Have a need for pinewood derby performance? Try our Pro Stainless Steel Axles! These axles are precision, CNC-machined for top performance. They are equipped with a two-step, straight, round, and smooth shaft, and a slightly tapered head to reduce wheel-to-axle contact.

The two step shaft provides a good fit with BSA, PineCar, Awana, and MV wheels, while simplifying installation into the block. In addition no preparation is required as there are NO BURRS OR CRIMP MARKS, and the axles have a smooth hard finish.


  • Burrs and crimp marks are not present, eliminating tedious work.
  • The axle head is slightly beveled to minimize contact with the outside wheel hub, and accurately replicates the head of a BSA nail.
  • The axle shaft is formed to a high tolerance, ensuring top performance.
  • The two-step axle shaft includes an oversized section to minimize wheel wobble, and a standard diameter section for easy block mounting.
  • The superior stainless steel provides a smooth hard surface. No preparation is required.(1)
  • The Viper axles have two grooves on the axle shaft to minimize contact with the wheel bore.


Pro Stainless Steel Axles substitute for official BSA, PineCar, and other nail type axles.(2) However, while these axles closely resemble BSA axles, they are not the official nail, and are not exact replicas.
