Daniel Qualter has been named alongside Michael Kearney in the second row with Aaron Connelly making his tournament debut in the back row.
Iain Henderson, Dominic Gallagher, and Luke Marshall have been named in the replacements.
Speaking about his selection, Ruddock said "We have looked closely at South Africa and they present another massive challenge. Typically they are a big and very physical side. Combine that with a four day turnaround and it is important that we introduce some freshness into our team. As such I have made five changes to the team that played England. The players coming in are all experienced age grade internationals and they will be keen to perform on the big stage."
Ireland Under 20s play South Africa Under 20s in Treviso this evening at 8.10pm (7.10pm Irish time), the game will be televised on Sky Sports 3.
