A precision aftermarket option to increase front differential durability and maintain accurate gear mesh in demanding RC applications.

What are the expected benefits of hardened steel #45 in this application?

Hardened steel #45 offers improved surface hardness and wear resistance, helping the gear tooth form remain stable under continuous load and reducing the rate of pitting and profile degradation.

Are any setup adjustments recommended after fitting?

Verify backlash and tooth contact pattern, use a thin smear of appropriate gear grease, and torque fasteners to manufacturer guidance to avoid introducing preload or binding.

Is this kit compatible with aftermarket bearing or shim upgrades?

Yes, the kit is compatible with common bearing and shim upgrades for the front gearbox, but confirm dimensions before installation to ensure correct mesh and axial play.
