This Delrin main gear is an aftermarket 46-tooth replacement for Kyosho Inferno MP7.5 owners needing a spare for maintenance or setup changes. It emphasises predictable Delrin wear and steady gear mesh performance, and is supplied as 1 pcs to fit the original gearbox layout.
Fitment is a direct spur assembly swap inside the gearbox; confirm gear mesh clearance and backlash when reinstalling and turn the drivetrain by hand to verify smooth engagement before running the vehicle. Modelers use this part to keep drivetrain reliability when swapping pinions or tweaking spur placement.
