Pine-Pro axles are used for Pinewood Derby cars. Will not work with Pine-Pro wheels. Intended for use with solid axle styles such as Pinecar.
Length: 2-1/2" (64mm)
Typically with any pinewood car you have four axles that will need worked and made true. When I saw this, I thought it can't be legal, but it is and thus far, only RC Planet has them. Huge time saver and great selection.
