TRAXXAS X-Maxx 1/8 Replacement 17T Steel Motor Pinion TXM017TS by GPM  [TXM017TS]

Steel 17T motor pinion for X-Maxx models

This 17-tooth steel pinion is supplied as an aftermarket replacement for TRAXXAS X-Maxx 1/8 trucks to restore worn gearing or to change final drive ratios. Below are practical notes on compatibility, fitting, and how the pinion will affect vehicle behaviour.

Fit and role: intended as a direct option for X-Maxx setups requiring a 17T pinion, the steel construction improves pinion life in high-stress or abrasive conditions compared with softer materials.

Installation notes: confirm the motor shaft diameter and fastener style, clean the contact areas, and establish the correct mesh with a shim or thin paper method. Perform a short low-load run after fitting and re-check the set screw torque to secure the pinion.

Tuning impact: using this 17T steel pinion will alter acceleration and top speed when compared to other tooth counts; it commonly provides a balanced torque-to-RPM ratio for many 1/8 X-Maxx builds. When changing gearing, monitor motor temperature and adjust ESC settings as required.
