ARRMA 13T 0.5 Mod CNC Pinion Gear With 2.3mm Bore For RC Cars Beefy High Strength Steel Precision Cut Teeth For Smooth Operation And Hardcore RC Racing Ready Performance In Extreme Conditions
✔️ 13T pinion, 0.5 mod, 2.3mm bore, CNC machined, hardened steel
This 13-tooth CNC pinion gear is a single-piece, high-strength steel gear designed for RC cars that use a 2.3mm motor shaft bore. It's a direct replacement for models that require a 2.3mm bore, delivering precise mesh and smoother operation under demanding race conditions.
✅ Strong steel construction for durability in extreme RC conditions
✅ CNC machined teeth for precise engagement and smooth operation
✅ 0.5 modulus for balanced mesh and torque capacity
✅ 2.3mm bore fits motor shafts and standard spurs
✅ Includes a set screw hole for secure mounting
💡 What is a pinion gear used for in RC cars and why is a 13T 0.5 mod with a 2.3mm bore a good match? This handy overview explains how pinions influence acceleration, torque, and top speed in common RC racing setups. - Pinion size defines gearing ratio and acceleration profile - 0.5 modulus gives stiffness for reliable mesh under high RPM - 2.3mm bore ensures compatibility with motor shafts
