These helixes incorporate a multi-angled design to transfer the most horsepower to the ground while still providing great backshift. The initial angle is aggressive to get your sled out of the hole or up on the snow quickly. The finish angle ensures optimum backshift for running in a variety of elevations and snow conditions. 

Compatible with electronic reverse and non-reverse models.
