Ford's deal comes as Loko Jnr Pasifiki Tonga officially closes a chapter on his demands for an early release by re-signing with St George Illawarra.
Currently sidelined with a pectoral injury, Ford led the Dally M Medal count earlier in the season and has become prized for his heavy work rate through the middle.
The Warriors prop narrowly missed out on a State of Origin debut for NSW this year and was averaging a career-best 161 metres per game before going down in June.
He is expected to return for the third-placed Warriors' finals tilt and will remain at the Auckland club through 2029.
"You're not meant to have favourites, but he's one of my favourites," said Warriors coach Andrew Webster.
"There's not many front-rowers that play the way Jackson does, that can do what he does. If the game went for two days, Jackson would still be playing for two days.
"I'm really proud of him, I'm really happy for his whole family that they're going to be here in New Zealand for a little longer."
Pasifiki Tonga has signed his own three-year contract extension, only months after agitating to leave the Dragons, where he made his NRL debut last year.
By April, the 21-year-old was growing frustrated his limited playing time under coach Shane Flanagan.
But since Flanagan's exit the prop has gone on to become a mainstay of the youthful pack deployed by Dean Young.
Pasifiki Tonga has played 13 games this season and been elevated to a starting front-row berth under Young.
"I'm really excited to be extending my time here at the Dragons under Dean Young," Pasifiki Tonga said.
"I've been enjoying my footy and I believe in the direction that Youngy is taking us.
"I've been at the Dragons since I was 17 years old; I've grown up here and I've built a lot of relationships. I love my teammates and I'm confident that we are on the way up here."
Pasifiki Tonga joins Hamish Stewart, the Couchman brothers, Ryan and Toby, and Dylan Egan in committing to the Dragons on long-term deals, creating hope that a core of young forwards can help turn the club around and end their finals drought.
Meanwhile, Newcastle have cemented a new deal for Francis Manuleleua.Â
The 22-year-old Knights back-rower, who made his NRL debut in round three, has penned an extension until the end of 2028.
