooth highway driving, a standard double socket arm is sufficient and easier to adjust. Jam nut adds vibration resistance at the cost of tool-free adjustment.
- Consider the base mounting surface: RAM round bases with pre-drilled holes (two at 180° or three at 120°) let you bolt the mount securely to a flat surface. If you need to attach to a pole or roll cage, a pole mount like the 8-inch upper pole is the right choice. Match the base pattern to your vehicle's available mounting points.
Product Facts
- RAM® Double Ball Mount with 75x75mm VESA Plate - C Size Long: The RAM-101U-D-2461 uses a long double socket arm with a 2.5" round base and a 3.625" square VESA plate with a 75x75mm hole pattern. The long arm gives you extra reach and two adjustment points, making it a good choice for larger monitors or setups where the mounting point is far from the ideal viewing position.
RAM® Double Ball Mount with 75x75mm VESA Plate - C Size Long - RAM® Double Ball Mount with 75x75mm VESA Plate and Jam Nut - Medium: The RAM-D-101U-MI1-2461 has a 3.68" round base, a standard-length double socket arm with a jam nut, and a 75x75mm VESA plate. The jam nut locks the arm in place, reducing vibration and accidental movement, which is critical in off-road or heavy-duty truck environments.

Which Mount Fits Your Setup?
Best For
- Truck or van with a flat surface near the driver seat and a 75x75mm monitor
- Mobile workstation that needs a keyboard arm alongside the monitor
Not For
- Desk or home office where a simple fixed pedestal is sufficient
- Very small cabs where any arm would block the passenger seat
