✅ CNC machined hardened steel construction for durability
✅ Black oxide coating enhances wear resistance and corrosion protection
✅ Replaces factory plastic gear to improve longevity and performance
✅ Best used with a steel pinion for proper gear mesh and protection

💡 What is a spur gear used for in RC vehicles and why upgrade to steel?

The spur gear drives the drivetrain by transferring torque from the motor to the wheels, delivering reliable power and control under load. - Transfers torque from motor to drivetrain for smooth propulsion - Steel spur gear offers higher wear resistance under high torque brushless setups - Reduces gear wear and maintenance, extending service life in rugged use - Pairs with a steel pinion for precise gear mesh and better protection of your investment
