ARMORskids Pro Series Heavy Duty Snow Blower Skid Shoes. Fits 2.5", 3.75", and 5" bolt spacing. Replace the cheap plastic skids that come with most snowblowers and wear out in no time. These are made of solid steel with a half inch thick bottom plate that will outlast your snowblower! The slots give 2.25" of vertical adjustment. Overall height is 3.5", length is 12.375", and 1" wide. They are also reversible, with one end narrow to cut through the snow. Great for smooth paved surfaces. Mount with the other wider end forward to glide smoothly on gravel or rough surfaces without excessive digging in. Listed online on snowblowerskids.com at just over $100USD with shipping plus tax. Easily worth over $150CAD but well worth it. I bought two sets years ago. Only ever ended up using one set that were still in great shape when I sold the snowblower. They don't fit my new one.
