Tamiya TB04 Graphite Prop Shaft GTB4025 by GPM  [GTB4025]

Technical overview for TB-04 graphite prop shaft

This aftermarket graphite propeller shaft is supplied as 1 pcs and is manufactured to suit the Tamiya TB04 platform as a direct replacement component. The part is intended for use where enhanced torsional stiffness is required in the TB-04 driveline.

Performance notes address compatibility with the TB04 designation, the component's position within the rear driveline, and how graphite stiffness impacts drivetrain behaviour. Graphite provides elevated stiffness relative to many injection-moulded plastics, which can reduce twist under torque and alter the transmission of power to the wheels.

Installation and setup recommendations: validate shaft dimensions and coupler interface against TB-04 mounting points, measure and correct any runout before final clamping, and inspect bearing seats and coupling bores for wear. For tuning, monitor bearing condition, re-evaluate central diff preload, and confirm spur and pinion mesh to harmonise the drivetrain with the increased shaft stiffness.
