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

Rear CVD drive shaft for HOTSHOT II

This rear CVD drive shaft is an aftermarket replacement produced for the TAMIYA HOTSHOT II platform, made from 4140 medium carbon steel with a thickened, reinforced profile intended for improved wear life compared with standard dog bone components. The shaft is built to serve as a direct rear drivetrain replacement part on the specified HOTSHOT II chassis without altering layout geometry.

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 uses the vehicle's existing hubs and retaining hardware; check mating surfaces and clearances during first fit to ensure smooth rotation and proper engagement.

In tuning terms this part targets durability and drivetrain stiffness rather than changing handling characteristics. Upgrading to thicker 4140 steel rear CVDs reduces wear under heavy use and helps maintain consistent power transfer during aggressive driving, but remember to verify axle alignment and bearing condition to avoid introducing strain elsewhere in the drivetrain.

This GPM rear CVD set provides a straightforward durability upgrade for the HOTSHOT II rear drivetrain, offering a direct fit replacement to extend service intervals under demanding use.
