Precision 55T Spur for RC18T

Built for the Associated RC18T chassis, this 55-tooth main gear is supplied in titanium with an alloy adaptor for correct gearbox engagement. It serves as a replacement spur where the 55T tooth count is required for specific gearing strategies or handling tweaks.

Installation notes: the product is provided as a single set and the alloy adaptor is used to adapt the gear to the gearbox interface. When installing, check pinion-to-spur clearance and wave washer placement, and verify centre mesh with suspension movement to avoid binding.

Tuning role: the titanium construction increases wear resistance and preserves tooth integrity under sustained load, while the adaptor secures correct seating in non-standard housings. Ideal for lap-time tuning or when a stable 55T count is necessary for driveability changes.

Does this require special tools to fit?

No special tools beyond typical RC assembly tools are needed, though having feeler gauges or a probe helps when setting precise mesh with the adaptor in place.

Will the 55T change my gearing ratios much?

Changing to 55T will alter final drive depending on your pinion choice; plan pinion size accordingly to reach the desired speed and torque balance.

How often should I inspect the spur?

Inspect teeth and seating periodically, especially after heavy use or an impact; titanium resists wear but mounting issues or foreign debris can still affect mesh.
