Team Associated RC18T 55T Spur Gear Plastic Replacement RC18-031A by 3Racing  [RC18-031A]

RC18T plastic spur replacement

This 55-tooth plastic spur gear is the RC18-031A replacement sized for the Team Associated RC18T gearbox. It serves as a straightforward service item to replace worn or damaged spur teeth that cause irregular engagement or drivetrain noise.

Fitting is simple for anyone used to small touring truck gearboxes: remove the gearbox cover, inspect the motor pinion and bearings, position the spur for correct mesh with the pinion, and confirm the drivetrain spins freely before finishing. As a plastic gear, verify the mesh and backlash during a short break-in run and check again after initial laps.

Using the 55T spur changes the overall ratio compared with other spur sizes, which will alter acceleration and top speed. Use it as either a stock replacement or part of gradual gearing changes when refining handling and motor loading on the circuit.
