3 Pack Hardened Steel Pinion Gear Set 0.6 Mod 3.175mm Bore For 540 550 RC Motors, 26T 27T 28T Pinions, Brushed Or Brushless, Fits 1 Tenth Scale RC Cars
✔️ 3-piece hardened steel, 0.6Mod pinions: 26T 27T 28T, 3.175mm bore
This 3-pack pinion gear set is crafted from hardened steel for RC cars using 0.6 Mod gears. With a 3.175mm bore, these gears fit most 540/550 brushed or brushless motors and pair with compatible 0.6M spur gears in 1/10 scale electric builds. Each gear is CNC machined for precise meshing and quieter operation. The kit includes 3 pinions, screws, and a small hex wrench for quick installation.

💡 What is a pinion gear set used for in RC cars, and why is a hardened steel version handy?
A pinion gear set translates motor RPM into drivetrain speed, letting you tune for more speed or torque. Hardened steel is handy because it resists wear and maintains accurate meshing during high-speed runs.
- Higher wear resistance under heavy use- Maintains precise meshing during high RPM
- Lets you tune speed/torque with different tooth counts
- Includes installation hardware
