Spur gear for RC18T

This 55-tooth plastic spur gear is supplied by 3Racing as a replacement part intended for use with the Team Associated RC18T chassis. It is an RC-scale component designed to serve as a like-for-like gear inside the car's gearbox, replacing a worn or damaged spur when tooth engagement or drivetrain noise indicates the need for service.

Installation is straightforward for anyone familiar with belt- or gear-driven 1/18 scale touring truck gearboxes: remove the gearbox cover, inspect the mating pinion and bearings for wear, fit the spur so teeth mesh cleanly with the motor pinion, and verify free rotation before reassembling. Because this is a plastic spur, check for proper mesh and backlash during initial runs, and re-inspect after a few laps to confirm stable performance.

In tuning contexts the 55T tooth count affects overall gear ratio compared with smaller or larger spurs, so swapping this spur will change drive characteristics such as acceleration and top speed within the RC setup. Use it as a standard replacement or as part of incremental gearing adjustments when refining on-track handling and motor load.
