An effective aftermarket option to firm up front differential durability and reduce gear wear without modifying axle geometry.

Is this a full replacement for the front ring and pinion?

Yes, the set replaces the original ring and pinion inside the front gearbox and includes screws for installation.

Do I need special tools to fit these gears?

Standard small hex drivers and feeler checks for gear mesh are usually sufficient; no specialised tooling is required beyond common RC hand tools.

Will these change gear ratios?

No, the set replaces the existing ring and pinion with the same tooth counts to maintain stock ratio while offering improved material strength.

Any lubrication recommendations?

Use a quality gear grease suited for metal gears and ensure bearings are clean before reassembly to achieve best life and smooth operation.

Are these suitable for repeated impact use?

Hardened steel gives improved resilience versus softer gears, but extreme impacts can still cause damage; ensure proper setup and consider other drivetrain reinforcements for heavy impact use.
