Associated RC18T Graphite Main Shaft by GPM GAR025  [GAR025]

Graphite main shaft for RC18T

This is a graphite main shaft produced for the Associated RC18T platform, supplied as a single pcs replacement. It serves as a direct-drive shaft element in the RC18T drivetrain where the main shaft transfers motor torque into the gearbox and spur/pinion train.

The graphite construction provides a balance of stiffness and low weight compared with some metal options, helping keep rotating mass low while maintaining structural integrity for standard RC track and club use. As an aftermarket part made by GPM it follows the RC18T layout without changing chassis geometry.

Installation is performed in the gearbox area where the original main shaft is removed and the replacement fitted in the same orientation; verify alignment with the spur and pinion, and check mesh and bearing seating after fitment. This item is sold as 1 pcs, intended as a spare or direct replacement for damaged or upgraded shafts on Associated RC18T cars.
