TRAXXAS CRANIAC Monster Truck aluminium spur gear adapter and steel 58T & 18T gears by GPM CRA155818T  [CRA155818T]

Aluminium adapter and steel spur gears for TRAXXAS

This GPM aftermarket set supplies an aluminium spur gear adapter paired with steel 58T and 18T spur gears designed for the TRAXXAS CRANIAC Monster Truck platform. The components are intended for RC-scale drivetrain replacement and tuning where a metal adapter or steel gears are preferred over OEM plastic parts.

The adapter positions the spur gear on the transmission output, while the steel 58T and 18T gears provide the external gear surfaces that mesh with the pinion and the rest of the gearbox. The set is presented as a single replacement kit for hobbyists maintaining or adjusting gear mesh, noise, and wear characteristics on the TRAXXAS CRANIAC.

Installation typically requires removal of the existing spur gear and adapter assembly, confirming alignment and backlash with the pinion, and securing the adapter per original hardware locations. Inspect the gearbox bearings and mating faces before final assembly to ensure correct mesh and to avoid binding.

This kit is a focused replacement part for the TRAXXAS CRANIAC drivetrain, useful when upgrading the adapter material or replacing worn spur gears; it supports routine maintenance and basic tuning tasks without changing gearbox layout.
