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

Heavy-duty rear CVD for HOTSHOT II use

This aftermarket rear CVD shaft is made for the TAMIYA HOTSHOT II platform using 4140 medium carbon steel and a reinforced, thicker profile to extend service life compared with standard dog bone pieces. The component is produced to fit the HOTSHOT II rear layout without changing geometry.

Fitment is for the TAMIYA 1/10 HOTSHOT II 2024-58737-A model. The pair replaces the original rear dog bone style drives and is supplied as left and right matched shafts. Assembly uses the vehicle's existing hubs and retaining hardware; inspect mating surfaces and clearances at first install to ensure correct rotation and engagement.

In practical setup terms this upgrade targets drivetrain longevity and rear stiffness rather than tuning handling traits. Fitting thicker 4140 steel CVDs cuts wear during hard driving and helps sustain consistent torque delivery, though you should confirm axle alignment and bearing condition to avoid introducing new loads to the system.

The set provides a direct-fit rear drivetrain durability upgrade for the HOTSHOT II, aimed at reducing service frequency under heavy running conditions.
