  The Proton Improvement Plan-II (PIP-II [1]) linac will include 35 Single
Spoke Resonators type 2 (SSR2). A preproduction SSR2 cryomodule will contain 5
jacketed cavities. Several units are already manufactured and prepared for cold
testing. In this work, data collected from the fabrication, processing and
preparation of the cavities will be presented and the improvements implemented
after the completion of the first unit will be highlighted.
