How RAM ball sizes work

Every RAM mount is rated for a ball size that determines what it can carry and where it belongs -- from small security cameras up to heavy tablets in a vibrating ATV cab. This short official RAM Mounts video explains the five ball sizes and their weight capacities.

Frequently asked questions

Do all RAM mounts fit together?
Any two parts with the same ball size click together -- a base from one product line and an arm or holder from another. The finder above always recommends a matching combination, but if you're building your own, keep the ball size (B, C, etc.) consistent across the base, arm, and holder.

I don't see my exact vehicle or device -- what do I do?
Our curated range covers the most common tractor, ATV/UTV, motorcycle, car, and truck setups plus GDS Uni-Conn docking. RAM Mounts makes thousands of SKUs beyond what we stock -- contact us with your vehicle and device and we'll check what fits and order it in.

Can I mount a tablet or phone in more than one vehicle?
Yes -- if the device moves between an ATV cab and a truck, for example, RAM's GDS Uni-Conn docking system (see the Uni-Conn option above) is built exactly for that: one IntelliSkin case per device, one dock or holder per location.

Does RoboService install these?
Most RAM mounts are a straightforward bolt-on or clamp-on installation you can do yourself in a few minutes. Contact us if you'd like help specifying or fitting a mount for your fleet.
