1967–2003: Beginnings
The Selangor State Development Corporation () (PKNS) have been involved in the sporting arena since 1967 through the establishment of its Sports and Recreation Club within the organization for their staff to be involved in sports and recreational activities. The PKNS Sports and Recreation Club football team had its own staff as footballers in the early stages. The football team made its name between the 1970s to 1980s as one of the forces in the state of Selangor that competed in the Selangor League at state-level and the Malaysia FAM Cup at the national level with famous players like Mokhtar Dahari, R. Arumugam, K. Rajagopal, Reduan Abdullah and Santokh Singh, who also served as PKNS' staff. The Malaysia FAM Cup was opened to club teams from 1974 onwards while the Malaysia Cup was restricted to state teams, but some PKNS players appeared in both competitions.
The club's involvement in football has seen many achievements. The club has produced a number of football players that not only succeeded at club level but also at state, national and international levels. Their routine was to work in the day and in the evening to practice for the company football club to play in state league and Malaysia FAM Cup games, with the possibility of also playing for the state of Selangor in the Malaysia Cup. PKNS' Sport and Recreational Club first won the Malaysia FAM Cup together with Negeri Sembilan Indians in 1978 after both teams were tied 0-0.
