HRATF25C02 - Aluminum spur gear center insert 3S 4S

Center insert machined from solid 6061‑T6 aluminum to replace the molded plastic spur gear insert in Arrma 3S/4S 4WD drivetrains. The red anodized finish improves wear resistance and aesthetics while adding rigidity to the hub interface. Sized for standard spur gear mounting, it helps maintain consistent gear engagement under load.
