Only similar part number that I could find was the Wagner severe duty brake pad set from Advance Auto Parts: part number SX804...
Wagner lists their pads as part number MX804 for the front and QC627 for the rear. And the rest of the manufacturer's I found had part numbers ending with "804" for the fronts and "627" for the rears. So it seems like your front are OK, but I'd check the rears.
