GPM Racing 4140 Medium Carbon Steel Rear CVD Drive Shaft Thickened 69mm for Tamiya 1/10 Hotshot II 2024 (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.

Packing includes

• Rear CVD Drive Shaft 69mm - 2pcs

Compatible Models

• TAMIYA 1/10 HOTSHOT II 2024-58737-A

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

What tolerance checks are recommended?

Inspect axial play in the hubs and confirm bearing bore concentricity before final assembly; small misalignments increase stress on the CVD ends.

Are these shafts balanced and matched?

Each set is supplied as a matched left and right pair to maintain symmetrical drivetrain behaviour and minimise runout.

Recommended maintenance after upgrade

Periodically check the shaft ends for wear, verify bearing condition and retorque hub fasteners to spec to maintain optimal load distribution.

Material and longevity considerations

4140 medium carbon steel with a reinforced profile increases fatigue resistance and wear life compared with stock dog bone designs, improving longevity under aggressive driving. Write Product Review Please sign in your account before you can write any review. Sign In Close
