4-Pack Steel Pinion Gears for 1/8 RC Cars, 5mm Shaft ✔️ 28T-31T steel pinions with 5mm shaft, M4 screws included

These steel pinion gears are built for 1/8 scale RC cars and work with both brushed and brushless motors that use a 5mm shaft. The set is designed to endure high-torque runs, providing long life and strong wear resistance in demanding racing or bashing scenarios.

✅ Four-piece steel pinion gear set (28T, 29T, 30T, 31T) for tuned performance on 1/8-scale RC cars with 5mm shafts
✅ Wide, thick gear teeth and deep grooves to handle high loads without tooth stripping
✅ Includes M4 set screws (12.9 grade) for secure mounting on motor shafts
✅ Compatible with 1/8 scale RC car brushed and brushless motors with 5mm shafts
✅ Hardened steel construction for durability and long life under tough RC use

💡 What is a pinion gear used for in RC cars and how does it affect performance? Pinion gears set the motor-to-drive ratio and influence torque and speed. - Higher tooth counts boost top speed when paired with a matching spur gear - Lower tooth counts increase acceleration and wheel torque - Steel pinions resist wear during hard runs, improving durability
