6 Best Modular Mounting Arms For Overland Vehicle Rigs

Navigating a rugged backcountry trail requires split-second access to GPS mapping, communication devices, and vehicle vitals. A loose tablet or a rattling phone mount is more than just a nuisance; it is a distraction that compromises focus on technical terrain. Reliable modular mounting systems transform a chaotic dashboard into an intuitive command center, ensuring essential data stays exactly where it belongs when the trail gets rough.

RAM Mounts Tough-Claw Arm: Best Overall Pick

The RAM Mounts Tough-Claw remains the industry standard for a reason, offering an unmatched balance of accessibility and rock-solid stability. Its tool-free installation makes it ideal for adventurers who rent vehicles or swap gear between a daily driver and an overland rig.

The ball-and-socket system allows for infinite adjustment, meaning a screen can be tilted to eliminate sun glare or repositioned for a co-pilot to manage navigation. While the composite construction might lack the high-end aesthetic of carbon fiber, the durability in dusty, vibrating, or high-heat environments is legendary.

Choose the Tough-Claw if the priority is versatility and field-repairability. It is the perfect entry point for those who want a reliable, modular system without committing to a permanent dashboard modification.

67 Designs Carbon Fiber Arm: Top Heavy Gear Pick

When running heavy tablets or oversized diagnostic monitors, traditional plastic mounts often suffer from “arm droop” on washboard roads. The 67 Designs carbon fiber arm solves this by combining rigid, lightweight materials with precision-machined aluminum joints.

This system is specifically engineered for serious overlanders who utilize heavy-duty electronic tablets for high-resolution topographical mapping. The carbon fiber dampens vibration more effectively than metal-only arms, preventing screen jitter during long stints on corrugated gravel.

This mount is a premium investment for those who value weight reduction and structural rigidity. If the navigation setup involves a large-format screen, this system offers the structural integrity necessary to prevent hardware failure.

Bulletpoint RubiGrid Arm: Best For Multi-Device

Dashboard real estate is finite, yet modern overland rigs often demand multiple screens for GPS, satellite communicators, and accessory controllers. The Bulletpoint RubiGrid creates a dedicated, vehicle-specific mounting platform that replaces unsightly suction cups with a clean, factory-integrated look.

The modular nature of the grid allows for precise positioning of several devices side-by-side without them competing for space. It turns a cluttered dash into a professional-grade flight deck, ensuring that critical info is visible at a glance without obstructing the windshield.

This is the definitive choice for the tech-heavy builder who values organization above all else. It is an excellent solution for those tired of suction cup failure and permanent adhesive residue on their interior trim.

Tackform Enterprise Series: Most Durable Metal

For those who prioritize raw durability over weight savings, the Tackform Enterprise series is constructed from CNC-machined aluminum. These mounts are built to withstand the physical abuse of aggressive rock crawling and high-speed desert crossings.

The locking mechanisms on these arms are exceptionally tactile, providing a confident “clamping” feel that ensures the arm stays exactly where it is locked. The metal-on-metal design effectively eliminates the creeping that occurs when plastic components eventually fatigue under constant load.

This mount is ideal for the driver who pushes their vehicle to the limit and demands gear that is practically indestructible. If the budget allows for a “buy once, cry once” approach to equipment, this is the hardware to choose.

Quad Lock 360 Mounting Arm: Best Phone Security

The Quad Lock 360 system is unique because it utilizes a dual-stage locking mechanism rather than a traditional clamp. This physical interface locks the phone directly to the arm, virtually eliminating the risk of a device ejecting during a high-impact jolts or unexpected drops.

This system is perfect for riders who occasionally switch between an overland rig, a motorcycle, or even a mountain bike. The ecosystem of accessories allows a phone to transition from the dashboard to a handlebar mount in seconds.

Choose this setup if the absolute security of the device is the primary concern. It is the most reliable way to ensure a phone stays locked in place, regardless of how jarring the trail becomes.

Rokform Heavy Duty Universal: Best Low Profile

Not every trail setup needs a long, articulated arm, and in smaller cockpits, large mounts can feel intrusive. The Rokform Heavy Duty Universal mount provides a slim, minimalist footprint that keeps the dashboard clear while still offering a secure magnetic and mechanical lock.

The low-profile design minimizes leverage, meaning there is less vibration transfer to the device itself. It is a discreet solution for drivers who want to keep their navigation tech tucked neatly out of the primary line of sight.

This is the right choice for the minimalist who values interior aesthetics as much as utility. It performs best in environments where space is at a premium and a bulky arm would be more of a hindrance than a help.

How to Choose the Right Modular Mount for Your Rig

Selecting a mount requires assessing the specific “chassis” of the vehicle and the weight of the intended hardware. Larger, heavier tablets require a system with a wider ball-diameter or reinforced arms to prevent vibration, while lightweight phones can utilize more compact, agile options.

Consider the degree of articulation required for the environment. If the vehicle has a steep windshield rake, a longer arm is necessary to pull the device into a usable position.

Always account for the mounting surface. If the dashboard is textured or lacks flat sections, a vehicle-specific base or a rigid grid system is mandatory to ensure a secure, long-term foundation.

Essential Tips for Securing Devices on Rough Trails

The most common failure point in any mounting system is not the arm itself, but the vibration transmitted through the mounting base. Periodically checking the tension of every bolt and ball-joint is a necessary ritual before any multi-day expedition.

Use tethering systems for high-stakes equipment like dedicated GPS units or expensive tablets. A thin, braided steel lanyard attached to a secure dash point provides a final fail-safe if the primary mount ever reaches its fatigue limit.

Avoid over-tightening plastic components, as heat cycles and trail vibration can cause these materials to crack under excess stress. Instead, opt for metal components when expecting long-term, high-intensity use on harsh terrain.

Managing Dashboard Clutter: Layouts and Strategies

Organization on the dashboard should follow a hierarchy of information needs. Primary navigation devices should occupy the center line of sight, while auxiliary gear like comms or auxiliary switch controllers should sit toward the periphery.

Avoid placing any screen in a position that forces the eyes away from the road for more than a second. If multiple devices are necessary, stack them vertically if space allows, keeping the most critical data at the top of the stack.

Strategically route cables before final installation to prevent tangles that can snag on gear or passengers. Use cable clips or adhesive channels to keep power lines flush against the dash, ensuring a clean and professional cockpit setup.

Care and Maintenance: Keep Mounts Tight Over Time

Exposure to extreme UV radiation, freezing temperatures, and constant vibration will eventually loosen even the best hardware. Implement a “pre-trip inspection” where every adjustment knob is backed off and tightened to ensure the threads haven’t seized.

Clean the ball-and-socket interfaces with a dry cloth periodically to remove fine trail dust. Grit inside these joints acts like sandpaper, causing premature wear and reducing the effective locking force of the mount.

If a mount feels sluggish or won’t hold its position, avoid using lubricants on the ball itself, as this can cause the device to slip. Replace worn rubber washers or composite inserts regularly to maintain the high-friction interface required for rock-steady performance.

Equipping a vehicle with the right modular mounting system turns an otherwise daunting trail into a well-informed adventure. By choosing hardware that matches the intensity of the terrain and the weight of the gear, the focus can remain where it belongs: on the horizon. Secure the setup, plan the route, and get outside.
