Tamiya TB04 Prop Shaft Graphite Upgrade GTB4025 by GPM  [GTB4025]

Overview of graphite prop shaft for TB-04

This is an aftermarket graphite propeller shaft made for the Tamiya TB04 platform and supplied as 1 pcs. It serves as a replacement shaft within the TB-04 driveline where graphite material is preferred.

Practical usage notes include confirmed compatibility with the TB04 designation, usual installation into the rear driveline, and the tuning role of a stiffer shaft. Graphite tends to be stiffer than many basic plastics, which can alter driveline stiffness and how power feels through the car during spirited driving.

Fitment advice: check mounting points and coupler compatibility on your TB-04, measure for runout and alignment before final assembly, and inspect mating surfaces for any wear. When tuning, take into account bearing condition, diff preload adjustments, and spur/pinion mesh that may interact with the shaft stiffness.
