Tamiya TB04 Graphite Drive Shaft GTB4025 by GPM  [GTB4025]

Graphite prop shaft for TB-04 - overview

This graphite propeller shaft is an aftermarket replacement made for the Tamiya TB04 platform and supplied as 1 pcs. It is intended for use where a graphite shaft is specified for the TB-04 driveline.

The information focuses on fit and tuning: confirmed compatibility with the TB04 designation, usual installation into the rear driveline, and the tuning impact of a stiffer shaft. Graphite typically offers greater stiffness than standard plastics, which affects drivetrain rigidity and the way power is transmitted during driving.

Fitment and setup advice: verify the shaft against TB-04 mounting points and couplers, confirm runout and alignment before final clamping, and inspect mating surfaces for wear. When adjusting the car, check bearing condition, central diff preload, and spur and pinion meshing as these can interact with a stiffer prop shaft.
