Wigan have tied brothers Joel and Sam Tomkins to new five-year contracts, as well as agreeing new deals with four other first-team regulars.
Sam Tomkins, 21, had four years left on his deal, but second row Joel, 23, was due to be out of contract this year.
Loose forward Liam Farrell, 21, and young centre Josh Charnley, 19, have also signed new five-year contracts.
England winger Darrell Goulding, 22, and second rower Harrison Hansen, 25, have penned three-year deals.
The double deal for the Tomkins, which commits them to the reigning Super League champions until 2015, effectively ends any realistic chance of either player moving to Australia or switching codes to rugby union.
"It is excellent news for the club and its fans that we have been able to secure the long-term future of both Sam and Joel," said Wigan chairman Ian Lenagan.
"The pair played a huge part in what Wigan achieved last season and are a major part of our plans for the next five years.

"Whilst rumours suggested the inevitability that such players must move to NRL clubs or rugby union, we are delighted at their preference for rugby league, their loyalty to Wigan and their belief that in Super League they can be part of an evolving and winning England team."
As for the other four Warriors to sign new deals, Manchester-bred Kiwi Hansen's new contract will take him to 10 years with the club.
"Darrell, Harrison and Liam all played an important role in our team success last season," said Wigan coach Michael Maguire.
"As we all know, Josh went on loan to Hull KR and performed outstandingly well. During pre-season, all of the players have showed the hunger and desire that is required to reach the very top."
Added to that, Maguire, who will start the new season without points machine Pat Richards and new signing Brett Finch, has promoted six youngsters to his Super League squad.
And they include 18-year-old hooker Logan Tomkins, younger brother of Joel and Sam, who played alongside them in Wednesday's trial match at Warrington.
