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

17-tooth hardened pinion for X-Maxx

Designed as an aftermarket replacement, this 17T steel motor pinion fits TRAXXAS X-Maxx 1/8 models to repair worn pinions or change gearing for tuning. The text that follows covers fitment checks, mounting tips, and expected effects on drivetrain behaviour.

Fit and role: built to replace stock 17T pinions on X-Maxx platforms, the hardened steel choice gives improved resistance to wear under demanding driving compared with softer alloy or brass options.

Installation notes: verify shaft diameter and set screw orientation prior to installation, clean contact surfaces, and set gear mesh with a shim or paper method. After a careful initial run, re-check mesh and fastener torque to prevent mid-run loosening.

Tuning impact: fitting this 17T steel pinion will change acceleration and top speed compared with other sizes; most 1/8 X-Maxx users find 17T a good compromise between torque and RPM. Adjust motor timing and spur gear teeth when re-gearing to manage motor temperatures and performance.
