Wing Tom Brady, front-row forward Aston Croall, lock Tom Holmes and number eight Mark Easter have all agreed fresh terms with the Premiership club.
"All four are really good lads who have a great work ethic and they are people who care about the club," Sale rugby director Steve Diamond said.
"We are really pleased that they have all re-committed to Sale, and they will be very important to us going forward into next season."
