GPM TAMIYA TT01 Graphite Main Shaft with Alloy Ends GTT025 - Replacement Part  [GTT025]

TT01 graphite main shaft replacement

This aftermarket graphite main shaft comes with machined alloy end fittings and is made for the TAMIYA TT01 transmission. The graphite mid section reduces torsional twist while the alloy ends ensure consistent seating with bearings and gearbox interfaces.

The unit is compatible with TT01 drivetrain layouts and serves as a direct replacement for the stock shaft without altering gear geometry. Install by locating the shaft in the existing holders and fastening with the original retaining hardware to keep factory alignment.

For tuning the graphite body helps refine driveline feel and the alloy terminations preserve interface accuracy. Inspect bearing alignment and end seating after initial installation and during routine checks to maintain steady power transfer on the track.
