The Terrors host 'Gers in February after being drawn together on Monday and Ibrox fans are not in a good mood after the Tannadice outfit pushed to keep them out of the Scottish Premier League during their fall into liquidation during the summer.
"United were one of the clubs who voted against allowing Rangers SPL entry and their chairman Stephen Thompson has repeatedly, through his actions at high-powered meetings, intimated further punishment to be administered on our club.
"The Rangers support has waited patiently for the opportunity to send a clear message to those that tried to destroy our club - starve them of their much-needed cash by boycotting this game.
"It must also be remembered the disregard this club had for Rangers supporters when it unashamedly refused to offer refunds for a game abandoned due to a waterlogged pitch in 2009.
"We ask the support to resist temptation of attending the game but rather give your hard-earned cash to a Rangers-friendly pub, bar or club.
"We also understand the desire to support the team - the fans have demonstrated this to unbelievable lengths of loyalty - but we ask that on this occasion in a one-off display of fan power we show that we have not been beaten or broken.
"Our unending support of the team in SFL matches and games against non-SPL opposition continues unabated."
