TRAXXAS X-Maxx 18T Hardened Steel Motor Pinion TXM018TS by GPM  [TXM018TS]

18T hardened motor pinion for X-Maxx

This hardened 18T steel motor gear is a single-piece aftermarket pinion for the TRAXXAS 1/8 X-Maxx. It is intended as a direct replacement to correct or alter the motor-to-geartrain mesh using its 18-tooth hardened steel design.

Install this pinion when replacing a worn or broken motor gear or when changing gear ratios for performance tuning. The steel build helps maintain accurate tooth profiles under high loads, improving mesh reliability during hard use.

Fitment notes: remove the motor to access the pinion, set the mesh and backlash to match the spur gear, and re-check the set-screw after a short run. Routine inspections for wear and secure fastening are advised.
