Associated RC18T Graphite Main Shaft Spare GAR025 by GPM  [GAR025]

Overview of graphite main shaft for RC18T

This graphite main shaft is manufactured for the Associated RC18T layout and is supplied as a single spare piece. It operates as the direct-drive shaft within the RC18T drivetrain, transferring torque from the motor into the gearbox and the spur and pinion train.

Graphite construction reduces rotating mass while providing a useful level of stiffness compared with some metal alternatives, which can help with acceleration response while retaining adequate strength for normal track and club use. As an aftermarket spare it conforms to RC18T layout so chassis geometry remains unchanged.

Fitting is done inside the gearbox: remove the original main shaft and insert the replacement in the same orientation. After fitting, check spur and pinion alignment, verify gear mesh and ensure bearings are seated correctly. Item sold as 1 pcs intended as a direct replacement or spare for Associated RC18T cars.
