RAM Ball Sizes
I stock 2 sizes are RAM parts.  The A size parts use 9/16 inch (14.3 mm) diameter balls and the B size parts use 1 inch (25.4 mm) balls.  Be careful to select all A or B sized components when you order because A size balls will not fit in B size arm ends, etc.

More Mount Parts Available
RAM has a huge variety of mounting accessories for many GPSs and PDAs.  While I do have a sizeable inventory of RAM parts, I don't stock all of them.  But I can get any RAM part.  Just let me know what you need, and I'll get it for you.

What Does the "U" in the part number mean?
The "U" at or near the end of the part number stands for "unpackaged". The parts are delivered in a simply plastic bag - rather than in more expensive plastic store display boxes. I stock and sell only the unpackaged (plastic bag packaged) parts because they are less expensive. Note that assembly part numbers do not end in "U", but they do contain parts that are provided in plastic bags rather than store display boxes.
