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

Hardened 17T pinion for X-Maxx powertrains

This aftermarket 17-tooth steel motor pinion fits TRAXXAS X-Maxx 1/8 applications and is offered as a durable replacement to restore or change motor-to-spur engagement. The following notes cover fitment, installation steps, and how this 17T pinion influences drivetrain setup.

Fit and role: intended to replace a worn or stock 17T pinion on X-Maxx platforms, the steel construction is selected for increased load resistance and longevity compared with softer materials in heavy-use scenarios. Choose steel when frequent high torque or abrasive conditions are expected.

Installation notes: confirm motor shaft diameter and set screw alignment before mounting, clean the mating surfaces, and set gear mesh using a shim or thin paper method. After fitting, perform a short low-load run to settle the mesh and re-check set screw torque to avoid loosening under use.

Tuning impact: swapping to this 17T steel pinion changes acceleration and top speed relative to other tooth counts; a 17T balances torque and RPM for many 1/8 X-Maxx setups. Adjust motor timing, ESC programming, and spur gear teeth as needed to control motor temperature and performance.
