HRNSG22M1 - 22t Steel Mod 1 Pinion Gear 5mm

This product is a hardened steel pinion gear designed for use in Mod 1 drivetrain systems where durability and precision matter. The CNC machined steel construction increases resistance to wear and stripping under high torque or high speed conditions compared to softer materials. The 22 tooth Mod 1 profile provides a specific gearing ratio when paired with corresponding Mod 1 spur gears, allowing fine tuning of acceleration and top speed characteristics. A 5 mm bore size fits common pinion shafts used in larger RC vehicles and speed‑run platforms. Precision cut teeth and hardened finish help maintain smooth mesh and consistent power transfer during demanding use.

• Hardened steel construction for improved strength and wear resistance
• 22 tooth Mod 1 gear profile for compatibility with Mod 1 spur gears
• 5 mm bore size fits standard pinion shafts in many large scale RC drivetrains
• Precision machined teeth help maintain smooth gear mesh
• Suitable for high‑power brushless and nitro setups demanding strong pinion gears
• Helps fine tune acceleration and top‑end speed when paired with appropriate spur gear
• Direct replacement upgrade over stock pinion gears
