Woody's Trigger Lake Racing Studs are built for lake ice, with a short, narrow, tapered profile that penetrates hard ice for traction. The through-hardened carbon steel body and 60-degree carbide insert are designed for two-ply tracks and support plates, while the 15/16-inch head with anti-rotation lines keeps each stud locked in place. This 48-count set includes the proper nuts, so you have everything needed for a full installation.
