## Description

Get strong dense flexible weight for your pinewood derby car with the Gravity Assist Kit! Included are 8 tungsten cylinder weights and 10 small tungsten balls. Use the cylinders to get you up to weight quickly. And then use our tiny tungsten balls to get to the maximum allowed weight with precision.   Tungsten carbide is a alloy made up of over 95% tungsten and is denser than either zinc or lead. So you get more weight in less space! To use, just drill a hole with a standard 3/8 inch diameter drill. The cylinder weights slip right in. Then add some of the small tungsten balls to get you to the exact weight allowed. After the all the weights are placed, close the hole with wood putty and sand and paint. Get maximum aerodynamics and a professional look! 8 - 0.3 oz 3/8 diameter cylinders 10 - 0.028 oz 0.177 diameter spheres

## Features

- Go fast - Cylinders allow precise placement in the car and the balls give you precise weight control.
- Look good - Weights can be hidden in the car by drilling a 3/8 dia. hole and filling with wood putty.
