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

Upgraded rear CVD for HOTSHOT II

This aftermarket rear CVD drive shaft is intended for the TAMIYA HOTSHOT II platform and is formed from 4140 medium carbon steel with a thickened, reinforced section to deliver longer wear life than standard dog bone drives. It is designed as a direct rear drivetrain replacement that does not change the chassis layout.

Fitment is for the TAMIYA 1/10 HOTSHOT II 2024-58737-A model. The item replaces the original rear dog bone type drives and comes as a matched left and right pair. Installation uses the vehicle's existing hubs and retaining hardware; verify clearances and mating surfaces during first fit to ensure smooth rotation and proper engagement.

For setup and tuning this piece emphasises drivetrain durability and stiffness rather than altering vehicle balance. Moving to thicker 4140 steel CVDs lowers wear rates during heavy use and helps keep power transfer consistent, but always check axle alignment and bearings to prevent transferring strain to other drivetrain components.

This rear CVD set gives a straightforward durability-focused upgrade for the HOTSHOT II rear drivetrain, fitting directly to extend component life under tough use.
