The club's greatest success has been to earn promotion to the tier four Regionalliga West in 2012, and again in 2014.

FC Kray played in the tier four Verbandsliga Niederrhein from 1989 to 1993 before dropping back to the Landesliga.

In 2010–11 the club won a somewhat surprising Landesliga championship and finally returned to the Verbandsliga.

FC Kray won this league in its first season back and would have normally been promoted to the Oberliga.

However, changes to the German football league system at the end of this season meant that the club jumped instantly from the sixth to the fourth tier and entered the Regionalliga West for 2012–13 instead.
