Build mechanisms capable of achieving higher torque or speed than ever before - lift heavier loads and survive bigger impacts with the additional gear ratio options provided by the largest high strength gear available.
- Works with the VEX High Strength Gear Kit or any VEX spur gear
- Double-thick face width and ribbing provide added strength
- Metal Square Hole Inserts prevent axles from "stripping"
- Build gearboxes that resist high shock-loads
- Bolt gears together for added strength
