Robust AX-30390 gears for demanding EXO use

The Axial AX-30390 Differential Gear Set fits the EXO platform and uses powder metal for a balance of strength and wear resistance. These gears are intended to give consistent torque distribution and stand up to the knocks of hard-packed tracks and uneven trails.

Performance and build notes

Material: Durable powder metal delivers longer service life in abrasive conditions.
Compatibility: Designed specifically for the Axial EXO chassis geometry.
Performance: Improves drivetrain efficiency and steadies handling under load.
Application: Ideal for circuit racing, bashing and varied off-road environments.

How do I check gear mesh after fitting?

Fit the gears then rotate the drivetrain while checking for smooth contact and minimal play. Adjust pinion height or shims until the mesh is even across the teeth.

Are these suitable for high-power motors?

They increase durability over stock plastic parts, but for extreme power builds consider hardened steel upgrades depending on power and running style.

What inspection routine should I follow?

After heavy sessions inspect for tooth wear, chips and bearing play. Replace gears showing significant damage to avoid secondary drivetrain issues.

Will installation change gear ratios?

This is a like-for-like replacement so gear ratios remain unchanged, but mesh and pinion selection can affect final drive feel.
