Derbyworx Pinewood Derby 4 Groove Racing Axles DWX4GA01 np TWIN METAL GUN BARRELSThis axle starts life as an official B. S. A. Pinewood Derby axle. It is C. N. C. machined true and round, we then add 4 grooves (1 behind the axle head and 3 in the hub contact area) to reduce friction and hold graphite then head is back cut for further friction reduction at the hub face on the wheel. They are semi polished so the builder can finish it their spec. The Pro 4 Grooved Axle is our preferred choice when using a Racing Graphite Lubricant.
