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

Precision rear CVD for HOTSHOT II applications

This aftermarket rear CVD shaft is engineered for the TAMIYA HOTSHOT II platform using 4140 medium carbon steel with a thickened reinforcement profile to improve fatigue life compared with standard dog bone elements. The component is manufactured to mate directly with the HOTSHOT II rear drivetrain while preserving original geometry and mounting points.

Fitment is for the TAMIYA 1/10 HOTSHOT II 2024-58737-A model. The product supersedes the original rear dog bone drives and is supplied as a matched left and right pair. Installation utilises the vehicle's existing hubs and retaining hardware; inspect mating surfaces and bearing fit during initial assembly to ensure proper engagement and rotation.

From an upgrade standpoint this part prioritises durability and drivetrain stiffness. The thicker 4140 construction reduces wear rates under sustained load and stabilises torque transfer during heavy use. It is recommended to verify axle alignment and replace worn bearings to prevent introducing additional stress into adjacent drivetrain components.

A precision-focused rear CVD set intended to deliver increased service life for HOTSHOT II rear drivetrains while maintaining direct-fit installation characteristics.
