INFERNO MP9/MP10 46T Spur Gear - IF410-46C by Kyosho  [KY-IF410-46C]

This Kyosho IF410-46C spur gear is a direct replacement part for the INFERNO MP9 and MP10 series, specified at a 46T tooth count. It restores correct gear mesh and helps maintain the original drivetrain geometry on RC buggies.

Compatibility targets INFERNO MP9/MP10 platforms that use a 46-tooth spur as part of their stock drivetrain layout. When fitting the spur, inspect pinion engagement, center differential clearance and bearing condition to ensure smooth running and even tooth contact.

For setup and tuning, the 46T spur preserves the stock gear ratio when used with different pinion sizes, allowing predictable changes to acceleration and top speed without altering chassis mounting or gearbox spacing. Fit the correct shims and verify backlash meets the chassis manufacturer recommendations.

Installation notes: remove any burrs from mating surfaces, ensure the motor pinion is properly secured, and check surrounding bearings and gearbox seals while the spur is accessible. Routine inspection limits premature wear and reduces drivetrain losses.
