Tamiya TB-04 Aftermarket Steel #45 CVD Swing Shaft - TB4340S by GPM  [TB4340S]

Replacement shafts for TB-04 CVD system

This matched front and rear CVD swing shaft set fits the Tamiya TB-04 touring platform and is made in steel #45 to serve as replacements for standard CVD swing joints. The design is focused on durability and consistent behaviour under load.

Fit and function: tailored for TB-04 hub geometry and suspension travel, the shafts are intended to replace worn or damaged originals or to standardise on steel drivetrain parts. Installation uses standard TB-04 procedures and relies on accurate hub positioning and bearing seating.

Installation and tuning role: the shafts install into existing CVD housings and are compatible with stock outdrives and wheel hubs. Verify there is no binding through full suspension travel and that bearings are correctly engaged. Choosing steel #45 changes stiffness and wear characteristics, making it a good option when durability and consistent drivetrain feedback are priorities.
