Overview
Maximize top-end speed on your Traxxas 4-Tec 2.0 with the Hot Racing 48T 48-Pitch Speed Run Hardened Steel Spur Gear. CNC-machined and lightened from hardened steel and finished with a black oxide coating, this purpose-built 48-tooth, 48-pitch spur is engineered for drag racers, speed-run drivers, and high-power on-road builds chasing maximum mph.
The aggressive 48-tooth count is the lowest in the Hot Racing 4-Tec 2.0 spur lineup, delivering the fastest possible final drive ratio. Hardened steel construction stands up to the brutal torque loads of high-power brushless systems where stock nylon spurs strip in seconds.
