ESPN reported the deal is worth $50 million over five years, with $25 million guaranteed.
"I like the defense we are on now, I like the group of guys we have in the locker room," Kendricks said at a news conference announcing the deal. "I'm just excited to get another opportunity to play with them. A crazy front in front of me, so that's another factor that came into it. At the end of the day, I just want to be out there playing football and winning championships."
Kendricks is scheduled to make a base salary of $1.138 million in 2018 in the final season of his four-year rookie contract.
Kendricks has recorded 314 tackles over his first three NFL seasons, including a career-best 113 in 2017. He also has 7.5 sacks and two interceptions -- returning both for touchdowns.
Kendricks, 26, was a second-round pick (45th overall) in 2015 from UCLA. He broke into the lineup in Week 4 and has since been a mainstay as the team's top run stuffer.
"That was a huge moment for my family," Eric Kendricks said. "Obviously, it didn't end well for us. It ended very good for my brother, and he was able to go on and win in the Super Bowl. Going back home and talking to him and that's one of the things that we dreamed of growing up playing this sport, so it's been cool.
"I can't say it makes me any hungrier. I've been hungry. I just know what I want and I kind of just work to get it, period."
