Engineered as a service replacement for the Associated RC18T platform, this Delrin 54-tooth main gear is supplied as 1 pcs and is designed to fit common stock gear mounts without modification. The material selection provides low friction running suitable for regular practice and club racing environments.
When installing, verify consistent mesh with the pinion and ensure the gearbox rotates freely under load; small adjustments to motor height or pinion seating will improve engagement and reduce abnormal wear. This component is intended as an aftermarket replacement for the specified chassis and should be fitted following standard maintenance checks.
Replacing a worn main gear with the identical 54T preserves factory final drive ratios while restoring positive engagement. Inspect associated fasteners, bearings and shaft play during service to maintain drivetrain reliability.
