Tamiya TB-04 Front/Rear Steel #45 CVD Swing Shaft by GPM TB4340S  [TB4340S]

CVD swing shaft for TB-04

This is an RC-scale front and rear CVD swing shaft produced by GPM for the Tamiya TB-04 platform and supplied as a single pair. The part is identified as steel #45 in the product name, and is intended as a direct replacement for the TB-04 drivetrain swing shafts where the original style uses CVD swing joints.

Fit and function: the component is intended specifically for TB-04 touring chassis layouts. Use it to replace worn or damaged swing shafts or when you want a consistent steel option in the drivetrain assembly. Because it is a scale RC part, installation procedures follow standard TB-04 maintenance practices and fitment relies on the TB-04 suspension and hub geometry.

Installation and tuning role: the swing shaft mounts into the existing CVD housings and works with the stock TB-04 hubs and outdrives. Install with attention to clearance and bearing engagement, and verify there is no binding through suspension travel. Swapping to a steel #45 shaft affects drivetrain stiffness and long-term wear characteristics, so it is commonly used when durability and consistent drivetrain response are desired during setup and tuning sessions.
