The bottom lead cylinders weigh .7 oz and are 1 5/8" long!

Tungsten gives you four advantages:

  1. You can pack more weight in a smaller area giving you more flexibility in your car design.

  2. You can place weight exactly where you need it for maximum speed.

  3. Tungsten has the added advantage of being non-toxic, so you do not need gloves to handle it.

  4. Diameter is 3/8". Just drill a 3/8" hole and slide them in. Use wood putty or glue
    to seal the hole.

      Tips & Hints

      When your car wheel rubs against the axle head it can cause the wheel to wobble because the corner of the axle head is not a perfect 90 degrees. Cutting a groove directly under the axle head removes this source of wheel wobble. Cutting this groove is difficult to do by hand, but it can be done with an axle file. Our grooved Speed Axles and Pro Super Speed axles have this groove, exclusive to Pinewood Pro, cut directly under the axle head.

      Nyoil stays on your axles throughout the race, unlike powdered graphite that blows off every time your car goes down the track. This gives Nyoil coated axles a speed advantage if your car keeps racing.

      Wood filler is your best friend when it comes to building a pinewood derby car. Use wood filler to fill holes, gouges and other cutting mistakes. You can even use it to add a bubble, racer cockpit, spoiler, etc.
