Brothers Michael and Joel Monaghan are among 11 Warrington Wolves players to sign new contracts.
Hooker Michael, 33, whose contract was set to expire at the end of the season, has been given a new 12-month deal while winger Joel, 31, has signed an extension taking him to the end of 2017.
The Wolves have handed new two-year deals to prop Paul Wood, 31, hooker Micky Higham, 32, and winger Chris Riley, 25, who were all out of contract in November.
Centre Ryan Atkins, 27, centre or second rower Simon Grix, 27, and back rower Ben Harrison, 25, have extended their contracts until the end of 2017 while Warrington have also handed new deals to fringe players Glenn Riley, Ryan Shaw and Danny Bridge, who have spent most of the season with Championship partners Swinton.
The announcements confirm coach Tony Smith's desire for continuity. The Wolves were the only Super League club not to make a signing ahead of the 2013 season.
"We are delighted to be retaining the stability of our squad and we are really pleased that these players are staying on to help continue to build this great club," Smith said.
"The fact that we are getting stronger as a squad each year has probably been shown by the number of consecutive wins we've had recently.
"It has shown that we are still improving and we are striving to get better and better each year.
"We've got some terrific young players coming through and the consistency of our senior players has been fantastic as well.
"We are delighted that we will only have a small turnover of players once again - that's the way we like it at Warrington."
Warrington are parting company with veteran props Garreth Carvell and Adrian Morley, who are joining Bradford Bulls and Salford City Reds respectively, and have confirmed the signing of South Sydney's former New Zealand Test front rower Roy Asotasi.
