Associated RC 18T 15T Titanium Motor Pinion TAR015T by GPM  [TAR015T]

Lightweight titanium pinion for the Associated 18T motor

This titanium 15T motor gear fits the Associated RC 18T platform and is supplied as a single 15T pinion with its securing screw, intended as a direct replacement or upgrade part for the motor shaft. The titanium construction reduces rotating mass while improving wear resistance where appropriate, and it installs in place of the stock pinion without changing the gear ratio.

During installation confirm tooth count and orientation, then set proper mesh with the spur gear to achieve correct backlash. Tighten the set screw onto the motor shaft flat and verify smooth drivetrain rotation and minimal free play after securing. Routine checks for wear and screw tightness will keep power transfer consistent on the track.

As a like-for-like 15T swap this part preserves original gearing while offering the material benefits of titanium that can change inertia and longevity. Choose it when replacing a worn pinion or when you want a maintenance-focused upgrade without altering final drive ratios.
