This steel spur gear is a hardened replacement designed for 1/10 scale Traxxas 4-Tec 2.0 and 4-Tec 3 vehicles that use a 48P drivetrain. Machined from hardened steel with a black oxide finish, it provides elevated strength and wear resistance compared to standard nylon gears while maintaining a precise tooth profile for smooth power transfer. The 70-tooth design helps balance torque and acceleration while fitting directly into the drivetrain with no machining required. Its lightweight but robust construction contributes to consistent performance under high-load conditions. Ideal for racers and hobbyists looking to improve drivetrain durability and reliability.
Hardened steel construction for superior strength over stock nylon gears
70 teeth at 48 pitch for optimized drivetrain ratio in 4-Tec platforms
Black oxide coating enhances corrosion resistance and reduces surface wear
Direct replacement for the factory spur gear without modification
CNC machined and lightened to reduce unnecessary mass
Designed to pair with a hardened 48P pinion gear for proper mesh
Improves drivetrain durability for aggressive driving and racing
