THREE first-half goals at Gayfield handed Rangers their 13th successive League One victory.
Arbroath lasted little more than a minute and a half before Jon Daly crashed home his 17th goal of the season.
And the Glasgow giants pressed their case further when Red Lichties defender Bradley Donaldson put through his own net ahead of Nicky Clark's third goal for the club just before half-time.
The victory extended the Light Blues' lead at the top of the third tier to 11 points, with a game in hand against Forfar to come next Tuesday.
Although Ally McCoist's men have now won all 13 of their league games so far this campaign, they have not exactly set the heather alight of late.
But Rangers were quick out of the blocks on the Angus coast as Daly's volley ended McCoist's seven-game wait for a half-time lead.
If Arbroath had aimed to keep it tight in the early period in the hope of frustrating the visitors, their ploy lasted just 100 seconds before Daly struck the opener.
It was the seventh match in a row in which the former Dundee United striker has netted, but he was not the only man in blue to impress.
Lewis Macleod was one of two newcomers to the side – along with Fraser Aird – after Arnold Peralta and David Templeton were benched, and the 19-year-old's shot led to the second on 26 minutes when it was deflected home by Donaldson.
Clark then wrapped up the scoring four minutes before the interval by nodding home from man-of-the-match Lee Wallace's free-kick delivery.
Rangers started the second-half in the same dominant fashion that they showed in the first period but failed to add to their tally as first Daly could only find the base of the post from Black's cross and then Nicky Law blazed over after powering through the middle.
