This High Strength Gear Kit provides several new gears with features to handle higher loads. Each of these gears has a wider face width; this means each tooth is wider so applied loads will be spread over a larger area.
 
The 12-tooth High Strength Gear is molded out of powdered metal. The 36-tooth and 60-tooth Gears have powdered metal inserts. These metallic components will protect the gear from high loads applied by a VEX axle.
 
  
High strength gears mate with all VEX spur gears.
  
Double-thick face width provides added tooth strength.
  
Metal Square Hole Inserts prevent axles from "stripping".
  
Use metal pinions for high strength where it counts.
  
Use the round-hole inserts to build free spinning idler gears.
  
Build gearboxes that resist high shock-loads.
  
Bolt Gears together for added strength.
