RAM MOUNTS Level Cup Self-Leveling Drink Holder — Medium B-Size Arm, Fits 2.5"–3.5" with Foam Koozie

RAM MOUNTS Level Cup is a self-leveling drink holder that secures cups, cans, bottles and mugs while preventing spills on motorcycles, ATVs, boats and other vehicles.

Designed for riders and boaters who need a stable, adjustable cup holder, this RAM MOUNTS assembly combines a self-leveling cradle with a B-size 1" rubber ball and medium double-socket arm for broad mounting flexibility. It adapts to containers 2.5"–3.5" in diameter and includes a foam koozie to fit slimmer drinks and minimize rattling. Built from materials meant to endure motion and outdoor conditions, the system gives you a convenient beverage solution that stays secure as you move.

How does the self-leveling design reduce spills?

The cup cradle pivots independently from the mounting arm so the drink remains upright even when your vehicle tilts or rocks. This mechanical leveling absorbs sudden angles and small bumps, helping liquids stay inside the container instead of sloshing out. It’s a passive solution—no adjustments needed once you place a drink in the holder.

• Self-aligning cup cradle keeps beverages upright during motion
• Pivots smoothly to compensate for leaning and rocking
• Works continuously without manual intervention

What sizes and bottle types does it fit?

The holder accepts a wide range of common drink sizes from 2.5" to 3.5" in diameter, covering many cans, travel mugs and bottles. A supplied foam koozie slips around slimmer containers to improve fit and reduce vibration. For oversized tumblers or very narrow bottles, optional adapters or different RAM cups may be better suited.

• Compatible with cups, cans, bottles and mugs 2.5"–3.5" diameter
• Includes a foam koozie for narrower drinks
• Works with most standard travel mugs and soda cans

How do I mount and adjust the B-size arm?

The kit includes a B-size 1" RAM rubber ball and medium-length double socket arm that locks between a ball base and the cup cradle. Tightening the socket knobs secures the arm in the position you choose, and loosening them allows near-infinite adjustment for reach and angle. The modular RAM system also makes it easy to swap arms or bases for different mounting locations.

• Includes B-size 1" rubber ball compatible with RAM accessories
• Medium double-socket arm provides broad adjustable range
• Knobs lock position quickly for a secure hold

What environments and activities is this holder built for?

Constructed for on-the-go use, the holder performs well on motorcycles, ATVs, boats, and other outdoor vehicles where motion and vibration are common. Materials resist everyday exposure and the cup cradle secures drinks during bumps, turns and choppy water. While designed for rugged conditions, periodic checks of fasteners are advised for long-term reliability.

• Ideal for motorcycles, ATVs, boats and outdoor vehicles
• Durable construction for frequent vibration and movement
• Recommended regular checks of knobs and mounts for safety

Who is this for? Riders, off-road adventurers and boaters who want a dependable, adjustable drink holder that minimizes spills and adapts to different mount points will benefit most. It’s also suitable for anyone already using RAM ball-and-socket components who needs an easy-to-position cup solution. If you want a low-maintenance, modular holder that integrates with RAM mounting hardware and accepts a wide variety of drinkware, this self-leveling cup system is a practical choice.
