This is the Axial Heavy Duty "Underdrive" gear set for the AR60 axle. Installing this overdrive set in the rear axle will allow it to pull slightly less than the front axle, helping torque twist. By running this, you essentially run an overdrive front gear set, helping cornering. We do not recommend using the underdrive gear set for the front axle.

• Spiral cut gears offer increased gear tooth contact and run quieter
• New gear ratios offer a low gear and high gear range
