The Tamiya 3455706 RC Center Shaft Stopper is designed to set the centre shaft in the correct position on the TRF 415 chassis, cutting unwanted movement that can upset drive consistency. Its accurate fit supports reliable power delivery lap after lap.
With a snug fit tailored for the TRF 415, the stopper keeps the drivetrain aligned to reduce slop and improve responsiveness. Precise shaft location helps maintain predictable handling under heavy acceleration and braking.
Fitting the stopper is a routine service task and can be inspected quickly between sessions. Ensuring it seats correctly will protect adjacent gears and bearings and help keep overall drivetrain wear to a minimum.
