This 56T main spur is intended for use on Associated RC18T cars and is supplied with an alloy adaptor to match the chassis mounting points. It serves as a spare or upgrade while keeping the original gearbox layout intact.
Choose this titanium option to improve longevity during regular running or when refining throttle and coast feel. The alloy adaptor ensures the assembly stays true under load and keeps fitment straightforward for weekend tuners.
Fitting advice: verify the spur tooth count is 56T for your setup, slide or press the adaptor onto the motor or gearbox interface as applicable, set gear mesh carefully and check for side play before you run. Do not assume fitment for other platforms without confirming adaptor compatibility.
