Bradford defender Steve Williams and midfielder Lee Bullock have signed new contracts at Valley Parade.
Williams initially penned a one-year deal with the Bantams last summer, with the option of a further year's extension.
But the League Two side were keen to keep him for a longer period and have handed Williams a three-year deal.
Bullock has signed a new two-year deal which will keep him with the West Yorkshire club until July 2012.
Bullock, who joined the club from Hartlepool in February 2007 following an initial loan spell, made 45 appearances for the Bantams last season and was a key member of their starting line-up.
Meanwhile, youngster Ryan Harrison has earned a place in the first-team squad for next season by signing a one-year contract.
Goalkeeper Chris Elliott has agreed terms on a professional deal with the club and will put pen to paper later this month.
