The 23-year-old striker has put pen to paper on his improved contract, committing himself to Leeds until the summer of 2010.
The revised terms are a just reward for his form so far this season which saw Beckford score six times during the first two months of the League One season.
United are also on the verge of agreeing new deals with Jonathan Howson until 2010 and Robert Bayly, Scott Gardner and Ben Parker are all poised to extend their contracts until 2009.
Leeds have also been in contract negotiations with Tresor Kandol and both parties are understood to be on the verge of an agreement.
