Hobbywing 30820202 - 23T 5mm 48P Steel Pinion Gear for RC Cars - High Durability Pinion  [HW-30820202]

Heavy Duty Pinion by Hobbywing for 1/10 Scale

The Hobbywing 30820202 - 23T 5mm 48P Steel Pinion Gear for RC Cars provides a sturdy option for rigs that see hard running. Manufactured from 40CR steel and hardened to 48-53HRC, the pinion resists wear while keeping tooth profiles true. Its 5mm bore fits common motor shafts found in 1/10 SCTs, trucks, and monster trucks.

Simple Ratio Changes for Different Tracks

Use the 23T as a baseline and swap to other tooth counts to change acceleration and top speed depending on the surface. A smaller pinion improves crawl and low speed control, while a larger pinion favours higher top speed on flatter courses. This lets builders tune their drivetrain without major mods.
