South Africa have retained the team that crushed Argentina by 60 points last weekend for the return Rugby Championship match in Mendoza on Saturday.
Coach Heyneke Meyer had no choice but to give a vote of confidence to the team that far exceeded expectations with a nine-try 73-13 first-round romp in Soweto.
There is one enforced change among the eight replacements with scrum-half Jano Vermaak replacing club-tied Fourie du Preez.
Du Preez, who came off the bench last weekend after a two-year Test absence, plays in Japan and is available only for the three home Tests.
The Springboks host Australia and world champions New Zealand in late September and early October.
Assuming reserve hooker Bismarck du Plessis comes off the bench in Mendoza, he will join 23 other Springboks to reach the 50-cap mark.
"It will be a special day for Bismarck and a well-deserved honour," coach Heyneke Meyer said in a statement released Wednesday.
"He has always given 100 percent for the Springboks and will do down in history as one of the best hookers to play the game.
"We are in a very privileged position to have two of the best hookers in world rugby in Bismarck and Adriaan Strauss.
"They bring out the best in each other and will continue to grow as players and leaders in the team."
After several seasons as understudy to now retired Springboks skipper John Smit, du Plessis's hopes of becoming a permanent starter were dashed by a long-term injury.
But the outstanding form of Strauss in the set pieces and loose exchanges has meant du Plessis starting on the bench.
Meyer warned that the Soweto rout is now history and he expects the crowd in western city of Mendoza to stir the shell-shocked Argentinians.
"We experienced first hand how passionate their supporters are last year, and how they can lift the Pumas," said Meyer.
South Africa were lucky to get a 16-16 draw thanks to a breakaway try after being outplayed for most of the international.
The Springboks have won seven other Tests in Argentina since 1993, with a 39-7 victory seven years ago in Buenos Aires the biggest victory margin.
