Ball Size Showdown: 1-Inch vs. 20mm Explained

The choice between a 1-inch ball and a 20mm ball often comes down to the intended use and device weight. 1-inch systems, popularized by RAM, offer an immense range of compatibility due to their market dominance. They are versatile and easy to find, making them ideal for someone who frequently changes device setups or carries multiple accessories.

Conversely, 20mm systems have become the gold standard for modern, heavy-duty vehicle mounts. They provide a more compact footprint and are often machined to tighter tolerances, which helps eliminate vibration in high-impact scenarios. A 20mm system is generally the better choice for a dedicated, permanent dashboard mount in an off-road rig.

When deciding, consider the total weight of the device and the intensity of the driving. For a lightweight phone, a 1-inch ball is more than adequate. For a full-sized tablet or heavy navigation device in a rugged rig, the 20mm system provides the necessary leverage control for a stable, jitter-free experience.

Choosing the Right Arm for Your Rig and Device

• Long Arms: Use these when the mounting point is far from the driver’s reach, allowing for greater adjustability and reach.
• Short Arms: Opt for these to maximize stability, as they reduce the amount of flex and vibration possible between the base and the device.
• Double-Socket Arms: Choose these for maximum articulation, enabling precise angles that are crucial for cameras or dual-screen setups.

Every inch of length added to an articulating arm increases the potential for vibration. Aim for the shortest possible configuration that still allows for comfortable viewing and operation. If the rig is prone to heavy bouncing, prioritize a shorter arm to minimize the strain on the ball joint.

Assess the mounting surface before purchasing the arm. A thin, plastic dash trim will likely wobble regardless of the mount quality, while a solid steel mounting bar will maximize the mount’s potential. Always choose the arm length that prioritizes rigidity over reach.

Pro Installation Tips for a Rattle-Free Mount

Proper installation is just as important as the quality of the hardware. Always use a dedicated cleaning agent to remove any grease or wax from the mounting surface before applying adhesive or base plates. A clean surface is the single most important factor in preventing the mount from loosening over time.

Ensure that all connection points are tightened incrementally. After the initial install, perform a “shakedown run” on a bumpy road, then re-tighten every nut and bolt. Vibrations have a way of loosening even the most robust systems, so a follow-up tightening session is mandatory for long-term security.

Consider using thread-locking fluid on permanent mounting screws to prevent them from backing out due to vehicle vibration. This simple step can save a mount from failure in the middle of a remote transit. When in doubt, a little extra attention during installation goes a long way toward a rattle-free journey.

How to Maintain Your Mounts for Rough Trails

Periodic maintenance ensures that the articulating arms continue to hold their position throughout the lifespan of the vehicle. Dust and fine trail grit can accumulate in the ball-and-socket joint, acting as a lubricant that causes the device to slip. Use a damp cloth to wipe down the balls and the inner sockets after every long, dusty trip.

Avoid using chemical lubricants on the ball joints, as these will cause the arm to slip rather than provide the necessary friction. If the connection feels loose, it is usually a sign that the joint needs a thorough cleaning rather than tightening. A clean surface provides the best grip for the rubberized or metal components.

Finally, inspect the mounting hardware for signs of stress or fatigue before heading out on a major expedition. If a bolt shows signs of rounding or the aluminum starts to show fatigue, replace the component immediately. Keeping the gear in prime condition ensures the rig remains ready for whatever the terrain demands.

Selecting the right mounting system is an investment in your focus and your ability to navigate safely through the wilderness. By choosing a solution that matches your rig’s intensity and your device’s needs, you ensure that your gear works for you rather than against you. Now that the cockpit is properly equipped, it is time to turn the key, hit the trail, and see where the journey leads.
