TRAXXAS CRANIAC Aluminium spur adapter and 58T/18T steel gear set CRA155818T by GPM  [CRA155818T]

Durable aluminium adapter with hardened steel spur gears

This aftermarket assembly provides an aluminium spur gear adapter together with steel 58T and 18T spur gears designed around the TRAXXAS CRANIAC Monster Truck drivetrain. The metal parts are intended as a durable replacement where owners want improved wear characteristics over the stock plastic components.

The adapter locates the spur on the transmission output shaft while the steel 58T and 18T gears mesh with the existing pinion and gearbox internals. Supplied as a single service kit, it allows routine replacement and minor tuning of gear mesh and backlash.

Installation generally requires removal of the original spur and adapter, establishing correct backlash, and securing the new adapter using the original mounting points. Check bearings and mating faces during assembly to prevent binding and ensure smooth operation.

A focused replacement for the TRAXXAS CRANIAC drivetrain, this kit helps owners update adapter material and replace worn spur gears while maintaining the original gearbox layout.
