Thanks to the aggressive and semi-aggressive Snowtracker kit, you will find the pleasure of driving your snowmobile on straight or curved trails, with an aggressive grip and without swaying. By installing a Snowtracker, you will now have absolute control, unmatched traction and optimal precision with your snowmobile.Including self-sharpening healds with 6 to 7.5" of carbide (depending on the ski model of your machine). The healds and stabilizers offer a penetration of more than 1" deep in the snow. The height of the stabilizers is lower than the beams, so the stabilizers will not touch the paved path. It is only the carbide of the arm that will wear. The sharpening of self-sharpening heddles occurs when the steel of the heald wears on each side of the carbidelames forming the same principle as sharpening a lead pencil. Here is that the carbide being harder than the sides of the arm, the steel of the arm wears out a little faster in the gravel and on the asphalt it is the carbide which rubs the most therefore what produces a balanced sharpening during throughout the wear of the carbide. Also the wear of the arm being slowed down by a heat treatment to be more resistant to wear. Therefore, the arm always keeps its cut in new condition during the complete wear of the carbide, for more performance and grip on ice and snowmobile trails.NOTE: For aftermarket Curve XS skis.
