A New Blizzard Wing B53062-1. This is the early version. This wing fits all the 860SW and only the older 8600SW. This was a 8'6" Speedwing plow. This is just for the driver side. It comes just as you see - no cutting edge.
If you need the passenger side, that would be part # B53075-1.
If you have the newer version of the 8600SW, then this wing is part # 42385. The SnowEx Grey version is 84652.
