TAMIYA HOTSHOT II Rear CVD Drive Shaft 69mm 4140 Steel - HS2069RS by GPM  [HS2069RS]

Reinforced rear CVD for HOTSHOT II

This reinforced rear CVD shaft is an aftermarket replacement for the TAMIYA HOTSHOT II platform, manufactured from 4140 medium carbon steel with a thicker, strengthened profile to improve wear life versus standard dog bone components. The design keeps the original rear layout so it functions as a direct replacement on the HOTSHOT II rear drivetrain.

Fitment is for the TAMIYA 1/10 HOTSHOT II 2024-58737-A model. The item replaces the original rear dog bone style drives and is supplied as a matched pair for left and right sides. Installation reuses the vehicle's existing hubs and retaining hardware; check mating surfaces and clearances during initial fit to ensure smooth rotation and correct engagement.

From a tuning perspective this component focuses on durability and rear drivetrain stiffness rather than altering handling. The thicker 4140 steel rear CVDs reduce wear under heavy running and help keep power transfer consistent during aggressive driving, but verify axle alignment and bearing condition to avoid adding stress elsewhere in the drivetrain.

This rear CVD set is a simple durability upgrade for the HOTSHOT II rear drivetrain, providing a direct-fit replacement to lengthen service intervals under demanding use.
