Danny Carlton, Jim Bentley and Michael Twiss scored the goals as Morecambe recorded a fine win at Halifax.
The opener came after 11 minutes when Carlton fired home after latching onto Twiss' pass.
The lead was doubled midway through the first half when Bentley headed home Kieron Walmsley's cross, although Paul Stoneman quickly pulled one back.
Carlton then hit the woodwork before the visitors sealed the win when Twiss scored after good work by Gary Hunter.
