The KO Propo 35522 Hybrid 1st Metal Gear is a direct replacement for the stock plastic gear, designed to improve the durability of PS-2174, PDS-2344, and PDS-2364 servos. It is a practical upgrade for rough use and repeated impacts.
Metal gearing offers greater resistance to stripping and deformation compared to plastic, reducing failure risk during heavy loads or when a steering linkage seizes. It remains important to use a servo saver to shield the motor and remaining gears.
Fitting the KO Propo 35522 requires basic servo disassembly and verification of gear mesh. Use a suitable servo saver and confirm smooth operation across the entire travel before final assembly.
