Here is a New Aftermarket Blizzard Slide box wing cylinder. From Blizzard this same Cylinder is $305. They had more than 1 slide box cylinder. This is the one with 2 hoses fits 810, 8100, 8100PP, 810SS, 810PP, and 810TR. This goes in the plow to slide the power wings in and out. It is a Dual acting cylinder so power in power out. This is considered a 1-1/2x13-15/16. The Blizzard part # is B60347 or 60347 The aftermarket # is 1304646. If they are pitted they should be replaced those pits take in water and will cause freeze up in the pump. But if youa re looking for this you probibly hit something and its bent. Just a guess. Also get some Blizzard fluid while you are at it.
