TRAXXAS CRANIAC Aluminium spur gear adapter with 58T & 18T steel gears CRA155818T by GPM  [CRA155818T]

Metal spur adapter and steel gears for TRAXXAS drivetrain

This aftermarket kit replaces the plastic adapter with a machined aluminium spur gear adapter and includes steel 58T and 18T spur gears sized for the TRAXXAS CRANIAC Monster Truck platform. The components are intended for hobbyists who prefer metal parts for improved wear life and more consistent gear mesh compared to the original plastic pieces.

The aluminium adapter locates the main spur on the transmission output while the steel 58T and 18T gears form the mating surfaces that run with the pinion and gearbox internals. The set is supplied as a single replacement kit for maintenance or basic tuning tasks on the CRANIAC drivetrain.

Fitting normally requires removal of the stock spur and adapter, careful alignment of backlash with the pinion, and refitting with the existing hardware locations. Check bearings and contact faces before final assembly to ensure smooth rotation and to prevent binding.

This replacement kit focuses on the TRAXXAS CRANIAC drivetrain, supplying a metal adapter and steel gears for routine upkeep or when upgrading from plastic components without altering gearbox layout.
