Tamiya TB04 Graphite Propeller Shaft GTB4025 by GPM  [GTB4025]

TB-04 graphite prop shaft overview

This aftermarket graphite propeller shaft is made for the Tamiya TB04 platform and is supplied as 1 pcs. It is intended as a direct replacement shaft for the TB-04 drivetrain when a graphite component is preferred.

The note for model use covers compatibility with the TB04 designation, typical placement in the rear driveline, and the tuning influence the graphite shaft has. Graphite generally offers higher stiffness than common plastics, which changes drivetrain rigidity and the feel of power transfer in race-oriented setups.

Installation guidance: check fitment against TB-04 mounting points and existing couplers, verify runout and alignment before final tightening, and inspect mating surfaces for wear. For setup tuning, review drivetrain alignment, bearing condition, and any effects on differential preload or spur and pinion mesh that stem from the increased shaft stiffness.
