This six piece set provides carbon steel spur and pinion components engineered for rear gearbox service on compatible TRAXXAS 1/10 2WD platforms. The primary gears are a 56 tooth spur and a 15 tooth pinion, with the pinion noted to correspond to TRX4015T for shaft compatibility checks.
Designed as service items, these gears permit ratio changes and worn gear replacement. Correct assembly requires verifying pinion depth, even tooth contact across the spur, and secure installation of the included 3x3 screw shaft and three 3x7x0.2 stainless washers to maintain alignment under load.
