Overview
Eliminate stripped spur gears on your Traxxas 4-Tec 2.0 with the Hot Racing 70T 48-Pitch Hardened Steel Spur Gear. CNC-machined and lightened from hardened steel and finished with a black oxide coating, this 70-tooth, 48-pitch spur is engineered for the brutal torque loads of brushless-powered 4-Tec 2.0 drag and on-road builds — where the stock nylon spur strips under hard launches.
Hardened steel construction delivers bulletproof reliability, while the lightened design preserves drivetrain efficiency and rotational mass. A direct drop-in replacement for the factory nylon spur.
