This 56T main gear is built to suit Associated RC18T drivetrains and is supplied with an alloy adaptor to meet the chassis-specific mounting interface. It is intended as a replacement or upgrade part that preserves the original gearbox layout.
Use this titanium spur to extend service intervals or refine throttle response. The titanium element combined with an alloy adaptor focuses on consistent geometry under load while remaining simple to install for hobby mechanics.
Fitting notes: ensure the spur you are replacing is 56T, install the alloy adaptor onto the motor or gearbox interface as needed, set correct pinion mesh and confirm there is no excessive lateral play prior to running. Confirm adaptor fit before assuming compatibility with other platforms.
