TRAXXAS CRANIAC Spur adapter aluminium with 58T & 18T steel gears CRA155818T by GPM  [CRA155818T]

Replacement aluminium adapter and steel spur gears for CRANIAC

This aftermarket set features an aluminium spur gear adapter and steel 58T and 18T spur gears built for the TRAXXAS CRANIAC Monster Truck drivetrain. It is intended as a service or upgrade option for hobbyists replacing worn plastic components or seeking tougher gear materials.

The adapter mounts the spur to the transmission output and the steel 58T and 18T gears mesh directly with the pinion and the gearbox internals to transfer drive. The kit is supplied as a single replacement to simplify maintenance and basic mesh adjustment.

Installation steps include removing the existing spur and adapter, aligning backlash with the pinion, and securing the new adapter using the original hardware points. Inspect bearings and mating surfaces during reassembly to prevent tight spots.

A compact replacement kit for the TRAXXAS CRANIAC drivetrain that updates adapter material and replaces spur gears while keeping the stock gearbox arrangement.
