TRAXXAS X-Maxx Aluminium Adapter with Hardened 54T Spur and 18T Pinion TXM355418T by GPM  [TXM355418T]

Precision aluminium adapter and hardened drivetrain gears

The TXM355418T upgrade kit is an aftermarket replacement for the TRAXXAS 1/8 X-Maxx drivetrain, delivering a machined aluminium adapter paired with a hardened 54T spur and 18T motor pinion. This configuration restores correct pinion position and provides improved resistance to tooth wear compared with softer gear materials.

Suited for high-load RC applications, the aluminium adapter stabilises the pinion and maintains mesh geometry while the hardened steel gears sustain performance under repeated use. Fit this set when replacing degraded components or when validating gear ratios during tuning.

Technical fitment notes: follow the vehicle manufacturer recommended gearbox removal process, inspect bearing condition and shaft runout, install the adapter and gears with the motor in place, set precise gear mesh and confirm smooth free spin before reassembly. Intended for RC model use only.

For precision-minded hobbyists, TXM355418T offers a CNC-style aluminium adapter and hardened steel gearing for reliable mesh and extended service life; verify alignment and mesh during installation to achieve optimal drivetrain behaviour.
