Rugged Radios RAM Stubby Cup Holder Ball Base
The RAM Stubby Cup Holder Ball Base provides a secure, low-profile mounting solution designed to fit directly into standard vehicle cup holders. It offers a stable foundation for mounting radios, GPS units, or other mobile devices inside cars, trucks, UTVs, and off-road vehicles.
Constructed for long-term reliability, this base features a durable composite build and flexible support fins that adapt to different cup holder sizes. It integrates seamlessly with the proven RAM ball-and-socket system, allowing smooth positioning and adjustment to achieve your preferred viewing or operating angle.
Ideal for both daily driving and rugged outdoor use, this compact mount eliminates the need for permanent drilling or adhesive installation. It offers a portable, easy-to-set-up solution that works across a wide range of vehicle interiors.
Features
- Low-Profile Design: Compact construction for minimal obstruction in vehicle interiors
- Adjustable Fit: Flexible support fins can be trimmed to match cup holder dimensions
- RAM Ball Interface: Built-in 1” B-size rubber ball works with all compatible RAM mounting arms
- Durable Build: Made from high-strength composite materials for lasting performance
- Portable Installation: No tools or permanent modifications required
Construction & Materials
The base is molded from high-strength composite material, chosen for its resistance to vibration, temperature changes, and general wear. The flexible support fins securely grip the interior of the cup holder, preventing movement during travel over rough roads or trails.
The integrated rubber ball is engineered to reduce vibration transfer, keeping devices stable even in bumpy conditions. This design ensures consistent performance across both light and heavy use scenarios.
Fitment & Compatibility
Designed to fit most standard vehicle cup holders, the base accommodates inner diameters ranging from 2.57” to 3.5”. It is compatible with any B-size RAM double socket arm and accessory cradle, giving you full flexibility to build a custom mounting setup.
Specifications
- Ball Size: 1” B-size rubber ball
- Overall Height: 4.9 inches
- Weight Capacity: 2 lbs standard use / 1 lb heavy-duty use
- Weight: 1.13 lbs
Installation & Usability
Installation is quick and straightforward: simply insert the base into the cup holder and adjust the fins until it sits firmly. If needed, the fins can be carefully trimmed to achieve a tighter fit in smaller holders. Once secured, attach your chosen RAM arm and device holder to begin using the mount.
The ball-and-socket system allows nearly unlimited rotation and positioning, letting you angle your device exactly where it is most visible and accessible.
Why It Stands Out
This mount combines versatility, strength, and ease of use into a compact form factor. Unlike permanent dash or window mounts, it is fully removable and transferable between different vehicles, making it a practical choice for anyone who uses multiple vehicles or prefers non-invasive installation.
Backed by the trusted RAM mounting system, it delivers reliable performance in both everyday commuting and demanding off-road environments.
Application
- Handheld radios and mobile communication devices
