Northampton have agreed new contracts with five of their first-team forwards covering the "foreseeable future".
Flankers Tom Wood and Ben Nutley, lock Christian Day, hooker Mike Haywood and number eight Sam Dickinson have all agreed to new terms.
Saints coach Jim Mallinder said the deals "reflected the strong position the club finds itself in".
"It is a big statement for the club and the players that these agreements have been done so early," he said.
"Our aim is to have as good a squad as we possibly can, and this starts with making sure we re-sign the quality players we have here already."
Flanker Wood joined Northampton from Worcester in January 2010.
The 27-year-old has since made more than 70 appearances in a Saints shirt, been awarded the Premiership Player of the Season in 2010/11 and captained England on this summer's unbeaten tour of Argentina.
A new contract for 28-year-old Dickinson shows how highly the club rate the former Rotherham Titans player, after his first season with Northampton was ruined by injury.
Dickinson broke his arm just days after signing for Saints in March 2012 and he finally made his debut on 7 September this year in a win against Exeter.
Former England Under-21 captain Day, 30, began his career at Sale Sharks before arriving at Franklin's Gardens in 2008.
Haywood, 22, and Nutley, 21, both came through the club's academy system and between them share over 90 first-team appearances.
