Tundra Flex Weight cylinders are a new composite weight for Pine Derby® cars with the density of steel but are made with a child-safe, non-toxic material.

Package includes two 25/64" diameter by 5" long cylinders that can be easily cut with a scissors, drilled, shaped, sanded and painted so you have maximum flexibility.

Drill a 7/16" hole in the back of your pinewood derby car, insert the amount of weight you need and cut off excess weight with a scissors.

Weights are hidden inside the car body for a clean look, or you can shape them and glue anywhere...make a canon, exhaust pipe or turbo jet!

Note: Flex Weights are made from a composite material so there could be slight variations in diameter.

Flex Weights are a low cost, non-toxic alternative to zinc, lead and tungsten.
