You are buying a brand new set of (2) Zinc Dichromate plated 5/8" diameter mounting pins for Meyer Snow Plows (replace Part# 08575). They also fit most standard Receiver Hitches. These are the proper length for Meyer Snow Plows, unlike most aftermarket pins that are 6" long, and stretch over time. We replaced the standard hairpins with Lynch Pins. We upgrade the original cheesy 1/8" hairpins (that these come with) to 3/16" Lynch Pins. The cheesy Hairpins are pictured, but not included.
