With the introduction last year of the very open running boards on Summit Liquid-cooled models that were designed to reduce snow and ice build-up in deep powder, some very aggressive or heavier riders found the running boards could possibly sag or bend while riding in extremely rough conditions.
Ski-Doo now offers a running board reinforcement kit to strengthen this area of the running board, as well as triangulate the foot well area for improved strength. Order part #861 804 300. This kit contains all necessary reinforcing parts, including rivets and instructions. The kit will add a slight amount of weight, but the running board will be considerably more rigid.
