The plural form “are” is correct here.

Since two things are dropping, both “size” and “cost”, then those things “are” dropping.

Eliminate “of parts,” which is a modifier and try the simplified version; “The size and cost are dropping.”

However, I am not sure what “the size of parts is dropping” would mean. Those particular parts are being made in smaller sizes ?

In English make sure verbs and subjects agree – singular subjects have singular verbs and plural subjects have plural verbs. Sentences with two subjects joined by and take a plural verb, even if each of the two subjects is singular.

You could rephrase it. ‘Parts are getting smaller and cheaper” for example.
