The EC #40 Pitch Aluminum Sprockets were initially designed for racing lawnmower applications.Â
The increased power demanded a strong sprocket and drive train over the traditional karting #35 sprocket and drive train. They are made with the standard six-bolt 5.25″ bolt circle and 4.5625 bore to fit the common sprocket carrier. We highly recommend using a heavy-duty sprocket carrier like our 3602. These sprockets are manufactured with 0.25″ high-quality aluminum, hard-anodized bright red for added durability, and a great look.
NOTE: 46t, 48t, 50t are currently non-anodized silver, not red.
