Tom, 25, has established himself in the Tigers front row this season and gained his first England caps during the autumn internationals, while 23-year-old Ben has just passed 100 appearances for the club to go with 26 international appearances.
Tigers director of rugby Richard Cockerill said: “It is excellent news that both Tom and Ben have agreed new deals with us. They are both very important to the club.
“They have grown up in a Leicester Tigers family, their dad Nick played for the club, they know the history of this place and they have come all the way through the Academy system here before establishing themselves as key first-team players.”
Scrum-half Ben Youngs made his Tigers debut as a 17-year-old in February 2007 and has played in four Premiership Finals with the club.
Tom made his club debut as a centre in December 2006 before being converted to hooker.
“Ben and Tom both have an excellent attitude to their work,” added Cockerill.
“They are the kind of players we want to build the club around for the future and we look forward to their continued development in the Tigers squad over the years to come.”
