Springbok coach Rudolf Straeuli has warned Wales that his side will be pumped up for the second Test at Newlands.
He has named a side showing four changes to the team that beat Wales 34-19 at Bloemfontein on Saturday.
Stormers hard man Quinton Davids and Corne Krige have been brought in to add extra muscle to South Africa's pack.
There are also two changes behind the scrum with inside centre De Wet Barry taking over from dropped Andre Snyman.
Meanwhile, Brent Russell moves to full back with Andre Pretorius reclaiming the fly-half spot.
"I don't have to say much about Krige coming back. Loubscher was injured and we are happy with Brent playing at full-back.
"De Wet Barry is an out-and-out inside centre and it's nice to have someone like Quinton starting on his home patch."
South Africa team: Brent Russell; Stefan Terblanche, Marius Joubert, De Wet Barry, Breyton Paulse; Andre Pretorius, Johannes Conradie; Daan Human, James Dalton, Willie Meyer, Quinton Davids, Jannes Labuschagne, Corne Krige, Bobbie Skinstad (capt), Andre Venter
