TRAXXAS CRANIAC Monster Truck Aluminium Spur Adapter & Hardened 60T/15T Gears - CRA156015T by GPM  [CRA156015T]

Metal spur adapter and hardened gear set

This aftermarket set supplies an aluminium spur gear adapter together with hardened steel 60T spur and 15T pinion as a single kit for TRAXXAS CRANIAC Monster Truck owners. The metal components replace the stock plastic parts to reduce wear and give a more consistent mesh for drivetrain tuning and long running sessions.

The aluminium adapter keeps the spur aligned with the motor pinion while the steel 60T spur and 15T pinion provide higher wear resistance where metal gears are preferred. This kit is particularly useful when fitting higher torque motors or for hobbyists who log extended runtime and want to avoid early gear deformation. Installation needs basic gearbox disassembly and careful re-meshing to set correct backlash.

Practical notes: inspect shaft runout and ensure the adapter sits flush without lateral play, apply thread lock to mounting fasteners if the original design requests it, and verify spur-to-pinion mesh at both idle and under acceleration before finishing the build. This is an aftermarket replacement intended for maintenance and tuning of the drivetrain.

Choose this metal-on-metal pairing when you want a firmer adapter mounting and better wear characteristics for routine driving and tuning of the CRANIAC drivetrain; always confirm fit and mesh during installation to avoid premature damage.
