Low Profile Pinewood Derby Block with Axle SlotsThis low profile wood block is slightly over ¼″ thick. The body is cut from the Official BSA Pinewood Derby Block. This thin body creates an extremely aerodynamic car and it allows you to place the majority of the car's weight exactly where you need it in order to optimize the placement of the center of gravity. This means more speed. This block includes the BSA axle slots at the standard BSA Pinewood Derby wheel base. These blocks meet all BSA Pinewood Derby dimensional requirements. The dimensions are 7″ long x 1¾″ wide x ¼″ thick.If you need axle holes check out the Incinerator Body.
