All-rounder Calum Haggett and bowler Ivan Thomas have signed "long-term" extensions to their contracts at Kent.
Haggett, 24, has taken 22 wickets at an average of 25.81 in eight Championship outings and scored more than 300 runs.
Fast bowler Thomas, 23, has picked up 23 wickets at 26.78 apiece in nine first-class outings in 2015.
Meanwhile, 22-year-old left-arm spinner Imran Qayyum has also extended his deal after impressing for the club's second XI this summer.
Kent have not disclosed the length of any of the new deals.
"I feel I have contributed with bat and ball, but I am still learning as a cricketer and know there is room for improvement in all aspects of my game," Haggett said.
"I feel we have made great strides as a bowling unit this year in all formats and I look forward to a long stay here."
