The Jaguares announced on Monday that they have retained six key players until the 2019 World Cup.
Matías Alemanno, Emiliano Boffelli, Santiago García Botta, Mark Kremer, Pablo Matera and Guido Petti have all extended their contracts with the Argentinean franchise.
Jaguares board member Fernando Rizzi said he was ecstatic that the side could keep hold of the players.
"It is a great joy for us to have these talented young players for the next three seasons, which will be demanding and very important to further develop our rugby in Super Rugby as we strive for excellence and professionalism," Rizzi told the Jaguares website.
Jaguares flanker Pablo Matera says that he wants to use this opportunity to turn their fortunes around after a disappointing 2016.
"I have wanted to play in this tournament. While it was our first time, I want to continue playing in it because last year we did not go as well as we wanted to," Matera said.
"We are learning a lot but there is still a lot to learn from this type of rugby and that's why I want to carry on playing in it until the World Cup. Going to Japan 2019 is also a huge incentive for a player, of course."
Argentinean international Santiago García Botta added: "It was a very personal and important decision. As I believe in this project. The rugby that we have the opportunity to play is the best rugby in the world and we want to continue growing as players, it is the best opportunity.
"And of course, to continue to have the opportunity to play for the Pumas."
