If you need tougher internals, the KO Propo 35536 Metal Gear Set is a direct-fit option for PDS-2511 servos that extends service life. The metal gears are intended to cope with repeated stress from fast driving and rough terrain.
Compared with plastic, metal gears hold tolerances better under load and maintain positional accuracy. Installing this set on a PDS-2511 helps reduce backlash and preserves crisp control inputs during competitive runs.
Great for tuners and regular competitors who want a durable, low-maintenance gear solution for their servos.
