The club's performance was unremarkable in the years leading up to World War II, but improved after 1939. They captured the Gauliga Südwest/Staffel Saarpfalz title, but lost the overall division title to Staffel Mainhessen winners Kickers Offenbach. In the 1941–42 season the Gauliga Südwest was split into the Gauliga Hessen-Nassau and the Gauliga Westmark, and Kaiserslautern took the Westmark title, going on to play for the first time in the national final rounds. They were decisively put out 3–9 by eventual champions Schalke 04, the dominant side in this era of German football.
