This hard steel gear set is made for differential assemblies on TRAXXAS 1/10 Slash 4x4 and other listed 1/10 TRAXXAS 4WD models. The kit contains 4 steel replacement gears that substitute softer metal or plastic originals to increase wear resistance in high-torque brushless setups. The design preserves original tooth profiles and mesh geometry rather than changing gear ratios or clearance settings.
Installation notes: inspect bearings and housings for wear before installing, remove debris from mating surfaces, and apply a light gear lubricant during initial break-in. Set backlash and tooth mesh under load, then re-check and tighten retaining hardware after the first few runs. This part is intended only for RC differential assemblies and not for full-size vehicles.
Use these 4 steel gears as drop-in replacements for worn differential internals on supported TRAXXAS 1/10 4WD platforms; pair with light lubrication and routine inspection to extend service life.
