This innovative riser system works on all brands of snowmobiles with a flat steering post! The Universal Pivoting Riser raises your bars 3 and can be used alone or extension blocks can be added for up to 6 in total height. Dual pivot points allow your bars to be positioned front to back, and rotated up or down for optimum positioning.
