Narrow pivot riser blocks are designed to be replacements for risers found on Arctic Cat, Polaris and Yamaha snowmobiles. If your sled has a 3.125" wide riser and a "T" post you can easily raise your bars by replacing the stock pivot riser with a longer PowerMadd pivot riser. The Pivot riser is tapped with metric threads so that is works with your stock handlebar clamps and existing bolts.
