Axle keyway for Invader racing go karts. These axle keyways are designed to support kart hubs, brake carriers, sprocket carriers, and components for 40 or 50mm axles with pre-drilled peg holes, and are designed to fit a '3-peg' design.
Each keyway is 8mm in width, with (3) 7.5mm diameter pegs, spaced at 15.0mm from each other, center-center. This spacing is critical to ensure correct fit, as not all keyways are created in this same dimension. The height of the keyway is 3.50mm.
