RAM Level Cup 16oz Drink Holder with RAM Twist-Lock Suction Cup Base
The suction-mount version of RAM's self-leveling drink holder -- for a windshield, dashboard, or any other smooth surface where there is no rail or bar to clamp onto.
Why choose suction over a claw clamp
RAM sells the Level Cup on several different bases; this one uses the same 3.3" Twist-Lock suction cup as the phone mounts on this page, mounted through a B Size double socket arm. It is the right choice when there is no rail, roll bar, or edge nearby to clamp onto -- a passenger-side dashboard or a flat interior wall, for instance -- but a genuinely smooth, non-porous surface is available instead.
Features
- Self-leveling, gyroscopic drink holder keeps cups, cans, bottles, or mugs from 2.5" to 3.5" in diameter upright and spill-free
- 3.3" Twist-Lock suction cup base with B Size double socket arm; ball-and-socket joint allows near-infinite tilt and rotation
- Integrated tether eyelet and hook, useful for open or small containers
- Made of marine-grade aluminum and high-strength composite
How RAM's modular system works
Every RAM mount is built from up to three parts that click together. A base clamps, bolts, or straps onto the vehicle -- a dash, a windshield, a cup holder, or a rail. An arm connects two RAM balls together and can be locked at any angle, so once mounted you can tilt, rotate, and reposition the device freely, then lock it firmly in place by hand. A cradle or holder grips the specific device -- phone, tablet, or drink.
Not every product includes all three parts -- some are just the base, some bundle a holder, some are a complete kit. This page says plainly which parts are included with this particular SKU, so you know exactly what you are getting and what, if anything, you would need to add.
The ball size determines what it can carry
RAM uses five ball sizes, each rated for a different weight and duty class. This product uses B Size -- the ball size used on all six mounts in this line. B Size (part numbers starting RAM-B-...) is RAM's most common size, standard duty -- what RAM recommends for phones, GPS units, and light tablets in normal use. C Size (plain RAM-... part numbers, no letter prefix) is heavy duty, used for larger tablets and anything mounted somewhere that gets a lot of vibration or shock. D and E Size are reserved for large monitors and specialist equipment.
Rule of thumb: if the mount will live somewhere frequently jostled or vibrated -- an off-road vehicle, a gravel road at speed -- RAM recommends stepping up to a larger ball size for extra stability, even if a lighter mount would technically hold the device's weight.
No tools required, on purpose
RAM arms are designed to be tightened by hand only -- there is no official torque spec, because the ball-and-socket joint is meant to be adjustable in the field without a wrench. If hand-tightening does not hold your device firmly, that is usually a sign the ball size is undersized for the device -- sizing up solves it, rather than over-tightening.
Aluminum or composite -- both built for the outdoors
RAM mounts are made from marine-grade aluminum or high-strength composite, depending on the product; both carry a lifetime warranty and similar weight ratings. Aluminum's powder-coat finish handles rough vibration and shock slightly better; composite has no paint to chip and is often preferred in high-corrosion or salt-air environments. Neither choice is worse -- it is a trade-off between finish and environment.

Frequently asked questions
Does this damage the windshield or dashboard?
No. It holds by vacuum against smooth glass or polished, non-porous plastic -- no adhesive, no screws, no marks.
How strong is the grip over time and temperature swings?
Rated for repeated daily use; large temperature swings can affect the seal, in which case wiping away condensation and re-engaging the locking lever restores the hold. The rubber cup is a wear item and, like any suction mount, is not covered by the lifetime warranty on the mount hardware.
Would a standard soda can fit snugly?
A standard can is about 2.1" in diameter, and this holder fits anything from 2.5" to 3.5" -- so a bare can will sit a bit loose. The included koozie insert takes up the extra space for a snugger fit.
Is drilling required?
No. The suction cup base is entirely tool-free.
Is the double socket arm and suction cup included, or sold separately?
Both are included in this kit -- the double socket arm and the Twist-Lock suction base ship together with the Level Cup holder.
