Can I reuse my existing pinion with this spur?

You can reuse a compatible 0.4 module pinion if it matches the recommended tooth counts and fits securely on your motor shaft.

Does the spur affect handling?

The spur itself does not change suspension handling, but the chosen gear ratio influences acceleration and top speed, which affects driving style.

How do I check correct mesh after installation?

Spin the gear by hand with the motor in place and use a piece of paper to set a slight clearance; tighten once the mesh is correct and recheck under load.

Is this spur suitable for club racing upgrades?

Yes, it is a direct replacement that helps maintain predictable drivetrain performance when upgrading or refreshing worn parts.
