Pinion Gears for R/C Cars & Trucks

Find the right pinion gears for R/C cars and trucks to tune speed, acceleration, and overall drivetrain performance. This collection includes R/C pinion gears in a variety of tooth counts, pitches, and bore sizes for electric R/C models, including on-road cars, off-road buggies, monster trucks, crawlers, and short course trucks.

Pinion gears are essential for adjusting your vehicle’s gear ratio. A smaller pinion can improve low-end torque and reduce motor load, while a larger pinion can increase top speed when properly matched with your motor, spur gear, ESC, and battery setup. Browse this collection to find replacement and upgrade pinion gears for maintenance, repair, or performance tuning.
