We engineered our PRO pinewood derby axles from scratch to fix the imperfections of a standard kit axle, like burrs and crimp marks, and built our speed secrets right in. Each one is machined and nickel-plated, with friction-reducing grooves and wobble-eliminator grooves that help your wheels spin smoother and straighter. They're built for speed in races that allow them, so check your race rules first.
