The TAR054TA is a 54-tooth titanium main gear intended for Associated RC18T cars and is provided with an alloy adaptor to match the transmission input. The titanium spur and alloy adaptor pairing aims to combine long-term wear resistance with consistent mesh alignment.
Compatibility is specific to the Associated RC18T platform; verify your chassis parts list before ordering. Installation needs access to the gearbox bay, standard tools, and a basic understanding of spur gear mesh and backlash settings to avoid undue stress on the motor pinion and gearbox parts.
Use this gear for measured spur changes to tweak final drive ratio, affecting corner exit and top speed. Make small changes between gear sizes, check mesh and runout after fitting, and ensure the gearbox rotates smoothly before full-power runs.
