Most events use detailed min/max specs that must be heeded to avoid the dreaded DQ. Having access to precise measuring tools is essential.
Any racer will tell you that weight is the enemy of speed. Encourage students to think about this during all phases of the project.
Minimizing rolling resistance is a game changer. Wheels should spin freely, and the guide should never drag on the car body as it moves down the track.
The science of aerodynamics applies to CO2 dragsters. Wind tunnels enable students to visualize the effectiveness of their design.
Jazz up your cars with our chrome axles. Steel axles are nickel coated to create a finished look for race cars – plus the slick surface decreases the amount of friction produced. 1/8" x 70 mm.
Use this self-lubricating material for axles. Lighter weight and less friction mean faster speeds. Comes in two-foot lengths. Cut axles to desired lengths using the Precision Metal Saw.
Cut your dragster’s axle weight in half by using aluminum instead of steel! Buy these 1/8" diameter axles precut, or cut your own from our three-foot lengths. Use the Precision Metal Saw to cut axles to desired lengths.
These lightweight spacers can be placed between the wheels of shell cars and can also function as friction-reducing axle bushings. 1/4" outside diameter x 1" length.
These low-profile rings are placed on the outside of shell car bodies to hold the axle in position. 1/8" inside diameter.
This solid brass axle material is an alternative to steel for CO2 dragsters, mousetrap vehicles, and other model vehicles. When used with brass bushings, this material has ultra-low friction to help you increase speed.
Rods are 12" long – cut them to length using a metal saw, sold separately.

Washers reduce friction between the wheel and the dragster body. 1/8" inside diameter.
