This is an RC-scale spare gear set designed for the 1.8x FCD (full counter drift) rear gear configuration used on Yokomo drift platforms. It serves as a direct replacement to bring the rear gearing back to the specified 1.8x ratio without altering other drivetrain geometry.
Fit this gear to replace worn teeth, recover from gear damage, or return a vehicle to its factory 1.8x FCD rear arrangement. Installation is done inside the rear gearbox; always perform standard gear-mesh and runout checks to avoid premature failure.
Service notes: check and maintain correct mesh clearance between motor pinion and spur, inspect surrounding bearings for any play, and verify alignment under light load before completing assembly. This component is intended solely for model use.
