TRAXXAS CRANIAC Aftermarket Aluminium Spur Adapter with Steel 60T & 15T Gears - CRA156015T by GPM  [CRA156015T]

Aluminium adapter paired with steel gears

This aftermarket kit provides an aluminium spur gear adapter plus hardened steel 60T spur and 15T pinion in one set for use with TRAXXAS CRANIAC Monster Truck drivetrains. The metal parts are intended to improve longevity versus the stock plastic components and to stabilise gear engagement for finer tuning.

The adapter secures the spur to correct alignment relative to the motor pinion, while the steel gears are selected for their improved wear resistance. This set is practical when upgrading to higher torque motors or when you want less frequent gear replacement during extended running. Fitting requires ordinary gearbox access and careful mesh adjustment.

Fitment advice: check the adapter for full seating on the shaft, confirm there is no lateral play, use threadlocker on screws if required, and run the drivetrain by hand after initial assembly to confirm smooth operation through the throttle range. This kit is intended for aftermarket maintenance and tuning.

Use this metal gear conversion to reduce wear and achieve a more predictable gear mesh on the CRANIAC; always verify mesh and shaft alignment during installation to avoid unexpected failures.
