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

Precision 17T steel pinion for X-Maxx drivetrains

This 17-tooth steel motor pinion is engineered as an aftermarket replacement for TRAXXAS X-Maxx 1/8 vehicles, intended to provide a hardened option for applications that demand improved pinion longevity. The following technical notes cover compatibility checks, installation procedure, and expected effects on gearing and motor load.

Fit and role: manufactured to suit X-Maxx platforms that require a 17T motor pinion, the steel construction reduces deformation and wear under repeated high torque events versus softer pinions, helping to maintain consistent gear engagement over time.

Installation notes: verify motor shaft diameter and seating method, remove contaminants from bore and shaft, and set precise mesh using a dedicated shim or paper technique. After initial fitting, perform a controlled low-load run, then re-torque the set screw to specification to maintain safe operation during heavy use.

Tuning impact: selecting the TXM017TS 17T pinion will shift acceleration and top speed characteristics relative to other sizes; this tooth count is chosen to balance torque delivery and RPM for many 1/8 X-Maxx configurations. Account for motor timing, ESC parameters, and spur tooth count when changing gear ratios to manage thermal and mechanical stress.
