A stabilizer made of metal or plastic, fit on snow vehicle ski. It comprises a vertical fin forming a wing of a U-shaped section of a length sufficient to cover the bearing surface of the ski. A central channel is placed longitudinally in the centre of the U-shaped section to form with the wings a series of three parallel guides, digging a track on a surface to stabilize the direction of the ski in motion. When applied to a snowmobile ski the central channel is a bar such as used currently to protect the ski in asphalt crossings. Its wings are of steel and have a wall 19 mm high and 2 to 3 mm thick. The web is 56 to 58 mm wide and supports a corrector 6 mm thick and 56 mm wide and stretches on all the ski length. The bar is 6 mm higher than the wings.
