England's 25-10 win in the final match of their three-Test series was enough to see them jump two spots to No 4 in the rankings.
Australia, who lost 20-16 to Ireland in Sydney, also moved down a spot to fifth, while the Irish in turn closed the gap to leaders New Zealand, despite the All Blacks' dominant 49-14 win over France in Dunedin.
Argentina, woeful in losing 44-15 to Scotland, cling to their 10th spot, marginally ahead of minnows Japan.
With Tests now over for the June window, the next matches to affect the rankings will take place during the Rugby Championship starting on Saturday, August 18.
