Say "Good Bye" to crimp marks and burrs!! We've done all of that work for you. We take Official BSA® axles straight out of the box. Then, each axle is turned on a lathe to remove crimp marks, burrs, and surface defects. helping your pinewood derby car speed to the finish line. Each axle has also been lightly polished. The only thing you need to do is give them a final touch up polish and they're ready to race.
