Traxxas 4-Tec 2.0 Spec


The 4-Tec Spec is a beginner to intermediate class designed to provide fun, close racing while keeping costs down to encourage participation. It is NOT meant to be a fast class that competes with our other Intermediate to Advanced classes. These kits are ready-to-race out of the box (just add batteries) and are fun for racers of all skill levels and ages.

Frequently Asked Questions

Should I leave the brake shoes on?
If you are using the optional hexes and USGT tires you will need to remove the brake shoes or they will rub on the wheel. If you are using the stock hexes and wheels you can either leave them on or take them off according to your preference.
