Shop our selection of 1:32 slot car pinion gears for building, repairing, and tuning slot car drivetrains. Pinion gears mount to the motor shaft and transfer power to the axle gear, making them an essential component in inline, sidewinder, and anglewinder drivetrain configurations.

Choose from a variety of tooth counts, gear pitches, and sizes for replacement, performance upgrades, and race tuning. Changing the pinion gear can alter the overall gear ratio, allowing you to fine-tune the balance between acceleration, top speed, braking, and drivability to suit your car, motor, and track.

For smooth and reliable operation, select a pinion gear that is compatible with your motor shaft diameter, gear pitch, mating gear, and drivetrain configuration. Proper pinion selection and gear mesh help reduce friction, minimize premature gear wear, and provide consistent power delivery to the rear wheels.

Looking for the matching axle gear? Browse our 1:32 Crown Gears, 1:32 Anglewinder Gears, or 1:32 Sidewinder Gears to complete your drivetrain setup.
