Can I use these gears with aftermarket diffs?

You can often pair these components with compatible aftermarket diffs, but check tooth counts and shaft interfaces to confirm fitment.

Do these parts need bedding in?

A short bedding-in period at low speed helps seat gears; then recheck mesh and fasteners before full-power running.

Will this reduce drivetrain noise?

Properly installed with correct mesh and lubricated bearings, the UB033 can reduce play and lower noise compared with worn components.

Is special lubricant required?

Use a light gear grease recommended for RC drivetrains; avoid heavy pastes that can bind small gears.
