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

The IF410-46C from Kyosho serves as a straightforward replacement spur for INFERNO MP9 and MP10 cars, produced with a 46-tooth profile. It returns correct gear engagement and supports intended drivetrain geometry for these buggies.

Use the IF410-46C where the stock layout specifies a 46-tooth spur on INFERNO MP9/MP10 platforms. During replacement, confirm pinion alignment, centre diff clearance and bearing condition to maintain smooth gear operation and even wear.

In tuning, a 46T spur keeps the factory ratio when combined with different pinion sizes, giving predictable effects on acceleration and top speed without modifying gearbox spacing or chassis mount points. Fit shims as required and check backlash against the manufacturer's guidance.

Fitting advice: clean mating surfaces of any flashing, secure the motor pinion, and inspect surrounding bearings and gearbox seals while the spur is accessible. Regular checks help prevent accelerated wear and reduce drivetrain inefficiency.
